EFS

Client

class EFS.Client

A low-level client representing Amazon Elastic File System (EFS):

client = session.create_client('efs')

These are the available methods:

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_access_point(**kwargs)

Creates an EFS access point. An access point is an application-specific view into an EFS file system that applies an operating system user and group, and a file system path, to any file system request made through the access point. The operating system user and group override any identity information provided by the NFS client. The file system path is exposed as the access point's root directory. Applications using the access point can only access data in its own directory and below. To learn more, see Mounting a File System Using EFS Access Points .

This operation requires permissions for the elasticfilesystem:CreateAccessPoint action.

Exceptions

create_file_system(**kwargs)

Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's AWS account with the specified creation token, this operation does the following:

  • Creates a new, empty file system. The file system will have an Amazon EFS assigned ID, and an initial lifecycle state creating .
  • Returns with the description of the created file system.

Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system.

Note

For basic use cases, you can use a randomly generated UUID for the creation token.

The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error.

Note

The CreateFileSystem call returns while the file system's lifecycle state is still creating . You can check the file system creation status by calling the DescribeFileSystems operation, which among other things returns the file system state.

This operation also takes an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. The performance mode can't be changed after the file system has been created. For more information, see Amazon EFS: Performance Modes .

After the file system is fully created, Amazon EFS sets its lifecycle state to available , at which point you can create one or more mount targets for the file system in your VPC. For more information, see CreateMountTarget . You mount your Amazon EFS file system on an EC2 instances in your VPC by using the mount target. For more information, see Amazon EFS: How it Works .

This operation requires permissions for the elasticfilesystem:CreateFileSystem action.

Parameters
  • CreationToken (string) --

    [REQUIRED]

    A string of up to 64 ASCII characters. Amazon EFS uses this to ensure idempotent creation.

    This field is autopopulated if not provided.

  • PerformanceMode (string) -- The performance mode of the file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. The performance mode can't be changed after the file system has been created.
  • Encrypted (boolean) -- A Boolean value that, if true, creates an encrypted file system. When creating an encrypted file system, you have the option of specifying CreateFileSystemRequest$KmsKeyId for an existing AWS Key Management Service (AWS KMS) customer master key (CMK). If you don't specify a CMK, then the default CMK for Amazon EFS, /aws/elasticfilesystem , is used to protect the encrypted file system.
  • KmsKeyId (string) --

    The ID of the AWS KMS CMK to be used to protect the encrypted file system. This parameter is only required if you want to use a nondefault CMK. If this parameter is not specified, the default CMK for Amazon EFS is used. This ID can be in one of the following formats:

    • Key ID - A unique identifier of the key, for example 1234abcd-12ab-34cd-56ef-1234567890ab .
    • ARN - An Amazon Resource Name (ARN) for the key, for example arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab .
    • Key alias - A previously created display name for a key, for example alias/projectKey1 .
    • Key alias ARN - An ARN for a key alias, for example arn:aws:kms:us-west-2:444455556666:alias/projectKey1 .

    If KmsKeyId is specified, the CreateFileSystemRequest$Encrypted parameter must be set to true.

    Warning

    EFS accepts only symmetric CMKs. You cannot use asymmetric CMKs with EFS file systems.

  • ThroughputMode (string) -- The throughput mode for the file system to be created. There are two throughput modes to choose from for your file system: bursting and provisioned . If you set ThroughputMode to provisioned , you must also set a value for ProvisionedThroughPutInMibps . You can decrease your file system's throughput in Provisioned Throughput mode or change between the throughput modes as long as it’s been more than 24 hours since the last decrease or throughput mode change. For more, see Specifying Throughput with Provisioned Mode in the Amazon EFS User Guide.
  • ProvisionedThroughputInMibps (float) -- The throughput, measured in MiB/s, that you want to provision for a file system that you're creating. Valid values are 1-1024. Required if ThroughputMode is set to provisioned . The upper limit for throughput is 1024 MiB/s. You can get this limit increased by contacting AWS Support. For more information, see Amazon EFS Limits That You Can Increase in the Amazon EFS User Guide.
  • Tags (list) --

    A value that specifies to create one or more tags associated with the file system. Each tag is a user-defined key-value pair. Name your file system on creation by including a "Key":"Name","Value":"{value}" key-value pair.

    • (dict) --

      A tag is a key-value pair. Allowed characters are letters, white space, and numbers that can be represented in UTF-8, and the following characters:+ - = . _ : /

      • Key (string) -- [REQUIRED]

        The tag key (String). The key can't start with aws: .

create_mount_target(**kwargs)

Creates a mount target for a file system. You can then mount the file system on EC2 instances by using the mount target.

You can create one mount target in each Availability Zone in your VPC. All EC2 instances in a VPC within a given Availability Zone share a single mount target for a given file system. If you have multiple subnets in an Availability Zone, you create a mount target in one of the subnets. EC2 instances do not need to be in the same subnet as the mount target in order to access their file system. For more information, see Amazon EFS: How it Works .

In the request, you also specify a file system ID for which you are creating the mount target and the file system's lifecycle state must be available . For more information, see DescribeFileSystems .

In the request, you also provide a subnet ID, which determines the following:

  • VPC in which Amazon EFS creates the mount target
  • Availability Zone in which Amazon EFS creates the mount target
  • IP address range from which Amazon EFS selects the IP address of the mount target (if you don't specify an IP address in the request)

After creating the mount target, Amazon EFS returns a response that includes, a MountTargetId and an IpAddress . You use this IP address when mounting the file system in an EC2 instance. You can also use the mount target's DNS name when mounting the file system. The EC2 instance on which you mount the file system by using the mount target can resolve the mount target's DNS name to its IP address. For more information, see How it Works: Implementation Overview .

Note that you can create mount targets for a file system in only one VPC, and there can be only one mount target per Availability Zone. That is, if the file system already has one or more mount targets created for it, the subnet specified in the request to add another mount target must meet the following requirements:

  • Must belong to the same VPC as the subnets of the existing mount targets
  • Must not be in the same Availability Zone as any of the subnets of the existing mount targets

If the request satisfies the requirements, Amazon EFS does the following:

  • Creates a new mount target in the specified subnet.
  • Also creates a new network interface in the subnet as follows:
    • If the request provides an IpAddress , Amazon EFS assigns that IP address to the network interface. Otherwise, Amazon EFS assigns a free address in the subnet (in the same way that the Amazon EC2 CreateNetworkInterface call does when a request does not specify a primary private IP address).
    • If the request provides SecurityGroups , this network interface is associated with those security groups. Otherwise, it belongs to the default security group for the subnet's VPC.
    • Assigns the description Mount target *fsmt-id* for file system *fs-id* `` where `` *fsmt-id* `` is the mount target ID, and `` *fs-id* `` is the ``FileSystemId .
    • Sets the requesterManaged property of the network interface to true , and the requesterId value to EFS .

Each Amazon EFS mount target has one corresponding requester-managed EC2 network interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId field in the mount target's description to the network interface ID, and the IpAddress field to its address. If network interface creation fails, the entire CreateMountTarget operation fails.

Note

The CreateMountTarget call returns only after creating the network interface, but while the mount target state is still creating , you can check the mount target creation status by calling the DescribeMountTargets operation, which among other things returns the mount target state.

We recommend that you create a mount target in each of the Availability Zones. There are cost considerations for using a file system in an Availability Zone through a mount target created in another Availability Zone. For more information, see Amazon EFS . In addition, by always using a mount target local to the instance's Availability Zone, you eliminate a partial failure scenario. If the Availability Zone in which your mount target is created goes down, then you can't access your file system through that mount target.

This operation requires permissions for the following action on the file system:

  • elasticfilesystem:CreateMountTarget

This operation also requires permissions for the following Amazon EC2 actions:

  • ec2:DescribeSubnets
  • ec2:DescribeNetworkInterfaces
  • ec2:CreateNetworkInterface

}
create_tags(**kwargs)

Creates or overwrites tags associated with a file system. Each tag is a key-value pair. If a tag key specified in the request already exists on the file system, this operation overwrites its value with the value provided in the request. If you add the Name tag to your file system, Amazon EFS returns it in the response to the DescribeFileSystems operation.

This operation requires permission for the elasticfilesystem:CreateTags action.

Danger

This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.

}
delete_access_point(**kwargs)

Deletes the specified access point. After deletion is complete, new clients can no longer connect to the access points. Clients connected to the access point at the time of deletion will continue to function until they terminate their connection.

This operation requires permissions for the elasticfilesystem:DeleteAccessPoint action.

See also: AWS API Documentation

Request Syntax

response = client.delete_access_point(
    AccessPointId='string'
)
Parameters
AccessPointId (string) --

[REQUIRED]

The ID of the access point that you want to delete.

Returns
None

Exceptions

delete_file_system(**kwargs)

Deletes a file system, permanently severing access to its contents. Upon return, the file system no longer exists and you can't access any contents of the deleted file system.

You can't delete a file system that is in use. That is, if the file system has any mount targets, you must first delete them. For more information, see DescribeMountTargets and DeleteMountTarget .

Note

The DeleteFileSystem call returns while the file system state is still deleting . You can check the file system deletion status by calling the DescribeFileSystems operation, which returns a list of file systems in your account. If you pass file system ID or creation token for the deleted file system, the DescribeFileSystems returns a 404 FileSystemNotFound error.

This operation requires permissions for the elasticfilesystem:DeleteFileSystem action.

See also: AWS API Documentation

Request Syntax

response = client.delete_file_system(
    FileSystemId='string'
)
Parameters
FileSystemId (string) --

[REQUIRED]

The ID of the file system you want to delete.

Returns
None

Exceptions

Examples

This operation deletes an EFS file system.

response = client.delete_file_system(
    FileSystemId='fs-01234567',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
delete_file_system_policy(**kwargs)

Deletes the FileSystemPolicy for the specified file system. The default FileSystemPolicy goes into effect once the existing policy is deleted. For more information about the default file system policy, see Using Resource-based Policies with EFS .

This operation requires permissions for the elasticfilesystem:DeleteFileSystemPolicy action.

See also: AWS API Documentation

Request Syntax

response = client.delete_file_system_policy(
    FileSystemId='string'
)
Parameters
FileSystemId (string) --

[REQUIRED]

Specifies the EFS file system for which to delete the FileSystemPolicy .

Returns
None

Exceptions

delete_mount_target(**kwargs)

Deletes the specified mount target.

This operation forcibly breaks any mounts of the file system by using the mount target that is being deleted, which might disrupt instances or applications using those mounts. To avoid applications getting cut off abruptly, you might consider unmounting any mounts of the mount target, if feasible. The operation also deletes the associated network interface. Uncommitted writes might be lost, but breaking a mount target using this operation does not corrupt the file system itself. The file system you created remains. You can mount an EC2 instance in your VPC by using another mount target.

This operation requires permissions for the following action on the file system:

  • elasticfilesystem:DeleteMountTarget

Note

The DeleteMountTarget call returns while the mount target state is still deleting . You can check the mount target deletion by calling the DescribeMountTargets operation, which returns a list of mount target descriptions for the given file system.

The operation also requires permissions for the following Amazon EC2 action on the mount target's network interface:

  • ec2:DeleteNetworkInterface

See also: AWS API Documentation

Request Syntax

response = client.delete_mount_target(
    MountTargetId='string'
)
Parameters
MountTargetId (string) --

[REQUIRED]

The ID of the mount target to delete (String).

Returns
None

Exceptions

Examples

This operation deletes a mount target.

response = client.delete_mount_target(
    MountTargetId='fsmt-12340abc',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
delete_tags(**kwargs)

Deletes the specified tags from a file system. If the DeleteTags request includes a tag key that doesn't exist, Amazon EFS ignores it and doesn't cause an error. For more information about tags and related restrictions, see Tag Restrictions in the AWS Billing and Cost Management User Guide .

This operation requires permissions for the elasticfilesystem:DeleteTags action.

Danger

This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.

Response Structure

  • (dict) --
    • FileSystemId (string) --

      Specifies the EFS file system to which the FileSystemPolicy applies.

    • Policy (string) --

      The JSON formatted FileSystemPolicy for the EFS file system.

Exceptions

describe_file_systems(**kwargs)

Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided. Otherwise, it returns descriptions of all file systems owned by the caller's AWS account in the AWS Region of the endpoint that you're calling.

When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. Currently, this number is automatically set to 10. If more file system descriptions remain, Amazon EFS returns a NextMarker , an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker .

To retrieve a list of your file system descriptions, this operation is used in an iterative process, where DescribeFileSystems is called first without the Marker and then the operation continues to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker .

The order of file systems returned in the response of one DescribeFileSystems call and the order of file systems returned across the responses of a multi-call iteration is unspecified.

This operation requires permissions for the elasticfilesystem:DescribeFileSystems action.

A file system always has exactly one file system policy, which can be the default policy or an explicit policy set or updated using this API operation. When an explicit policy is set, it overrides the default policy. For more information about the default file system policy, see Default EFS File System Policy .

This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.

See also: AWS API Documentation

Request Syntax

response = client.put_file_system_policy(
    FileSystemId='string',
    Policy='string',
    BypassPolicyLockoutSafetyCheck=True|False

Exceptions

put_lifecycle_configuration(**kwargs)

Enables lifecycle management by creating a new LifecycleConfiguration object. A LifecycleConfiguration object defines when files in an Amazon EFS file system are automatically transitioned to the lower-cost EFS Infrequent Access (IA) storage class. A LifecycleConfiguration applies to all files in a file system.

Each Amazon EFS file system supports one lifecycle configuration, which applies to all files in the file system. If a LifecycleConfiguration object already exists for the specified file system, a PutLifecycleConfiguration call modifies the existing configuration. A PutLifecycleConfiguration call with an empty LifecyclePolicies array in the request body deletes any existing LifecycleConfiguration and disables lifecycle management.

In the request, specify the following:

  • The ID for the file system for which you are enabling, disabling, or modifying lifecycle management.
  • A LifecyclePolicies array of LifecyclePolicy objects that define when files are moved to the IA storage class. The array can contain only one LifecyclePolicy item.

This operation requires permissions for the elasticfilesystem:PutLifecycleConfiguration operation.

To apply a LifecycleConfiguration object to an encrypted file system, you need the same AWS Key Management Service (AWS KMS) permissions as when you created the encrypted file system.

    ]
)
Parameters
  • FileSystemId (string) --

    [REQUIRED]

    The ID of the file system for which you are creating the LifecycleConfiguration object (String).

  • LifecyclePolicies (list) --

    [REQUIRED]

    An array of LifecyclePolicy objects that define the file system's LifecycleConfiguration object. A LifecycleConfiguration object tells lifecycle management when to transition files from the Standard storage class to the Infrequent Access storage class.

    • (dict) --

      Describes a policy used by EFS lifecycle management to transition files to the Infrequent Access (IA) storage class.

      • TransitionToIA (string) --

        A value that describes the period of time that a file is not accessed, after which it transitions to the IA storage class. Metadata operations such as listing the contents of a directory don't count as file access events.

Response Structure

  • (dict) --

    A description of the file system.

    • OwnerId (string) --

      The AWS account that created the file system. If the file system was created by an IAM user, the parent account to which the user belongs is the owner.

    • CreationToken (string) --

      The opaque string specified in the request.

    • FileSystemId (string) --

      The ID of the file system, assigned by Amazon EFS.

    • CreationTime (datetime) --

      The time that the file system was created, in seconds (since 1970-01-01T00:00:00Z).

    • LifeCycleState (string) --

      The lifecycle phase of the file system.

    • Name (string) --

      You can add tags to a file system, including a Name tag. For more information, see CreateFileSystem . If the file system has a Name tag, Amazon EFS returns the value in this field.

    • NumberOfMountTargets (integer) --

      The current number of mount targets that the file system has. For more information, see CreateMountTarget .

    • SizeInBytes (dict) --

      The latest known metered size (in bytes) of data stored in the file system, in its Value field, and the time at which that size was determined in its Timestamp field. The Timestamp value is the integer number of seconds since 1970-01-01T00:00:00Z. The SizeInBytes value doesn't represent the size of a consistent snapshot of the file system, but it is eventually consistent when there are no writes to the file system.

    • FileSystems (list) --

      An array of file system descriptions.

      • (dict) --

        A description of the file system.

        • OwnerId (string) --

          The AWS account that created the file system. If the file system was created by an IAM user, the parent account to which the user belongs is the owner.

        • CreationToken (string) --

          The opaque string specified in the request.

        • FileSystemId (string) --

          The ID of the file system, assigned by Amazon EFS.

        • CreationTime (datetime) --

          The time that the file system was created, in seconds (since 1970-01-01T00:00:00Z).

        • LifeCycleState (string) --

          The lifecycle phase of the file system.

        • Name (string) --

          You can add tags to a file system, including a Name tag. For more information, see CreateFileSystem . If the file system has a Name tag, Amazon EFS returns the value in this field.

        • NumberOfMountTargets (integer) --

          The current number of mount targets that the file system has. For more information, see CreateMountTarget .

        • SizeInBytes (dict) --

          The latest known metered size (in bytes) of data stored in the file system, in its Value field, and the time at which that size was determined in its Timestamp field. The Timestamp value is the integer number of seconds since 1970-01-01T00:00:00Z. The SizeInBytes value doesn't represent the size of a consistent snapshot of the file system, but it is eventually consistent when there are no writes to the file system. That is, SizeInBytes represents actual size only if the file system is not modified for a period longer than a couple of hours. Otherwise, the value is not the exact size that the file system was at any point in time.

          • Value (integer) --

            The latest known metered size (in bytes) of data stored in the file system.

          • Timestamp (datetime) --

            The time at which the size of data, returned in the Value field, was determined. The value is the integer number of seconds since 1970-01-01T00:00:00Z.

          • ValueInIA (integer) --

            The latest known metered size (in bytes) of data stored in the Infrequent Access storage class.

          • ValueInStandard (integer) --

            The latest known metered size (in bytes) of data stored in the Standard storage class.

        • PerformanceMode (string) --

          The performance mode of the file system.

        • Encrypted (boolean) --

          A Boolean value that, if true, indicates that the file system is encrypted.

        • KmsKeyId (string) --

          The ID of an AWS Key Management Service (AWS KMS) customer master key (CMK) that was used to protect the encrypted file system.

        • ThroughputMode (string) --

          The throughput mode for a file system. There are two throughput modes to choose from for your file system: bursting and provisioned . If you set ThroughputMode to provisioned , you must also set a value for ProvisionedThroughPutInMibps . You can decrease your file system's throughput in Provisioned Throughput mode or change between the throughput modes as long as it’s been more than 24 hours since the last decrease or throughput mode change.

        • ProvisionedThroughputInMibps (float) --

          The throughput, measured in MiB/s, that you want to provision for a file system. Valid values are 1-1024. Required if ThroughputMode is set to provisioned . The limit on throughput is 1024 MiB/s. You can get these limits increased by contacting AWS Support. For more information, see Amazon EFS Limits That You Can Increase in the Amazon EFS User Guide.

        • Tags (list) --

          The tags associated with the file system, presented as an array of Tag objects.

          • (dict) --

              The tag key (String). The key can't start with aws: .

            • Value (string) --

              The value of the tag key.

    • NextToken (string) --

      A token to resume pagination.
