create_transit_gateway_vpc_attachment#

EC2.Client.create_transit_gateway_vpc_attachment(**kwargs)#

Attaches the specified VPC to the specified transit gateway.

If you attach a VPC with a CIDR range that overlaps the CIDR range of a VPC that is already attached, the new VPC CIDR range is not propagated to the default propagation route table.

To send VPC traffic to an attached transit gateway, add a route to the VPC route table using CreateRoute.

Parameters:

TransitGatewayId (string) –
[REQUIRED]

The ID of the transit gateway.
VpcId (string) –
[REQUIRED]

The ID of the VPC.
SubnetIds (list) –
[REQUIRED]

The IDs of one or more subnets. You can specify only one subnet per Availability Zone. You must specify at least one subnet, but we recommend that you specify two subnets for better availability. The transit gateway uses one IP address from each specified subnet.
- (string) –
Options (dict) –
The VPC attachment options.
- DnsSupport (string) –
  
  Enable or disable DNS support. The default is enable.
- SecurityGroupReferencingSupport (string) –
  
  Enables you to reference a security group across VPCs attached to a transit gateway to simplify security group management.
  
  This option is set to enable by default. However, at the transit gateway level the default is set to disable.
  
  For more information about security group referencing, see Security group referencing in the Amazon Web Services Transit Gateways Guide.
- Ipv6Support (string) –
  
  Enable or disable IPv6 support. The default is disable.
- ApplianceModeSupport (string) –
  
  Enable or disable support for appliance mode. If enabled, a traffic flow between a source and destination uses the same Availability Zone for the VPC attachment for the lifetime of that flow. The default is disable.
TagSpecifications (list) –
The tags to apply to the VPC attachment.
- (dict) –
  
  The tags to apply to a resource when the resource is being created. When you specify a tag, you must specify the resource type to tag, otherwise the request will fail.
  
  Note
  The Valid Values lists all the resource types that can be tagged. However, the action you’re using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you’re using, you’ll get an error.
  - ResourceType (string) –
    
    The type of resource to tag on creation.
  - Tags (list) –
    
    The tags to apply to the resource.
    - (dict) –
      
      Describes a tag.
      - Key (string) –
        
        The key of the tag.
        
        Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with aws:.
      - Value (string) –
        
        The value of the tag.
        
        Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.
DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Return type:

dict
