How to view logs of failed jobs with kubectl?

Question

I've created a Kubernetes job that has now failed. Where can I find the logs to this job?

I'm not sure how to find the associated pod (I assume once the job fails it deletes the pod)?

Running kubectl describe job does not seem to show any relevant information:

One other approach:

• kubectl describe job $JOB
• Pod name is shown under "Events"
• kubectl logs $POD
