Ephemeral Containers demo

Ephemeral Containers are available (as beta) from Kubernetes 1.23:

Pods are the fundamental building block of Kubernetes applications. Since Pods are intended to be disposable and replaceable, you cannot add a container to a Pod once it has been created. Instead, you usually delete and replace Pods in a controlled fashion using deployments.

Example: capturing Pod network traffic
