[ aws . efs ]



Returns the descriptions of all the current mount targets, or a specific mount target, for a file system. When requesting all of the current mount targets, the order of mount targets returned in the response is unspecified.

This operation requires permissions for the elasticfilesystem:DescribeMountTargets action, on either the file system ID that you specify in FileSystemId , or on the file system of the mount target that you specify in MountTargetId .

See also: AWS API Documentation

describe-mount-targets is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: MountTargets


[--max-items <value>]
[--file-system-id <value>]
[--mount-target-id <value>]
[--access-point-id <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]


--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--file-system-id (string)

(Optional) ID of the file system whose mount targets you want to list (String). It must be included in your request if an AccessPointId or MountTargetId is not included. Accepts either a file system ID or ARN as input.

--mount-target-id (string)

(Optional) ID of the mount target that you want to have described (String). It must be included in your request if FileSystemId is not included. Accepts either a mount target ID or ARN as input.

--access-point-id (string)

(Optional) The ID of the access point whose mount targets that you want to list. It must be included in your request if a FileSystemId or MountTargetId is not included in your request. Accepts either an access point ID or ARN as input.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe a mount target

The following describe-mount-targets example describes the specified mount target.

aws efs describe-mount-targets \
    --mount-target-id fsmt-f9a14450


    "MountTargets": [
            "OwnerId": "123456789012",
            "MountTargetId": "fsmt-f9a14450",
            "FileSystemId": "fs-c7a0456e",
            "SubnetId": "subnet-02bf4c428bexample",
            "LifeCycleState": "creating",
            "IpAddress": "",
            "NetworkInterfaceId": "eni-02d542216aexample",
            "AvailabilityZoneId": "use2-az2",
            "AvailabilityZoneName": "us-east-2b",
            "VpcId": "vpc-0123456789abcdef0"

For more information, see Creating mount targets in the Amazon Elastic File System User Guide.


Marker -> (string)

If the request included the Marker , the response returns that value in this field.

MountTargets -> (list)

Returns the file system's mount targets as an array of MountTargetDescription objects.


Provides a description of a mount target.

OwnerId -> (string)

Amazon Web Services account ID that owns the resource.

MountTargetId -> (string)

System-assigned mount target ID.

FileSystemId -> (string)

The ID of the file system for which the mount target is intended.

SubnetId -> (string)

The ID of the mount target's subnet.

LifeCycleState -> (string)

Lifecycle state of the mount target.

IpAddress -> (string)

Address at which the file system can be mounted by using the mount target.

NetworkInterfaceId -> (string)

The ID of the network interface that Amazon EFS created when it created the mount target.

AvailabilityZoneId -> (string)

The unique and consistent identifier of the Availability Zone that the mount target resides in. For example, use1-az1 is an AZ ID for the us-east-1 Region and it has the same location in every Amazon Web Services account.

AvailabilityZoneName -> (string)

The name of the Availability Zone in which the mount target is located. Availability Zones are independently mapped to names for each Amazon Web Services account. For example, the Availability Zone us-east-1a for your Amazon Web Services account might not be the same location as us-east-1a for another Amazon Web Services account.

VpcId -> (string)

The virtual private cloud (VPC) ID that the mount target is configured in.

NextMarker -> (string)

If a value is present, there are more mount targets to return. In a subsequent request, you can provide Marker in your request with this value to retrieve the next set of mount targets.
