describe-db-clusters

Description

Returns information about provisioned Aurora DB clusters. This API supports pagination.

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

Note

This operation can also return information for Amazon Neptune DB instances and Amazon DocumentDB instances.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-db-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: DBClusters

Synopsis

  describe-db-clusters
[--db-cluster-identifier <value>]
[--filters <value>]
[--include-shared | --no-include-shared]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--db-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 DB clusters to describe.

Supported filters:

  • db-cluster-id - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs). The results list will only include information about the DB clusters identified by these ARNs.

(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

  • 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", ...]
  }
  ...
]

--include-shared | --no-include-shared (boolean)

Optional Boolean parameter that specifies whether the output includes information about clusters shared from other AWS accounts.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

DBClusters -> (list)

Contains a list of DB clusters for the user.

(structure)

Contains the details of an Amazon Aurora DB cluster.

This data type is used as a response element in the DescribeDBClusters , StopDBCluster , and StartDBCluster actions.

AllocatedStorage -> (integer)

For all database engines except Amazon Aurora, AllocatedStorage specifies the allocated storage size in gibibytes (GiB). For Aurora, AllocatedStorage always returns 1, because Aurora DB cluster storage size isn’t fixed, but instead automatically adjusts as needed.

AvailabilityZones -> (list)

Provides the list of Availability Zones (AZs) where instances in the DB cluster can be created.

(string)

BackupRetentionPeriod -> (integer)

Specifies the number of days for which automatic DB snapshots are retained.

CharacterSetName -> (string)

If present, specifies the name of the character set that this cluster is associated with.

DatabaseName -> (string)

Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster.

DBClusterIdentifier -> (string)

Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster.

DBClusterParameterGroup -> (string)

Specifies the name of the DB cluster parameter group for the DB cluster.

Provides a list of the AWS Identity and Access Management (IAM) roles that are associated with the DB cluster. IAM roles that are associated with a DB cluster grant permission for the DB cluster to access other AWS services on your behalf.

(structure)

Describes an AWS Identity and Access Management (IAM) role that is associated with a DB cluster.

RoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role that is associated with the DB cluster.

Status -> (string)

Describes the state of association between the IAM role and the DB cluster. The Status property returns one of the following values:

  • ACTIVE - the IAM role ARN is associated with the DB cluster and can be used to access other AWS services on your behalf.

  • PENDING - the IAM role ARN is being associated with the DB cluster.

  • INVALID - the IAM role ARN is associated with the DB cluster, but the DB cluster is unable to assume the IAM role in order to access other AWS services on your behalf.

For more information about Aurora Serverless, see Using Amazon Aurora Serverless in the Amazon Aurora User Guide .

EngineMode -> (string)

The DB engine mode of the DB cluster, either provisioned , serverless , parallelquery , global , or multimaster .

Note

global engine mode only applies for global database clusters created with Aurora MySQL version 5.6.10a. For higher Aurora MySQL versions, the clusters in a global database use provisioned engine mode. To check if a DB cluster is part of a global database, use DescribeGlobalClusters instead of checking the EngineMode return value from DescribeDBClusters .
