See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  modify-cluster
--cluster-id <value>
[--step-concurrency-level <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--cluster-id (string)

The unique identifier of the cluster.

--step-concurrency-level (integer)

The number of steps that can be executed concurrently. You can specify a minimum of 1 step and a maximum of 256 steps. We recommend that you do not change this parameter while steps are running or the ActionOnFailure setting may not behave as expected. For more information see Step$ActionOnFailure .

--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

StepConcurrencyLevel -> (integer)

The number of steps that can be executed concurrently.
