What you will be able to do

A pod wraps one or more containers.
Pods are disposable; use controllers for real workloads.
Use kubectl logs and describe first.
Set resource requests and limits.

In plain English

A pod is the smallest deployable unit and usually holds one container. Pods are ephemeral: do not rely on their names or local storage. Use kubectl logs, describe and exec to debug.
