EFS / Client / describe_lifecycle_configuration

describe_lifecycle_configuration¶

EFS.Client.describe_lifecycle_configuration(**kwargs)¶

Returns the current LifecycleConfiguration object for the specified EFS file system. Lifecycle management uses the LifecycleConfiguration object to identify when to move files between storage classes. For a file system without a LifecycleConfiguration object, the call returns an empty array in the response.

This operation requires permissions for the elasticfilesystem:DescribeLifecycleConfiguration operation.

Request Syntax

response = client.describe_lifecycle_configuration(
    FileSystemId='string'
)

Parameters:

FileSystemId (string) –

[REQUIRED]

The ID of the file system whose LifecycleConfiguration object you want to retrieve (String).

Return type:

dict

Returns:

Response Structure

(dict) –
- LifecyclePolicies (list) –
  
  An array of lifecycle management policies. EFS supports a maximum of one policy per file system.
  - (dict) –
    
    Describes a policy used by lifecycle management that specifies when to transition files into and out of storage classes. For more information, see Managing file system storage.
    
    Note
    When using the put-lifecycle-configuration CLI command or the PutLifecycleConfiguration API action, Amazon EFS requires that each LifecyclePolicy object have only a single transition. This means that in a request body, LifecyclePolicies must be structured as an array of LifecyclePolicy objects, one object for each transition. For more information, see the request examples in PutLifecycleConfiguration.
    - TransitionToIA (string) –
      
      The number of days after files were last accessed in primary storage (the Standard storage class) at which to move them to Infrequent Access (IA) storage. Metadata operations such as listing the contents of a directory don’t count as file access events.
    - TransitionToPrimaryStorageClass (string) –
      
      Whether to move files back to primary (Standard) storage after they are accessed in IA or Archive storage. Metadata operations such as listing the contents of a directory don’t count as file access events.
    - TransitionToArchive (string) –
      
      The number of days after files were last accessed in primary storage (the Standard storage class) at which to move them to Archive storage. Metadata operations such as listing the contents of a directory don’t count as file access events.

Exceptions

EFS.Client.exceptions.InternalServerError
EFS.Client.exceptions.BadRequest
EFS.Client.exceptions.FileSystemNotFound

Examples

This operation describes a file system’s LifecycleConfiguration. EFS lifecycle management uses the LifecycleConfiguration object to identify which files to move to the EFS Infrequent Access (IA) storage class.

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

print(response)

Expected Output:

{
    'LifecyclePolicies': [
        {
            'TransitionToIA': 'AFTER_30_DAYS',
        },
    ],
    'ResponseMetadata': {
        '...': '...',
    },
