containerInstanceArn (string) --
The Amazon Resource Name (ARN) of the Amazon ECS container instance that hosts the job attempt.
taskArn (string) --
The Amazon Resource Name (ARN) of the Amazon ECS task that is associated with the job attempt. Each container attempt receives a task ARN when they reach the STARTING status.
exitCode (integer) --
The exit code for the job attempt. A non-zero exit code is considered a failure.
reason (string) --
A short (255 max characters) human-readable string to provide additional details about a running or stopped container.
logStreamName (string) --
The name of the CloudWatch Logs log stream associated with the container. The log group for AWS Batch jobs is /aws/batch/job. Each container attempt receives a log stream name when they reach the RUNNING status.
startedAt (integer) --
The Unix time stamp for when the attempt was started (when the attempt transitioned from the STARTING state to the RUNNING state).
stoppedAt (integer) --
The Unix time stamp for when the attempt was stopped (when the attempt transitioned from the RUNNING state to a terminal state, such as SUCCEEDED or FAILED).
statusReason (string) --
A short, human-readable string to provide additional details about the current status of the job attempt.
statusReason (string) --
A short, human-readable string to provide additional details about the current status of the job.
createdAt (integer) --
The Unix time stamp for when the job was created. For non-array jobs and parent array jobs, this is when the job entered the SUBMITTED state (at the time SubmitJob was called). For array child jobs, this is when the child job was spawned by its parent and entered the PENDING state.
retryStrategy (dict) --
The retry strategy to use for this job if an attempt fails.
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 if it fails until it has moved to RUNNABLE that many times.

A list of volumes associated with the 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. 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 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.

client.list_jobs(
jobQueue='string',
arrayJobId='string',
jobStatus='SUBMITTED'|'PENDING'|'RUNNABLE'|'STARTING'|'RUNNING'|'SUCCEEDED'|'FAILED',
maxResults=123,
nextToken='string'
)
string
The name or full Amazon Resource Name (ARN) of the job queue with which to list jobs.
string
The job ID for an array job. Specifying an array job ID with this parameter lists all child jobs from within the specified array.
string
The job status with which to filter jobs in the specified queue. If you do not specify a status, only RUNNING jobs are returned.
integer
The maximum number of results returned by ListJobs in paginated output. When this parameter is used, ListJobs 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 ListJobs request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListJobs returns up to 100 results and a nextToken value if applicable.
string
The nextToken value returned from a previous paginated ListJobs 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.
