    :type jobDefinitionName: string
    :param jobDefinitionName: [REQUIRED]
            The name of the job definition to register.
            

    :type type: string
    :param type: [REQUIRED]
            The type of job definition.
            

    :type parameters: dict
    :param parameters: Default parameter substitution placeholders to 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) --
            

    :type containerProperties: dict
    :param containerProperties: An object with various properties specific for container-based jobs. This parameter is required if the type parameter is container .
            image (string) -- [REQUIRED]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) -- [REQUIRED]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) -- [REQUIRED]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 .
            (string) --
            jobRoleArn (string) --The Amazon Resource Name (ARN) of the IAM role that the container can assume for AWS permissions.
            volumes (list) --A list of data volumes used in a job.
            (dict) --A data volume used in a job's container properties.
            host (dict) --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 .
            
            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 plain text environment variables for sensitive information, such as credential data.
            (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.
            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 .
            

    :type retryStrategy: dict
    :param retryStrategy: 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.
            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.
