Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the Amazon Web Services Cloud. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it. For more information, see the Amazon Elastic File System API Reference and the Amazon Elastic File System User Guide.

Sending a Request Using EFS

var efs = new AWS.EFS();
efs.createMountTarget(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the EFS object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var efs = new AWS.EFS({apiVersion: '2015-02-01'});

You can also set the API version globally in AWS.config.apiVersions using the efs service identifier:

AWS.config.apiVersions = {
  efs: '2015-02-01',
  // other service API versions
};

var efs = new AWS.EFS();

Version:

Method Details

createAccessPoint(params = {}, callback) ⇒ AWS.Request

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.

      Specifies the directory on the Amazon 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, EFS creates it and applies the CreationInfo settings when a client connects to an access point. When specifying a RootDirectory, you need to 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.

      • Path — (String)

        Specifies the path on the EFS file system to expose as the root directory to NFS clients using the access point to access the EFS file system. A path can have up to four subdirectories. If the specified path does not exist, you are required to provide the CreationInfo.

      • CreationInfo — (map)

        (Optional) Specifies the POSIX IDs and permissions to apply to the access point's RootDirectory. If the RootDirectory > Path specified does not exist, EFS creates the root directory using the CreationInfo settings when a client connects to an access point. When specifying the CreationInfo, you must provide values for all properties.

        If you do not provide CreationInfo and the specified RootDirectory > Path does not exist, attempts to mount the file system using the access point will fail.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createFileSystem(params = {}, callback) ⇒ AWS.Request

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.

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.

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

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 accepts 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.

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.

});

Parameters:

  • params (Object) (defaults to: {}) —
    • CreationToken — (String)

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

      If a token is not provided, the SDK will use a version 4 UUID.
    • 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.

      Note: The maxIO mode is not supported on file systems using One Zone storage classes.
      Possible values include:
      • "generalPurpose"
      • "maxIO"
    • 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 Key Management Service (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 KMS CMK that you want to use to protect the encrypted file system. This parameter is only required if you want to use a non-default KMS key. 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.

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

    • ThroughputMode — (String)

      Specifies the throughput mode for the file system, either bursting or provisioned. 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 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 information, see Specifying throughput with provisioned mode in the Amazon EFS User Guide.

      Default is bursting.

      Possible values include:
      • "bursting"
      • "provisioned"
    • 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. 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.

    • AvailabilityZoneName — (String)

      Used to create a file system that uses One Zone storage classes. It specifies 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 storage classes, see Using EFS storage classes in the Amazon EFS User Guide.

      Note: One Zone storage classes 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 file system that uses One Zone storage classes, 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.

      Note: Backup is not available in all Amazon Web Services Regionswhere Amazon EFS is available.
    • Tags — (Array<map>)

      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.

      • Key — required — (String)

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

      • Value — required — (String)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • OwnerId — (String)

        The Amazon Web Services 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.

        The Amazon Resource Name (ARN) for the EFS file system, in the format arn:aws:elasticfilesystem:region:account-id:file-system/file-system-id . Example with sample data: arn:aws:elasticfilesystem:us-west-2:1111333322228888:file-system/fs-01234567

      • CreationTime — (Date)

        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.

        Possible values include:

        • "deleted"
        • "error"
      • 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 — (map)

        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.

createMountTarget(params = {}, callback) ⇒ AWS.Request

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 an EFS file system using One Zone storage classes. 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.

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

deleteMountTarget(params = {}, callback) ⇒ AWS.Request

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

describeFileSystems(params = {}, callback) ⇒ AWS.Request

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. 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.

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.

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

This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.

Service Reference:

Examples:

Calling the putFileSystemPolicy operation

var params = {
  FileSystemId: 'STRING_VALUE', /* required */
  Policy: 'STRING_VALUE', /* required */
  BypassPolicyLockoutSafetyCheck: true || false
};
efs.putFileSystemPolicy(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • FileSystemId — (String)

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

    • Policy — (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 EFS Resource-based Policies.

    • BypassPolicyLockoutSafetyCheck — (Boolean)

      (Optional) A flag to indicate whether to bypass the FileSystemPolicy lockout safety check. The policy lockout safety check determines whether the policy in the request will prevent the principal making the request will be locked out from making future PutFileSystemPolicy requests on the file system. Set BypassPolicyLockoutSafetyCheck to True only when you intend to prevent the principal that is making the request from making a subsequent PutFileSystemPolicy request on the file system. The default value is False.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

putLifecycleConfiguration(params = {}, callback) ⇒ AWS.Request

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. To enable EFS Intelligent Tiering, set the value of TransitionToPrimaryStorageClass to AFTER_1_ACCESS. For more information, see EFS Lifecycle Management.

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 turns off lifecycle management for the file system.

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. 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.

Calling the putLifecycleConfiguration operation

var params = {
  FileSystemId: 'STRING_VALUE', /* required */
  LifecyclePolicies: [ /* required */
    {
      TransitionToIA: AFTER_7_DAYS | AFTER_14_DAYS | AFTER_30_DAYS | AFTER_60_DAYS | AFTER_90_DAYS,

  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • FileSystemId — (String)

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

    • LifecyclePolicies — (Array<map>)

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

      • When to move files in the file system from primary storage to the IA storage class.

      • When to move files that are in IA storage to primary 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 needs to be structured as an array of LifecyclePolicy objects, one object for each transition, TransitionToIA, TransitionToPrimaryStorageClass. See the example requests in the following section for more information.
      • TransitionToIA — (String)
