SDK for PHP 3.x

Client: Aws\Efs\EfsClient
Service ID: elasticfilesystem
Version: 2015-02-01

This page describes the parameters and results for the operations of the Amazon Elastic File System (2015-02-01), and shows how to use the Aws\Efs\EfsClient object to call the described operations. This documentation is specific to the 2015-02-01 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Operations

CreateAccessPoint

$result = $client->createAccessPoint([/* ... */]);
$promise = $client->createAccessPointAsync([/* ... */]);

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. 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 1,000 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.

Parameter Syntax

$result = $client->createAccessPoint([
    'ClientToken' => '<string>', // REQUIRED
    'FileSystemId' => '<string>', // REQUIRED
    'PosixUser' => [
        'Gid' => <integer>, // REQUIRED

        'CreationInfo' => [
            'OwnerGid' => <integer>, // REQUIRED
            'OwnerUid' => <integer>, // REQUIRED
            'Permissions' => '<string>', // REQUIRED
        ],

]);

Parameter Details

Members
ClientToken
Required: Yes
Type: string

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

FileSystemId
Required: Yes
Type: string

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

PosixUser
Type: PosixUser structure

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

RootDirectory
Type: RootDirectory structure

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.

Tags
Type: Array of Tag structures

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.

Errors

BadRequest:

Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

AccessPointAlreadyExists:

Returned if the access point that you are trying to create already exists, with the creation token you provided in the request.

IncorrectFileSystemLifeCycleState:

Returned if the file system's lifecycle state is not "available".

InternalServerError:

Returned if an error occurred on the server side.

FileSystemNotFound:

Returned if the specified FileSystemId value doesn't exist in the requester's Amazon Web Services account.

AccessPointLimitExceeded:

Returned if the Amazon Web Services account has already created the maximum number of access points allowed per file system. For more informaton, see https://docs.aws.amazon.com/efs/latest/ug/limits.html#limits-efs-resources-per-account-per-region.

ThrottlingException:

Returned when the CreateAccessPoint API action is called too quickly and the number of Access Points on the file system is nearing the limit of 120.

CreateFileSystem

$result = $client->createFileSystem([/* ... */]);
$promise = $client->createFileSystemAsync([/* ... */]);

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.

]);

Parameter Details

Members
AvailabilityZoneName
Type: 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
Type: 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.

CreationToken
Required: Yes
Type: string

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

Encrypted
Type: 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.

KmsKeyId
Type: 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.

PerformanceMode
Type: 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.

ProvisionedThroughputInMibps
Type: double

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 Services Support. For more information, see Amazon EFS quotas that you can increase in the Amazon EFS User Guide.

Tags
Type: Array of Tag structures

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.

ThroughputMode
Type: 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.

        ],
    ],
]

CreateMountTarget

$result = $client->createMountTarget([/* ... */]);
$promise = $client->createMountTargetAsync([/* ... */]);

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. 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

DeleteFileSystem

$result = $client->deleteFileSystem([/* ... */]);
$promise = $client->deleteFileSystemAsync([/* ... */]);

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.

DeleteMountTarget

$result = $client->deleteMountTarget([/* ... */]);
$promise = $client->deleteMountTargetAsync([/* ... */]);

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

Parameter Syntax

$result = $client->deleteMountTarget([

DeleteReplicationConfiguration

$result = $client->deleteReplicationConfiguration([/* ... */]);
$promise = $client->deleteReplicationConfigurationAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->deleteReplicationConfiguration([
    'DeletionMode' => 'ALL_CONFIGURATIONS|LOCAL_CONFIGURATION_ONLY',
    'SourceFileSystemId' => '<string>', // REQUIRED
]);

Parameter Details

Members
DeletionMode
Type: 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.

SourceFileSystemId
Required: Yes
Type: string

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

DeleteTags

$result = $client->deleteTags([/* ... */]);
$promise = $client->deleteTagsAsync([/* ... */]);

DEPRECATED - DeleteTags is deprecated and not maintained. To remove tags from EFS resources, use the API action.

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 Billing and Cost Management User Guide.

This operation requires permissions for the elasticfilesystem:DeleteTags action.

DescribeFileSystems

$result = $client->describeFileSystems([/* ... */]);
$promise = $client->describeFileSystemsAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->describeFileSystems([

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.

Parameter Syntax

IncorrectFileSystemLifeCycleState:

Returned if the file system's lifecycle state is not "available".

PutLifecycleConfiguration

$result = $client->putLifecycleConfiguration([/* ... */]);
$promise = $client->putLifecycleConfigurationAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->putLifecycleConfiguration([
    'FileSystemId' => '<string>', // REQUIRED
    'LifecyclePolicies' => [ // REQUIRED
        [
            'TransitionToArchive' => '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',

        ],
        // ...
    ],
]);

Parameter Details

Members
FileSystemId
Required: Yes
Type: string

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

LifecyclePolicies
Required: Yes
Type: Array of LifecyclePolicy structures

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.

Result Syntax

[
    'LifecyclePolicies' => [
        [

DestinationToCreate

Description

Describes the new or existing destination file system for the replication configuration.

  • If you want to replicate to a new file system, do not specify the File System ID for the destination file system. Amazon EFS creates a new, empty file system. For One Zone storage, specify the Availability Zone to create the file system in. To use an Key Management Service key other than the default KMS key, then specify it. For more information, see Configuring replication to new Amazon EFS file system in the Amazon EFS User Guide.

    After the file system is created, you cannot change the KMS key or the performance mode.

  • If you want to replicate to an existing file system that's in the same account as the source file system, then you need to provide the ID or Amazon Resource Name (ARN) of the file system to which to replicate. The file system's replication overwrite protection must be disabled. For more information, see Replicating to an existing file system in the Amazon EFS User Guide.

  • If you are replicating the file system to a file system that's in a different account than the source file system (cross-account replication), you need to provide the ARN for the file system and the IAM role that allows Amazon EFS to perform replication on the destination account. The file system's replication overwrite protection must be disabled. For more information, see Replicating across Amazon Web Services accounts in the Amazon EFS User Guide.
