[ 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 file-system-id , or on the file system of the mount target that you specify in mount-target-id .

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>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--generate-cli-skeleton <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 mount-target-id is not included.

--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 file-system-id is not included.

--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.

--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.


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)

AWS account ID that owns the resource.

MountTargetId -> (string)

System-assigned mount target ID.

FileSystemId -> (string)

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

SubnetId -> (string)

ID of the mount target's subnet.

LifeCycleState -> (string)

Lifecycle state of the mount target.

IpAddress -> (string)

Address at which the file system may be mounted via the mount target.

NetworkInterfaceId -> (string)

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

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.
