Kubernetes CKA Practice Question #13 - Creating a Multi-Container Pod with a Shared Volume

In this video, I walk you through Certified Kubernetes Administrator (CKA) Practice Question #13, where we set up a multi-container-pod in the default Namespace with three containers: c1, c2, and c3. The containers share a non-persistent volume that is mounted in all three containers. Here's the breakdown of what each container does:
Container c1: Runs an nginx:1.17.6-alpine image and sets the environment variable MY_NODE_NAME to the node name where the Pod is running.
Container c2: Runs a busybox:1.31.1 image and writes the output of the date command every second to the shared volume (date.log).
Container c3: Runs a busybox:1.31.1 image and continuously streams the contents of the date.log file to stdout using tail -f.
This video is ideal for those preparing for the CKA exam or anyone looking to deepen their understanding of multi-container Pods, shared volumes, and environment variables in Kubernetes.
Key topics covered:
Creating a multi-container Pod in Kubernetes
