Description

Describes one or more of your scheduling policies.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-scheduling-policies
--arns <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--arns (list)

A list of up to 100 scheduling policy Amazon Resource Name (ARN) entries.

(string)

Syntax:

"string" "string" ...

--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.

See ‘aws help’ for descriptions of global parameters.

Output

schedulingPolicies -> (list)

The list of scheduling policies.

(structure)

An object that represents a scheduling policy.

name -> (string)

The name of the scheduling policy.

arn -> (string)

The Amazon Resource Name (ARN) of the scheduling policy. An example is ``arn:aws :batch:us-east-1 :123456789012 :scheduling-policy/HighPriority `` .

fairsharePolicy -> (structure)

The fair share policy for the scheduling policy.

shareDecaySeconds -> (integer)

The time period to use to calculate a fair share percentage for each fair share identifier in use, in seconds. A value of zero (0) indicates that only current usage should be measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).

computeReservation -> (integer)

A value used to reserve some of the available maximum vCPU for fair share identifiers that have not yet been used.

The reserved ratio is ``(computeReservation /100)^*ActiveFairShares* `` where `` ActiveFairShares `` is the number of active fair share identifiers.

For example, a computeReservation value of 50 indicates that Batch should reserve 50% of the maximum available vCPU if there is only one fair share identifier, 25% if there are two fair share identifiers, and 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there is only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.

The minimum value is 0 and the maximum value is 99.

shareDistribution -> (list)

An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren’t included have a default weight of 1.0 .

(structure)

Specifies the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren’t included have a default weight of 1.0 .

shareIdentifier -> (string)

A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (*), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy cannot overlap. For example, you can’t have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1 .

There can be no more than 500 fair share identifiers active in a job queue.

The string is limited to 255 alphanumeric characters, optionally followed by an asterisk (*).

weightFactor -> (float)

The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.

The smallest supported value is 0.0001, and the largest supported value is 999.9999.

tags -> (map)

The tags that you apply to the scheduling policy to categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services resources in Amazon Web Services General Reference .

key -> (string)

value -> (string)
