Tutorial: Map a running pod back to its job

A pod has labels that indicate the jobId and uuid of the compute environment that it belongs to. AWS Batch injects environment variables so the job’s runtime can reference job information. For more information, see AWS Batch job environment variables. You can view this information by running the following command. The output is as follows.

$ kubectl describe pod aws-batch.14638eb9-d218-372d-ba5c-1c9ab9c7f2a1 -n my-aws-batch-namespace
