Request Syntax
client.describe_job_definitions(
jobDefinitions=[
'string',
],
maxResults=123,
jobDefinitionName='string',
status='string',
nextToken='string'
)
list
A 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.

If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, 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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location 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 .
environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run .
Warning
We do not recommend using plaintext environment variables for sensitive information, such as credential data.
Note
Environment variables must not start with AWS_BATCH ; this naming convention is reserved for variables that are set by the AWS Batch service.
(dict) --
A key-value pair object.
name (string) --
The name of the key-value pair. For environment variables, this is the name of the environment variable.
value (string) --
The value of the key-value pair. For environment variables, this is the value of the environment variable.
mountPoints (list) --
The mount points for data volumes in your container. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run .
(dict) --
Details on a Docker volume mount point that is used in a job's container properties. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.
containerPath (string) --
The path on the container at which to mount the host volume.
readOnly (boolean) --
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.
hardLimit (integer) -- [REQUIRED]
The hard limit for the ulimit type.
name (string) -- [REQUIRED]
The type of the ulimit .
softLimit (integer) -- [REQUIRED]
The soft limit for the ulimit type.
user (string) --
The user name to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run .
instanceType (string) --
The instance type to use for a multi-node parallel job. Currently all node groups in a multi-node parallel job must use the same instance type. This parameter is not valid for single-node container jobs.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. Currently, the only supported resource is GPU .
(dict) --
The type and amount of a resource to assign to a container. Currently, the only supported resource type is GPU .
value (string) -- [REQUIRED]
The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job should not exceed the number of available GPUs on the compute resource that the job is launched on.
type (string) -- [REQUIRED]
The type of resource to assign to a container. Currently, the only supported resource type is GPU .
linuxParameters (dict) --
Linux-specific modifications that are applied to the container, such as Linux kernel capabilities.
devices (list) --
Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run .
(dict) --
An object representing a container instance host device.
hostPath (string) -- [REQUIRED]
The path for the device on the host container instance.
containerPath (string) --
The path inside the container at which to expose the host device.
permissions (list) --
The explicit permissions to provide to the container for the device. By default, the container has permissions for read , write , and mknod for the device.
(string) --
dict
The retry strategy to use for failed jobs that are submitted with this job definition. Any retry strategy that is specified during a SubmitJob operation overrides the retry strategy defined here. If a job is terminated due to a timeout, it is not retried.
attempts (integer) --
The number of times to move a job to the RUNNABLE status. You may specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.
dict
The timeout configuration for jobs that are submitted with this job definition, after which AWS Batch terminates your jobs if they have not finished. If a job is terminated due to a timeout, it is not retried. The minimum value for the timeout is 60 seconds. Any timeout configuration that is specified during a SubmitJob operation overrides the timeout configuration defined here. For more information, see Job Timeouts in the Amazon Elastic Container Service Developer Guide .
attemptDurationSeconds (integer) --
The time duration in seconds (measured from the job attempt's startedAt timestamp) after which AWS Batch terminates your jobs if they have not finished.
