2017/03/28 - AWS Batch - 4 updated api methods
Changes Customers can now provide a retryStrategy as part of the RegisterJobDefinition and SubmitJob API calls.
{'jobDefinitions': {'retryStrategy': {'attempts': 'integer'}}}
Describes a list of job definitions. You can specify a status (such as ACTIVE ) to only return job definitions that match that status.

Request Syntax
client.describe_job_definitions(
jobDefinitions=[
'string',
],
maxResults=123,
jobDefinitionName='string',
status='string',
nextToken='string'
)
list
A space-separated list of up to 100 job definition names or full Amazon Resource Name (ARN) entries.
(string) --
integer
The maximum number of results returned by DescribeJobDefinitions in paginated output. When this parameter is used, DescribeJobDefinitions only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeJobDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then DescribeJobDefinitions returns up to 100 results and a nextToken value if applicable.
string
The name of the job definition to describe.
string
The status with which to filter job definitions.
string
The nextToken value returned from a previous paginated DescribeJobDefinitions request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
Note
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

The revision of the job definition.
status (string) --
The status of the job definition.
type (string) --
The type of job definition.
parameters (dict) --
Default parameters or parameter substitution placeholders that are set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.
(string) --
(string) --
retryStrategy (dict) --
The retry strategy to use for failed jobs that are submitted with this job definition.
attempts (integer) --
The number of times to move a job to the RUNNABLE status. You may specify between 1 and 10 attempts. If attempts is greater than one, the job is retried if it fails until it has moved to RUNNABLE that many times.
containerProperties (dict) --
An object with various properties specific to container-based jobs.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with `` repository-url /image :tag `` . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
vcpus (integer) --
The number of vCPUs reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run . Each vCPU is equivalent to 1,024 CPU shares.
memory (integer) --
The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
command (list) --
The command that is passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#cmd .

volumes (list) --
A list of data volumes used in a job.
(dict) --
A data volume used in a job's container properties.

The contents of the host parameter determine whether your data volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.
sourcePath (string) --
The path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .

Warning
We do not recommend using plain text environment variables for sensitive information, such as credential data.

If this value is true , the container has read-only access to the volume; otherwise, the container can write to the volume. The default value is false .
sourceVolume (string) --
The name of the volume to mount.
readonlyRootFilesystem (boolean) --
When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run .
privileged (boolean) --
When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run .
ulimits (list) --
A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run .
(dict) --
The ulimit settings to pass to the container.

The type of the ulimit .
softLimit (integer) --
