describe-global-clusters

Description

Returns information about Aurora global database clusters. This API supports pagination.

For more information on Amazon Aurora, see What is Amazon Aurora? in the Amazon Aurora User Guide .

Note

This action only applies to Aurora DB clusters.

See also: AWS API Documentation

describe-global-clusters 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: GlobalClusters

Options

--global-cluster-identifier (string)

The user-supplied DB cluster identifier. If this parameter is specified, information from only the specific DB cluster is returned. This parameter isn't case-sensitive.

Constraints:

  • If supplied, must match an existing DBClusterIdentifier.

--filters (list)

A filter that specifies one or more global database clusters to describe. This parameter is case-sensitive.

Currently, the only supported filter is region .

If used, the request returns information about any global cluster with at least one member (primary or secondary) in the specified Amazon Web Services Regions.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

Note

Currently, wildcards are not supported in filters.

The following actions can be filtered:

  • DescribeDBClusterBacktracks
  • DescribeDBClusterEndpoints
  • DescribeDBClusters
  • DescribeDBInstances
  • DescribeDBRecommendations
  • DescribeDBShardGroups
  • DescribePendingMaintenanceActions

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

One or more filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--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.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--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.

Examples

Note

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 global DB clusters

The following describe-global-clusters example lists Aurora global DB clusters in the current AWS Region.

Status -> (string)

The current status of the global cluster. Possible values are as follows:

  • pending – The service received a request to switch over or fail over the global cluster. The global cluster's primary DB cluster and the specified secondary DB cluster are being verified before the operation starts.
  • failing-over – Aurora is promoting the chosen secondary Aurora DB cluster to become the new primary DB cluster to fail over the global cluster.
  • cancelling – The request to switch over or fail over the global cluster was cancelled and the primary Aurora DB cluster and the selected secondary Aurora DB cluster are returning to their previous states.
  • switching-over – This status covers the range of Aurora internal operations that take place during the switchover process, such as demoting the primary Aurora DB cluster, promoting the secondary Aurora DB cluster, and synchronizing replicas.
