describe-cluster-tracks

Description

Returns a list of all the available maintenance tracks.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-cluster-tracks 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: MaintenanceTracks

Synopsis

  describe-cluster-tracks
[--maintenance-track-name <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--maintenance-track-name (string)

The name of the maintenance track.

--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 .

--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 .

--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.

See 'aws help' for descriptions of global parameters.

Examples

To describe cluster tracks

The following describe-cluster-tracks example displays details of the available maintenance tracks.

aws redshift describe-cluster-tracks \
    --maintenance-track-name current

Output:

{
    "MaintenanceTracks": [
        {
            "MaintenanceTrackName": "current",

            "UpdateTargets": [
                {
                    "MaintenanceTrackName": "preview_features",

                        }
                    ]

                        },
                        {
                            "OperationName": "modify-cluster"
                        }

Output

MaintenanceTracks -> (list)

A list of maintenance tracks output by the DescribeClusterTracks operation.

(structure)

Defines a maintenance track that determines which Amazon Redshift version to apply during a maintenance window. If the value for MaintenanceTrack is current , the cluster is updated to the most recently certified maintenance release. If the value is trailing , the cluster is updated to the previously certified maintenance release.

MaintenanceTrackName -> (string)

The name of the maintenance track. Possible values are current and trailing .

DatabaseVersion -> (string)

The version number for the cluster release.

UpdateTargets -> (list)

An array of UpdateTarget objects to update with the maintenance track.

(structure)

A maintenance track that you can switch the current track to.

MaintenanceTrackName -> (string)

The name of the new maintenance track.

DatabaseVersion -> (string)

The cluster version for the new maintenance track.

SupportedOperations -> (list)

A list of operations supported by the maintenance track.

(structure)

Describes the operations that are allowed on a maintenance track.

OperationName -> (string)

A list of the supported operations.

Marker -> (string)

The starting point to return a set of response tracklist records. You can retrieve the next set of response records by providing the returned marker value in the Marker parameter and retrying the request.
