Multi-container support

[ecomaikgolf]

We could leverage the following tree structure:

challenge1/Dockerfile
challenge2/Dockerfile
challenge3/Dockerfile

And build under NAME-{1,2,3} to have multiple container support, wrapped with a pod.

The pods can be deployed via Kubernetes pods. I think docker-compose support should be straightforward, podman quadlets I'm not so sure.

Forwarding between pod network could be unrestricted, and the PORT for forwarding could be from inside-outside pod.
