Pods: Lifecycle, Init Containers & Sidecars
A Pod is the smallest deployable unit in Kubernetes -- not a container. A Pod wraps one or more containers that share the same network namespace (same IP, same localhost) and can share storage volumes
Learning objectives
- Trace a Pod through its full phase lifecycle, and explain what each phase actually means.
- Explain what an init container guarantees that a regular container in the same Pod doesn't.
- Distinguish a sidecar container from an init container by when each one runs relative to the main application container.
