Shorthand Syntax:

id=string,version=string

JSON Syntax:

{
  "id": "string",

}

--purchase-option (string)

Specifies how EC2 instances are purchased on your behalf. Amazon Web Services PCS supports On-Demand and Spot instances. For more information, see Instance purchasing options in the Amazon Elastic Compute Cloud User Guide . If you don’t provide this option, it defaults to On-Demand.

Possible values:

  • ONDEMAND
  • SPOT

--spot-options (structure)

Additional configuration when you specify SPOT as the purchaseOption for the CreateComputeNodeGroup API action.

allocationStrategy -> (string)

The Amazon EC2 allocation strategy Amazon Web Services PCS uses to provision EC2 instances. Amazon Web Services PCS supports lowest price , capacity optimized , and price capacity optimized . For more information, see Use allocation strategies to determine how EC2 Fleet or Spot Fleet fulfills Spot and On-Demand capacity in the Amazon Elastic Compute Cloud User Guide . If you don’t provide this option, it defaults to price capacity optimized .

Shorthand Syntax:

allocationStrategy=string

JSON Syntax:

{
  "allocationStrategy": "lowest-price"|"capacity-optimized"|"price-capacity-optimized"
}

  "minInstanceCount": integer,

}

--iam-instance-profile-arn (string)

The Amazon Resource Name (ARN) of the IAM instance profile used to pass an IAM role when launching EC2 instances. The role contained in your instance profile must have the pcs:RegisterComputeNodeGroupInstance permission. The resource identifier of the ARN must start with AWSPCS or it must have /aws-pcs/ in its path.

Examples
  • arn:aws:iam::111122223333:instance-profile/AWSPCS-example-role-1
  • arn:aws:iam::111122223333:instance-profile/aws-pcs/example-role-2

--slurm-configuration (structure)

Additional options related to the Slurm scheduler.

slurmCustomSettings -> (list)

Additional Slurm-specific configuration that directly maps to Slurm settings.

(structure)

Additional settings that directly map to Slurm settings.

parameterName -> (string)

Amazon Web Services PCS supports configuration of the following Slurm parameters:

parameterValue -> (string)

The values for the configured Slurm settings.

Shorthand Syntax:

slurmCustomSettings=[{parameterName=string,parameterValue=string},{parameterName=string,parameterValue=string}]

JSON Syntax:

{
  "slurmCustomSettings": [
    {
      "parameterName": "string",
      "parameterValue": "string"
    }
    ...
  ]
}

--client-token (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully, the subsequent retries with the same client token return the result from the original successful request and they have no additional effect. If you don’t specify a client token, the CLI and SDK automatically generate 1 for you.

--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.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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
  • yaml
  • yaml-stream

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.
