list-release-labels

Description

Retrieves release labels of EMR services in the region where the API is called.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  list-release-labels
[--filters <value>]
[--next-token <value>]
[--max-results <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--filters (structure)

Filters the results of the request. Prefix specifies the prefix of release labels to return. Application specifies the application (with/without version) of release labels to return.

Prefix -> (string)

Optional release label version prefix filter. For example, emr-5 .

Application -> (string)

Optional release label application filter. For example, spark@2.1.0 .

Shorthand Syntax:

Prefix=string,Application=string

JSON Syntax:

{
  "Prefix": "string",
  "Application": "string"
}

--next-token (string)

Specifies the next page of results. If NextToken is not specified, which is usually the case for the first request of ListReleaseLabels, the first page of results are determined by other filtering parameters or by the latest version. The ListReleaseLabels request fails if the identity (Amazon Web Services account ID) and all filtering parameters are different from the original request, or if the NextToken is expired or tampered with.

--max-results (integer)

Defines the maximum number of release labels to return in a single response. The default is 100 .

--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.

--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.

Output

ReleaseLabels -> (list)

The returned release labels.

(string)

NextToken -> (string)

Used to paginate the next page of results if specified in the next ListReleaseLabels request.
