ElasticLoadBalancingv2

Client

class ElasticLoadBalancingv2.Client

A low-level client representing Elastic Load Balancing (Elastic Load Balancing v2):

client = session.create_client('elbv2')

These are the available methods:

add_listener_certificates(**kwargs)

Adds the specified SSL server certificate to the certificate list for the specified HTTPS or TLS listener.

If the certificate in already in the certificate list, the call is successful but the certificate is not added again.

To get the certificate list for a listener, use DescribeListenerCertificates . To remove certificates from the certificate list for a listener, use RemoveListenerCertificates . To replace the default certificate for a listener, use ModifyListener .

For more information, see SSL Certificates in the Application Load Balancers Guide .

Examples

This example adds the specified tags to the specified load balancer.

response = client.add_tags(
    ResourceArns=[
        'arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188',
    ],
    Tags=[
        {
            'Key': 'project',
            'Value': 'lima',
        },
        {
            'Key': 'department',
            'Value': 'digital-media',
        },
    ],
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
create_listener(**kwargs)

Creates a listener for the specified Application Load Balancer or Network Load Balancer.

To update a listener, use ModifyListener . When you are finished with a listener, you can delete it using DeleteListener . If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer .

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide .

create_load_balancer(**kwargs)

Creates an Application Load Balancer or a Network Load Balancer.

When you create a load balancer, you can specify security groups, public subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups , SetSubnets , SetIpAddressType , and AddTags .

To create listeners for your load balancer, use CreateListener . To describe your current load balancers, see DescribeLoadBalancers . When you are finished with a load balancer, you can delete it using DeleteLoadBalancer .

For limit information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide and Limits for Your Network Load Balancer in the Network Load Balancers Guide .

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.

For more information, see Application Load Balancers in the Application Load Balancers Guide and Network Load Balancers in the Network Load Balancers Guide .

Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

    The default is an Internet-facing load balancer.

  • Tags (list) --

    One or more tags to assign to the load balancer.

    • (dict) --

      Information about a tag.

          The nodes of an Internet-facing load balancer have public IP addresses. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

          The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

          The ID of the VPC for the load balancer.

        • State (dict) --

          The state of the load balancer.

          • Code (string) --

            The state code. The initial state of the load balancer is provisioning . After the load balancer is fully set up and ready to route traffic, its state is active . If the load balancer could not be set up, its state is failed .

          • Reason (string) --

            A description of the state.

        • Type (string) --

          The type of load balancer.

            • LoadBalancerAddresses (list) --

              [Network Load Balancers] If you need static IP addresses for your load balancer, you can specify one Elastic IP address per Availability Zone when you create an internal-facing load balancer. For internal load balancers, you can specify a private IP address from the IPv4 range of the subnet.

              • (dict) --

                Information about a static IP address for a load balancer.

                • IpAddress (string) --

                  The static IP address.

                • AllocationId (string) --

                  [Network Load Balancers] The allocation ID of the Elastic IP address for an internal-facing load balancer.

                • PrivateIPv4Address (string) --

create_rule(**kwargs)

Creates a rule for the specified listener. The listener must be associated with an Application Load Balancer.

Rules are evaluated in priority order, from the lowest value to the highest value. When the conditions for a rule are met, its actions are performed. If the conditions for no rules are met, the actions for the default rule are performed. For more information, see Listener Rules in the Application Load Balancers Guide .

To view your current rules, use DescribeRules . To update a rule, use ModifyRule . To set the priorities of your rules, use SetRulePriorities . To delete a rule, use DeleteRule .

Parameters
  • ListenerArn (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the listener.

  • Conditions (list) --

    [REQUIRED]

    The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .

    • (dict) --

      Information about a condition for a rule.

      • Field (string) --

        The field in the HTTP request. The following are the possible values:

        • http-header
        • http-request-method
        • host-header
        • path-pattern
        • query-string
        • source-ip
      • Values (list) --

        The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

        If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

        • A-Z, a-z, 0-9
          • .
          • (matches 0 or more characters)
        • ? (matches exactly 1 character)

        If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

        • A-Z, a-z, 0-9
        • _ - . $ / ~ " ' @ : +
        • & (using &)
          • (matches 0 or more characters)
        • ? (matches exactly 1 character)
        • (string) --
      • HostHeaderConfig (dict) --

        Information for a host header condition. Specify only when Field is host-header .

        • Values (list) --

          One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

          • (string) --
      • PathPatternConfig (dict) --

        Information for a path pattern condition. Specify only when Field is path-pattern .

        • Values (list) --

          One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

          • (string) --
      • HttpHeaderConfig (dict) --

        Information for an HTTP header condition. Specify only when Field is http-header .

        • HttpHeaderName (string) --

          The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

          You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

        • Values (list) --

          One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If the same header appears multiple times in the request, we search them in order until a match is found.

          If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

          • (string) --
      • QueryStringConfig (dict) --

        Information for a query string condition. Specify only when Field is query-string .

        • Values (list) --

          One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

          If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

          • (dict) --

            Information about a key/value pair.

            • Key (string) --

              The key. You can omit the key.

            • Value (string) --

              The value.

      • HttpRequestMethodConfig (dict) --

        Information for an HTTP method condition. Specify only when Field is http-request-method .

        • Values (list) --

          The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

          If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

          • (string) --
      • SourceIpConfig (dict) --

        Information for a source IP condition. Specify only when Field is source-ip .

        • Values (list) --

          One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

          If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

          • (string) --
  • Priority (integer) --

    [REQUIRED]

    The rule priority. A listener can't have multiple rules with the same priority.

  • Actions (list) --

          • (dict) --

            Information about a condition for a rule.

            • Field (string) --

              The field in the HTTP request. The following are the possible values:

              • http-header
              • http-request-method
              • host-header
              • path-pattern
              • query-string
              • source-ip
            • Values (list) --

              The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

              If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
                • .
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)

              If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
              • _ - . $ / ~ " ' @ : +

              • (string) --
            • HostHeaderConfig (dict) --

              Information for a host header condition. Specify only when Field is host-header .

              • Values (list) --

                One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

                • (string) --
            • PathPatternConfig (dict) --

              Information for a path pattern condition. Specify only when Field is path-pattern .

              • Values (list) --

                One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

                • (string) --
            • HttpHeaderConfig (dict) --

              Information for an HTTP header condition. Specify only when Field is http-header .

              • HttpHeaderName (string) --

                The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

                You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

              • Values (list) --

                One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If the same header appears multiple times in the request, we search them in order until a match is found.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

                • (string) --
            • QueryStringConfig (dict) --

              Information for a query string condition. Specify only when Field is query-string .

              • Values (list) --

                One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

                If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

                • (dict) --

                  Information about a key/value pair.

                  • Key (string) --

                    The key. You can omit the key.

                  • Value (string) --

            • HttpRequestMethodConfig (dict) --

              Information for an HTTP method condition. Specify only when Field is http-request-method .

              • Values (list) --

                The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

                • (string) --
            • SourceIpConfig (dict) --

              Information for a source IP condition. Specify only when Field is source-ip .

create_target_group(**kwargs)

Creates a target group.

To register targets with the target group, use RegisterTargets . To update the health check settings for the target group, use ModifyTargetGroup . To monitor the health of targets in the target group, use DescribeTargetHealth .

To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule .

To delete a target group, use DeleteTargetGroup .

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple target groups with the same settings, each call succeeds.

For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide or Target Groups for Your Network Load Balancers in the Network Load Balancers Guide .

Parameters
  • Name (string) --

    [REQUIRED]

    The name of the target group.

    This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

  • Protocol (string) -- The protocol to use for routing traffic to the targets. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocols are TCP, TLS, UDP, or TCP_UDP. A TCP_UDP listener must be associated with a TCP_UDP target group. If the target is a Lambda function, this parameter does not apply.
  • Port (integer) -- The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target. If the target is a Lambda function, this parameter does not apply.
  • VpcId (string) -- The identifier of the virtual private cloud (VPC). If the target is a Lambda function, this parameter does not apply. Otherwise, this parameter is required.
  • HealthCheckProtocol (string) -- The protocol the load balancer uses when performing health checks on targets. For Application Load Balancers, the default is HTTP. For Network Load Balancers, the default is TCP. The TCP protocol is supported for health checks only if the protocol of the target group is TCP, TLS, UDP, or TCP_UDP. The TLS, UDP, and TCP_UDP protocols are not supported for health checks.
  • HealthCheckPort (string) -- The port the load balancer uses when performing health checks on targets. The default is traffic-port , which is the port on which each target receives traffic from the load balancer.
  • HealthCheckEnabled (boolean) -- Indicates whether health checks are enabled. If the target type is lambda , health checks are disabled by default but can be enabled. If the target type is instance or ip , health checks are always enabled and cannot be disabled.
  • HealthCheckPath (string) -- [HTTP/HTTPS health checks] The ping path that is the destination on the targets for health checks. The default is /.
  • HealthCheckIntervalSeconds (integer) -- The approximate amount of time, in seconds, between health checks of an individual target. For HTTP and HTTPS health checks, the range is 5–300 seconds. For TCP health checks, the supported values are 10 and 30 seconds. If the target type is instance or ip , the default is 30 seconds. If the target type is lambda , the default is 35 seconds.
  • HealthCheckTimeoutSeconds (integer) -- The amount of time, in seconds, during which no response from a target means a failed health check. For target groups with a protocol of HTTP or HTTPS, the default is 5 seconds. For target groups with a protocol of TCP or TLS, this value must be 6 seconds for HTTP health checks and 10 seconds for TCP and HTTPS health checks. If the target type is lambda , the default is 30 seconds.
  • HealthyThresholdCount (integer) -- The number of consecutive health checks successes required before considering an unhealthy target healthy. For target groups with a protocol of HTTP or HTTPS, the default is 5. For target groups with a protocol of TCP or TLS, the default is 3. If the target type is lambda , the default is 5.
  • UnhealthyThresholdCount (integer) -- The number of consecutive health check failures required before considering a target unhealthy. For target groups with a protocol of HTTP or HTTPS, the default is 2. For target groups with a protocol of TCP or TLS, this value must be the same as the healthy threshold count. If the target type is lambda , the default is 2.
  • Matcher (dict) --

    [HTTP/HTTPS health checks] The HTTP codes to use when checking for a successful response from a target.

    • HttpCode (string) -- [REQUIRED]

      The HTTP codes.

      For Application Load Balancers, you can specify values between 200 and 499, and the default value is 200. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").

      For Network Load Balancers, this is 200–399.

  • TargetType (string) --

    The type of target that you must specify when registering targets with this target group. You can't specify targets for a target group using more than one target type.

    • instance - Targets are specified by instance ID. This is the default value. If the target group protocol is UDP or TCP_UDP, the target type must be instance .
    • ip - Targets are specified by IP address. You can specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't specify publicly routable IP addresses.
    • lambda - The target groups contains a single Lambda function.

Request Syntax

response = client.deregister_targets(
    TargetGroupArn='string',
    Targets=[
        {
            'Id': 'string',
            'Port': 123,
            'AvailabilityZone': 'string'
        },
    ]
)
Parameters
  • TargetGroupArn (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the target group.

  • Targets (list) --

    [REQUIRED]

    The targets. If you specified a port override when you registered a target, you must specify both the target ID and the port when you deregister it.

    • (dict) --

      Information about a target.

      • Id (string) -- [REQUIRED]

        The ID of the target. If the target type of the target group is instance , specify an instance ID. If the target type is ip , specify an IP address. If the target type is lambda , specify the ARN of the Lambda function.

      • Port (integer) --

        The port on which the target is listening. Not used if the target is a Lambda function.

      • AvailabilityZone (string) --

        An Availability Zone or all . This determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.

        This parameter is not supported if the target type of the target group is instance .

        If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.

        With an Application Load Balancer, if the target type is ip and the IP address is outside the VPC for the target group, the only supported value is all .

        If the target type is lambda , this parameter is optional and the only supported value is all .

      • (dict) --

        Information about a rule.

        • RuleArn (string) --

          The Amazon Resource Name (ARN) of the rule.

        • Priority (string) --

          The priority.

        • Conditions (list) --

          The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .

          • (dict) --

            Information about a condition for a rule.

            • Field (string) --

              The field in the HTTP request. The following are the possible values:

              • http-header
              • http-request-method
              • host-header
              • path-pattern
              • query-string
              • source-ip
            • Values (list) --

              The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

              If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
                • .
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)

              If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
              • _ - . $ / ~ " ' @ : +
              • & (using &)
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)
              • (string) --
            • HostHeaderConfig (dict) --

              Information for a host header condition. Specify only when Field is host-header .

              • Values (list) --

                One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

                • (string) --
            • PathPatternConfig (dict) --

              Information for a path pattern condition. Specify only when Field is path-pattern .

              • Values (list) --

                One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

                • (string) --
            • HttpHeaderConfig (dict) --

              Information for an HTTP header condition. Specify only when Field is http-header .

              • HttpHeaderName (string) --

                The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

                You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

              • Values (list) --

                One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If the same header appears multiple times in the request, we search them in order until a match is found.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

                • (string) --
            • QueryStringConfig (dict) --

              Information for a query string condition. Specify only when Field is query-string .

              • Values (list) --

                One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

                If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

                • (dict) --

                  Information about a key/value pair.

                  • Key (string) --

                    The key. You can omit the key.

                  • Value (string) --

                    The value.

            • HttpRequestMethodConfig (dict) --

              Information for an HTTP method condition. Specify only when Field is http-request-method .

              • Values (list) --

                The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

                • (string) --
            • SourceIpConfig (dict) --

              Information for a source IP condition. Specify only when Field is source-ip .

              • Values (list) --

                One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

                If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

                • (string) --
        • Actions (list) --

      • (dict) --

        Information about a target group attribute.

        • Key (string) --

          The name of the attribute.

          The following attribute is supported by both Application Load Balancers and Network Load Balancers:

          • deregistration_delay.timeout_seconds - The amount of time, in seconds, for Elastic Load Balancing to wait before changing the state of a deregistering target from draining to unused . The range is 0-3600 seconds. The default value is 300 seconds. If the target is a Lambda function, this attribute is not supported.

          The following attributes are supported by Application Load Balancers if the target is not a Lambda function:

          • load_balancing.algorithm.type - The load balancing algorithm determines how the load balancer selects targets when routing requests. The value is round_robin or least_outstanding_requests . The default is round_robin .
          • slow_start.duration_seconds - The time period, in seconds, during which a newly registered target receives a linearly increasing share of the traffic to the target group. After this time period ends, the target receives its full share of traffic. The range is 30-900 seconds (15 minutes). Slow start mode is disabled by default.
          • stickiness.enabled - Indicates whether sticky sessions are enabled. The value is true or false . The default is false .
          • stickiness.type - The type of sticky sessions. The possible value is lb_cookie .
          • stickiness.lb_cookie.duration_seconds - The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the load balancer-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).

          The following attribute is supported only if the target is a Lambda function.

          • lambda.multi_value_headers.enabled - Indicates whether the request and response headers exchanged between the load balancer and the Lambda function include arrays of values or strings. The value is true or false . The default is false . If the value is false and the request contains a duplicate header field name or query parameter key, the load balancer uses the last value sent by the client.

          The following attribute is supported only by Network Load Balancers:

          • proxy_protocol_v2.enabled - Indicates whether Proxy Protocol version 2 is enabled. The value is true or false . The default is false .
        • Value (string) --

          The value of the attribute.

            This parameter is not supported if the target type of the target group is instance .

            If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.

            With an Application Load Balancer, if the target type is ip and the IP address is outside the VPC for the target group, the only supported value is all .

            If the target type is lambda , this parameter is optional and the only supported value is all .

        • HealthCheckPort (string) --

          The port to use to connect with the target.

        • TargetHealth (dict) --

          The health information for the target.

          • State (string) --

            The state of the target.

          • Reason (string) --

            The reason code.

            If the target state is healthy , a reason code is not provided.

            If the target state is initial , the reason code can be one of the following values:

            • Elb.RegistrationInProgress - The target is in the process of being registered with the load balancer.
            • Elb.InitialHealthChecking - The load balancer is still sending the target the minimum number of health checks required to determine its health status.

            If the target state is unhealthy , the reason code can be one of the following values:

            • Target.ResponseCodeMismatch - The health checks did not return an expected HTTP code. Applies only to Application Load Balancers.
            • Target.Timeout - The health check requests timed out. Applies only to Application Load Balancers.
            • Target.FailedHealthChecks - The load balancer received an error while establishing a connection to the target or the target response was malformed.
            • Elb.InternalError - The health checks failed due to an internal error. Applies only to Application Load Balancers.

            If the target state is unused , the reason code can be one of the following values:

            • Target.NotRegistered - The target is not registered with the target group.
            • Target.NotInUse - The target group is not used by any load balancer or the target is in an Availability Zone that is not enabled for its load balancer.
            • Target.InvalidState - The target is in the stopped or terminated state.
            • Target.IpUnusable - The target IP address is reserved for use by a load balancer.

            • Target.DeregistrationInProgress - The target is in the process of being deregistered and the deregistration delay period has not expired.

            If the target state is unavailable , the reason code can be the following value:

            • Target.HealthCheckDisabled - Health checks are disabled for the target group. Applies only to Application Load Balancers.
            • Elb.InternalError - Target health is unavailable due to an internal error. Applies only to Network Load Balancers.
          • Description (string) --

            A description of the target health that provides additional details. If the state is healthy , a description is not provided.

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)

Generate a presigned url given a client, its method, and arguments

Parameters
  • ClientMethod (string) -- The client method to presign for
  • Params (dict) -- The parameters normally passed to ClientMethod.
  • ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)

The presigned url

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
get_waiter(waiter_name)

Returns an object that can wait for some condition.

Parameters
waiter_name (str) -- The name of the waiter to get. See the waiters section of the service docs for a list of available waiters.
Returns
The specified waiter object.
Return type
botocore.waiter.Waiter
modify_listener(**kwargs)

Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.

Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.

To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.

Parameters
  • RuleArn (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the rule.

  • Conditions (list) --

    The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .

    • (dict) --

      Information about a condition for a rule.

      • Field (string) --

        The field in the HTTP request. The following are the possible values:

        • http-header
        • http-request-method
        • host-header
        • path-pattern
        • query-string
        • source-ip
      • Values (list) --

        The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

        If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

        • A-Z, a-z, 0-9
          • .
          • (matches 0 or more characters)
        • ? (matches exactly 1 character)

        If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

        • A-Z, a-z, 0-9
        • _ - . $ / ~ " ' @ : +
        • & (using &)
          • (matches 0 or more characters)
        • ? (matches exactly 1 character)
        • (string) --
      • HostHeaderConfig (dict) --

        Information for a host header condition. Specify only when Field is host-header .

        • Values (list) --

          One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

          • (string) --
      • PathPatternConfig (dict) --

        Information for a path pattern condition. Specify only when Field is path-pattern .

        • Values (list) --

          One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

          • (string) --
      • HttpHeaderConfig (dict) --

        Information for an HTTP header condition. Specify only when Field is http-header .

        • HttpHeaderName (string) --

          The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

          You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

        • Values (list) --

          One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

          If the same header appears multiple times in the request, we search them in order until a match is found.

          If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

          • (string) --
      • QueryStringConfig (dict) --

        Information for a query string condition. Specify only when Field is query-string .

        • Values (list) --

          One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

          If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

          • (dict) --

            Information about a key/value pair.

            • Key (string) --

              The key. You can omit the key.

            • Value (string) --

              The value.

      • HttpRequestMethodConfig (dict) --

        Information for an HTTP method condition. Specify only when Field is http-request-method .

        • Values (list) --

          The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

          If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

          • (string) --
      • SourceIpConfig (dict) --

        Information for a source IP condition. Specify only when Field is source-ip .

        • Values (list) --

          One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

          If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

          • (string) --
  • Actions (list) --

    The actions. Each rule must include exactly one of the following types of actions: forward , fixed-response , or redirect , and it must be the last action to be performed.

    If the action type is forward , you specify one or more target groups. The protocol of the target group must be HTTP or HTTPS for an Application Load Balancer. The protocol of the target group must be TCP, TLS, UDP, or TCP_UDP for a Network Load Balancer.

    [HTTPS listeners] If the action type is authenticate-oidc , you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.

    [HTTPS listeners] If the action type is authenticate-cognito , you authenticate users through the user pools supported by Amazon Cognito.

    [Application Load Balancer] If the action type is redirect , you redirect specified client requests from one URL to another.

    [Application Load Balancer] If the action type is fixed-response , you drop specified client requests and return a custom HTTP response.

          • (dict) --

            Information about a condition for a rule.

            • Field (string) --

              The field in the HTTP request. The following are the possible values:

              • http-header
              • http-request-method
              • host-header
              • path-pattern
              • query-string
              • source-ip
            • Values (list) --

              The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

              If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
                • .
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)

              If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
              • _ - . $ / ~ " ' @ : +
              • & (using &)
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)
              • (string) --
            • HostHeaderConfig (dict) --

              Information for a host header condition. Specify only when Field is host-header .

              • Values (list) --

                One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

                • (string) --
            • PathPatternConfig (dict) --

              Information for a path pattern condition. Specify only when Field is path-pattern .

              • Values (list) --

                One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

                • (string) --
            • HttpHeaderConfig (dict) --

              Information for an HTTP header condition. Specify only when Field is http-header .

              • HttpHeaderName (string) --

                The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

                You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

              • Values (list) --

                One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If the same header appears multiple times in the request, we search them in order until a match is found.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

                • (string) --
            • QueryStringConfig (dict) --

              Information for a query string condition. Specify only when Field is query-string .

              • Values (list) --

                One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

                If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

                • (dict) --

                  Information about a key/value pair.

                  • Key (string) --

                    The key. You can omit the key.

                  • Value (string) --

                    The value.

            • HttpRequestMethodConfig (dict) --

              Information for an HTTP method condition. Specify only when Field is http-request-method .

              • Values (list) --

                The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

                • (string) --
            • SourceIpConfig (dict) --

              Information for a source IP condition. Specify only when Field is source-ip .

              • Values (list) --

                One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

                If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

                • (string) --
        • Actions (list) --

          The actions. Each rule must include exactly one of the following types of actions: forward , redirect , or fixed-response , and it must be the last action to be performed.

register_targets(**kwargs)

Registers the specified targets with the specified target group.

If the target is an EC2 instance, it must be in the running state when you register it.

By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.

With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

To remove a target from a target group, use DeregisterTargets .

          • (dict) --

            Information about a condition for a rule.

            • Field (string) --

              The field in the HTTP request. The following are the possible values:

              • http-header
              • http-request-method
              • host-header
              • path-pattern
              • query-string
              • source-ip
            • Values (list) --

              The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

              If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
                • .
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)

              If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
              • _ - . $ / ~ " ' @ : +
              • & (using &)

              • ? (matches exactly 1 character)
              • (string) --
            • HostHeaderConfig (dict) --

              Information for a host header condition. Specify only when Field is host-header .

              • Values (list) --

                One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

                • (string) --
            • PathPatternConfig (dict) --

              Information for a path pattern condition. Specify only when Field is path-pattern .

              • Values (list) --

                One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

                • (string) --
            • HttpHeaderConfig (dict) --

              Information for an HTTP header condition. Specify only when Field is http-header .

              • HttpHeaderName (string) --

                The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

                You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

              • Values (list) --

                One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If the same header appears multiple times in the request, we search them in order until a match is found.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

                • (string) --
            • QueryStringConfig (dict) --

              Information for a query string condition. Specify only when Field is query-string .

              • Values (list) --

                One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

                If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

                • (dict) --

                  Information about a key/value pair.

                  • Key (string) --

                    The key. You can omit the key.

                  • Value (string) --

                    The value.

            • HttpRequestMethodConfig (dict) --

              Information for an HTTP method condition. Specify only when Field is http-request-method .

              • Values (list) --

                The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

                • (string) --
            • SourceIpConfig (dict) --

              Information for a source IP condition. Specify only when Field is source-ip .

              • Values (list) --

                One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

                If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

                • (string) --
        • Actions (list) --

          The actions. Each rule must include exactly one of the following types of actions: forward , redirect , or fixed-response , and it must be the last action to be performed.

      Information about the rules.

      • (dict) --

        Information about a rule.

        • RuleArn (string) --

          The Amazon Resource Name (ARN) of the rule.

        • Priority (string) --

          The priority.

        • Conditions (list) --

          The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .

          • (dict) --

            Information about a condition for a rule.

            • Field (string) --

              The field in the HTTP request. The following are the possible values:

              • http-header
              • http-request-method
              • host-header
              • path-pattern
              • query-string
              • source-ip
            • Values (list) --

              The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.

              If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
                • .
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)

              If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

              • A-Z, a-z, 0-9
              • _ - . $ / ~ " ' @ : +
              • & (using &)
                • (matches 0 or more characters)
              • ? (matches exactly 1 character)
              • (string) --
            • HostHeaderConfig (dict) --

              Information for a host header condition. Specify only when Field is host-header .

              • Values (list) --

                One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

                • (string) --
            • PathPatternConfig (dict) --

              Information for a path pattern condition. Specify only when Field is path-pattern .

              • Values (list) --

                One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

                • (string) --
            • HttpHeaderConfig (dict) --

              Information for an HTTP header condition. Specify only when Field is http-header .

              • HttpHeaderName (string) --

                The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

                You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

              • Values (list) --

                One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

                If the same header appears multiple times in the request, we search them in order until a match is found.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

                • (string) --
            • QueryStringConfig (dict) --

              Information for a query string condition. Specify only when Field is query-string .

              • Values (list) --

                One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

                If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

                • (dict) --

                  Information about a key/value pair.

                  • Key (string) --

                    The key. You can omit the key.

                  • Value (string) --

                    The value.

            • HttpRequestMethodConfig (dict) --

              Information for an HTTP method condition. Specify only when Field is http-request-method .

              • Values (list) --

                The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

                If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

                • (string) --
            • SourceIpConfig (dict) --

              Information for a source IP condition. Specify only when Field is source-ip .

              • Values (list) --

                One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

                If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

                • (string) --
        • Actions (list) --

          The actions. Each rule must include exactly one of the following types of actions: forward , redirect , or fixed-response , and it must be the last action to be performed.
