Overview

An API client for EFS. To construct a client, you need to configure a :region and :credentials.

client = Aws::EFS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]
    • The :access_key_id, :secret_access_key, :session_token, and :account_id options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID']
    • ~/.aws/credentials
    • ~/.aws/config
    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentials or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.
  • :region (required, String) —

Instance Method Details

#create_access_point(params = {}) ⇒ Types::AccessPointDescription

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 the application's own directory and any subdirectories. A file system can have a maximum of 10,000 access points unless you request an increase. To learn more, see Mounting a file system using EFS access points.

If multiple requests to create access points on the same file system are sent in quick succession, and the file system is near the limit of access points, you may experience a throttling response for these requests. This is to ensure that the file system does not exceed the stated access point limit.

This operation requires permissions for the elasticfilesystem:CreateAccessPoint action.

Access points can be tagged on creation. If tags are specified in the creation action, IAM performs additional authorization on the elasticfilesystem:TagResource action to verify if users have permissions to create tags. Therefore, you must grant explicit permissions to use the elasticfilesystem:TagResource action. For more information, see Granting permissions to tag resources during creation.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :client_token (required, String) —

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

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :tags (Array<Types::Tag>) —

    Creates tags associated with the access point. Each tag is a key-value pair, each key must be unique. For more information, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference Guide.

  • :file_system_id (required, String) —

    The ID of the EFS file system that the access point provides access to.

  • :posix_user (Types::PosixUser) —

    The operating system user and group applied to all file system requests made using the access point.

  • :root_directory (Types::RootDirectory) —

    Specifies the directory on the EFS file system that the access point exposes as the root directory of your file system to NFS clients using the access point. The clients using the access point can only access the root directory and below. If the RootDirectory > Path specified does not exist, Amazon EFS creates it and applies the CreationInfo settings when a client connects to an access point. When specifying a RootDirectory, you must provide the Path, and the CreationInfo.

    Amazon EFS creates a root directory only if you have provided the CreationInfo: OwnUid, OwnGID, and permissions for the directory. If you do not provide this information, Amazon EFS does not create the root directory. If the root directory does not exist, attempts to mount using the access point will fail.

Returns:

#create_file_system(params = {}) ⇒ Types::FileSystemDescription

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 Amazon Web Services 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.

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.

For more information, see Creating a file system in the Amazon EFS User Guide.

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 accepts an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose PerformanceMode for all file systems. The maxIO mode is a previous generation performance type that is designed for highly parallelized workloads that can tolerate higher latencies than the generalPurpose mode. MaxIO mode is not supported for One Zone file systems or file systems that use Elastic throughput.

The PerformanceMode can't be changed after the file system has been created. For more information, see Amazon EFS performance modes.

You can set the throughput mode for the file system using the ThroughputMode parameter.

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.

File systems can be tagged on creation. If tags are specified in the creation action, IAM performs additional authorization on the elasticfilesystem:TagResource action to verify if users have permissions to create tags. Therefore, you must grant explicit permissions to use the elasticfilesystem:TagResource action. For more information, see Granting permissions to tag resources during creation.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :creation_token (required, String) —

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

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :performance_mode (String) —

    The performance mode of the file system. We recommend generalPurpose performance mode for all 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. The maxIO mode is not supported on One Zone file systems.

    Due to the higher per-operation latencies with Max I/O, we recommend using General Purpose performance mode for all file systems.

    Default is generalPurpose.

  • :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 an existing Key Management Service key (KMS key). If you don't specify a KMS key, then the default KMS key for Amazon EFS, /aws/elasticfilesystem, is used to protect the encrypted file system.

  • :kms_key_id (String) —

    The ID of the KMS key that you want to use to protect the encrypted file system. This parameter is required only if you want to use a non-default KMS key. If this parameter is not specified, the default KMS key for Amazon EFS is used. You can specify a KMS key ID using 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 you use KmsKeyId, you must set the CreateFileSystemRequest$Encrypted parameter to true.

    EFS accepts only symmetric KMS keys. You cannot use asymmetric KMS keys with Amazon EFS file systems.

  • :throughput_mode (String) —

    Specifies the throughput mode for the file system. The mode can be bursting, provisioned, or elastic. If you set ThroughputMode to provisioned, you must also set a value for ProvisionedThroughputInMibps. After you create the file system, you can decrease your file system's Provisioned throughput or change between the throughput modes, with certain time restrictions. For more information, see Specifying throughput with provisioned mode in the Amazon EFS User Guide.

    Default is bursting.

  • :provisioned_throughput_in_mibps (Float) —

    The throughput, measured in mebibytes per second (MiBps), that you want to provision for a file system that you're creating. Required if ThroughputMode is set to provisioned. Valid values are 1-3414 MiBps, with the upper limit depending on Region. To increase this limit, contact Amazon Web ServicesSupport. For more information, see Amazon EFS quotas that you can increase in the Amazon EFS User Guide.

  • :availability_zone_name (String) —

    For One Zone file systems, specify the Amazon Web Services Availability Zone in which to create the file system. Use the format us-east-1a to specify the Availability Zone. For more information about One Zone file systems, see EFS file system types in the Amazon EFS User Guide.

    One Zone file systems are not available in all Availability Zones in Amazon Web Services Regions where Amazon EFS is available.

  • :backup (Boolean) —

    Specifies whether automatic backups are enabled on the file system that you are creating. Set the value to true to enable automatic backups. If you are creating a One Zone file system, automatic backups are enabled by default. For more information, see Automatic backups in the Amazon EFS User Guide.

    Default is false. However, if you specify an AvailabilityZoneName, the default is true.

    Backup is not available in all Amazon Web Services Regions where Amazon EFS is available.

  • :tags (Array<Types::Tag>) —

    Use 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. Each key must be unique. For more information, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference Guide.

#create_mount_target(params = {}) ⇒ Types::MountTargetDescription

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.

You can create only one mount target for a One Zone file system. You must create that mount target in the same Availability Zone in which the file system is located. Use the AvailabilityZoneName and AvailabiltyZoneId properties in the DescribeFileSystems response object to get this information. Use the subnetId associated with the file system's Availability Zone when creating the mount target.

For more information, see Amazon EFS: How it Works.

To create a mount target for a file system, the file system's lifecycle state must be available. For more information, see DescribeFileSystems.

In the request, provide the following:

  • The file system ID for which you are creating the mount target.

  • A subnet ID, which determines the following:

    • The VPC in which Amazon EFS creates the mount target

    • The Availability Zone in which Amazon EFS creates the mount target

    • The 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.

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 pricing. 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_replication_configuration(params = {}) ⇒ Types::ReplicationConfigurationDescription

Creates a replication configuration to either a new or existing EFS file system. For more information, see Amazon EFS replication in the Amazon EFS User Guide. The replication configuration specifies the following:

  • Source file system – The EFS file system that you want to replicate.

  • Destination file system – The destination file system to which the source file system is replicated. There can only be one destination file system in a replication configuration.

    A file system can be part of only one replication configuration.

    The destination parameters for the replication configuration depend on whether you are replicating to a new file system or to an existing file system, and if you are replicating across Amazon Web Services accounts. See DestinationToCreate for more information.

This operation requires permissions for the elasticfilesystem:CreateReplicationConfiguration action. Additionally, other permissions are required depending on how you are replicating file systems. For more information, see Required permissions for replication in the Amazon EFS User Guide.

#create_tags(params = {}) ⇒ Struct

DEPRECATED - CreateTags is deprecated and not maintained. To create tags for EFS resources, use the API action.

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.

Examples:

Example: To create a new tag


# This operation creates a new tag for an EFS file system.

resp = client.create_tags({
  file_system_id: "fs-01234567", 
  tags: [

end

#delete_file_system(params = {}) ⇒ Struct

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 need to manually delete mount targets attached to a file system before you can delete an EFS file system. This step is performed for you when you use the Amazon Web Services console to delete a file system.

You cannot delete a file system that is part of an EFS replication configuration. You need to delete the replication configuration first.

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.

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.

Examples:

Example: To delete a file system


# This operation deletes an EFS file system.

resp = client.delete_file_system({

#delete_mount_target(params = {}) ⇒ Struct

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

^

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

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :mount_target_id (required, String) —

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

#delete_replication_configuration(params = {}) ⇒ Struct

Deletes a replication configuration. Deleting a replication configuration ends the replication process. After a replication configuration is deleted, the destination file system becomes Writeable and its replication overwrite protection is re-enabled. For more information, see Delete a replication configuration.

This operation requires permissions for the elasticfilesystem:DeleteReplicationConfiguration action.

Examples:

Request syntax with placeholder values


resp = client.delete_replication_configuration({
  source_file_system_id: "FileSystemId", # required
  deletion_mode: "ALL_CONFIGURATIONS", # accepts ALL_CONFIGURATIONS, LOCAL_CONFIGURATION_ONLY
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :source_file_system_id (required, String) —

    The ID of the source file system in the replication configuration.

  • :deletion_mode (String) —

    When replicating across Amazon Web Services accounts or across Amazon Web Services Regions, Amazon EFS deletes the replication configuration from both the source and destination account or Region (ALL_CONFIGURATIONS) by default. If there's a configuration or permissions issue that prevents Amazon EFS from deleting the replication configuration from both sides, you can use the LOCAL_CONFIGURATION_ONLY mode to delete the replication configuration from only the local side (the account or Region from which the delete is performed).

    Only use the LOCAL_CONFIGURATION_ONLY mode in the case that Amazon EFS is unable to delete the replication configuration in both the source and destination account or Region. Deleting the local configuration leaves the configuration in the other account or Region unrecoverable.

    Additionally, do not use this mode for same-account, same-region replication as doing so results in a BadRequest exception error.

Returns:

  • (Struct) —

    Returns an empty response.

#describe_file_systems(params = {}) ⇒ Types::DescribeFileSystemsResponse

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 Amazon Web Services account in the Amazon Web Services 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. This number is automatically set to 100. 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.

The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.

Examples:

Example: To describe an EFS file system


# This operation describes all of the EFS file systems in an account.

resp = client.describe_file_systems({
})

resp.to_h outputs the following:
{
  file_systems: [

#put_account_preferences(params = {}) ⇒ Types::PutAccountPreferencesResponse

Use this operation to set the account preference in the current Amazon Web Services Region to use long 17 character (63 bit) or short 8 character (32 bit) resource IDs for new EFS file system and mount target resources. All existing resource IDs are not affected by any changes you make. You can set the ID preference during the opt-in period as EFS transitions to long resource IDs. For more information, see Managing Amazon EFS resource IDs.

Starting in October, 2021, you will receive an error if you try to set the account preference to use the short 8 character format resource ID. Contact Amazon Web Services support if you receive an error and must use short IDs for file system and mount target resources.

Examples:

Request syntax with placeholder values


resp = client.({
  resource_id_type: "LONG_ID", # required, accepts LONG_ID, SHORT_ID

#put_file_system_policy(params = {}) ⇒ Types::FileSystemPolicyDescription

Applies an Amazon EFS FileSystemPolicy to an Amazon EFS file system. A file system policy is an IAM resource-based policy and can contain multiple policy statements. 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. EFS file system policies have a 20,000 character limit. 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.

EFS file system policies have a 20,000 character limit.

This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.

Examples:

Request syntax with placeholder values


resp = client.put_file_system_policy({
  file_system_id: "FileSystemId", # required
  policy: "Policy", # required
  bypass_policy_lockout_safety_check: false,
})

Response structure


resp.file_system_id #=> String
resp.policy #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :file_system_id (required, String) —

    The ID of the EFS file system that you want to create or update the FileSystemPolicy for.

  • :policy (required, String) —

    The FileSystemPolicy that you're creating. Accepts a JSON formatted policy definition. EFS file system policies have a 20,000 character limit. To find out more about the elements that make up a file system policy, see Resource-based policies within Amazon EFS.

  • :bypass_policy_lockout_safety_check (Boolean) — default: Optional —

    A boolean that specifies whether or not to bypass the FileSystemPolicy lockout safety check. The lockout safety check determines whether the policy in the request will lock out, or prevent, the IAM principal that is making the request from making future PutFileSystemPolicy requests on this file system. Set BypassPolicyLockoutSafetyCheck to True only when you intend to prevent the IAM principal that is making the request from making subsequent PutFileSystemPolicy requests on this file system. The default value is False.

Returns:

#put_lifecycle_configuration(params = {}) ⇒ Types::LifecycleConfigurationDescription

Use this action to manage storage for your file system. A LifecycleConfiguration consists of one or more LifecyclePolicy objects that define the following:

  • TransitionToIA – When to move files in the file system from primary storage (Standard storage class) into the Infrequent Access (IA) storage.

  • TransitionToArchive – When to move files in the file system from their current storage class (either IA or Standard storage) into the Archive storage.

    File systems cannot transition into Archive storage before transitioning into IA storage. Therefore, TransitionToArchive must either not be set or must be later than TransitionToIA.

    The Archive storage class is available only for file systems that use the Elastic throughput mode and the General Purpose performance mode.

    ^

  • TransitionToPrimaryStorageClass – Whether to move files in the file system back to primary storage (Standard storage class) after they are accessed in IA or Archive storage.

^

For more information, see Managing file system storage.

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. 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 to move files to IA storage, to Archive storage, and back to primary storage.

    Amazon EFS requires that each LifecyclePolicy object have only have a single transition, so the LifecyclePolicies array needs to be structured with separate LifecyclePolicy objects. See the example requests in the following section for more information.

This operation requires permissions for the elasticfilesystem:PutLifecycleConfiguration operation.

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

Examples:

Example: Creates a new lifecycleconfiguration object for a file system


# This operation enables lifecycle management on a file system 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.

resp = client.put_lifecycle_configuration({
  file_system_id: "fs-01234567", 
  lifecycle_policies: [
    {
      transition_to_ia: "AFTER_30_DAYS", 
    }, 
  ], 
})

resp.to_h outputs the following:
{
  lifecycle_policies: [
    {
      transition_to_ia: "AFTER_30_DAYS", 
    }, 
  ], 
}

Request syntax with placeholder values

      transition_to_primary_storage_class: "AFTER_1_ACCESS", # accepts AFTER_1_ACCESS
      transition_to_archive: "AFTER_1_DAY", # accepts AFTER_1_DAY, AFTER_7_DAYS, AFTER_14_DAYS, AFTER_30_DAYS, AFTER_60_DAYS, AFTER_90_DAYS, AFTER_180_DAYS, AFTER_270_DAYS, AFTER_365_DAYS
    },
  ],
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :file_system_id (required, String) —

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

  • :lifecycle_policies (required, Array<Types::LifecyclePolicy>) —

    An array of LifecyclePolicy objects that define the file system's LifecycleConfiguration object. A LifecycleConfiguration object informs lifecycle management of the following:

    • TransitionToIA – When to move files in the file system from primary storage (Standard storage class) into the Infrequent Access (IA) storage.

    • TransitionToArchive – When to move files in the file system from their current storage class (either IA or Standard storage) into the Archive storage.

      File systems cannot transition into Archive storage before transitioning into IA storage. Therefore, TransitionToArchive must either not be set or must be later than TransitionToIA.

      The Archive storage class is available only for file systems that use the Elastic throughput mode and the General Purpose performance mode.

    • TransitionToPrimaryStorageClass – Whether to move files in the file system back to primary storage (Standard storage class) after they are accessed in IA or Archive storage.

    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 storage transition. See the example requests in the following section for more information.
