describe-cache-parameter-groups

Description

Returns a list of cache parameter group descriptions. If a cache parameter group name is specified, the list contains only the descriptions for that group.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-cache-parameter-groups 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: CacheParameterGroups

Synopsis

  describe-cache-parameter-groups
[--cache-parameter-group-name <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--cache-parameter-group-name (string)

The name of a specific cache parameter group to return details for.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To describe a cache parameter group

The following describe-cache-parameter-groups example returns a list of cache parameter group descriptions.

aws elasticache describe-cache-parameter-groups \
    --cache-parameter-group-name "mygroup"

Output:

{
    "CacheParameterGroups": [
        {
            "CacheParameterGroupName": "mygroup",
            "CacheParameterGroupFamily": "redis5.0",
            "Description": " "
        }
    ]
}

(structure)

Represents the output of a CreateCacheParameterGroup operation.

CacheParameterGroupName -> (string)

The name of the cache parameter group.

CacheParameterGroupFamily -> (string)

The name of the cache parameter group family that this cache parameter group is compatible with.

Valid values are: memcached1.4 | memcached1.5 | memcached1.6 | redis2.6 | redis2.8 | redis3.2 | redis4.0 | redis5.0 | redis6.x |

Description -> (string)

The description for this cache parameter group.

IsGlobal -> (boolean)

Indicates whether the parameter group is associated with a Global datastore

ARN -> (string)

The ARN (Amazon Resource Name) of the cache parameter group.
