Cranoaklabs Repos and Demos.

The cranoaklab repos, themes and demos section is exactly that:

Themes: Themes are larger efforts that consist of muliple repos due to its complexity and depth.
Example Kubernetes The Hard Way - AWS Version. Kubernetes The Hardway is a theme consisting of multiple repose pulled together typically with multiple Demos.
Repos Repos vary in size and purpose. Repos always align with a Demo and often align with other repos to make up a thems. Example: State conflicts between argocd-git and k8 cluster scaling
Demos Demos may pull multiple repos together or have its own repo coupled with a demo theme. An example would be Argocd stare conflics with Kubernetes scaling.

Themes

cilium cni
In the real world i used calico to solve this problem. Both with IPv4 and using IPv6

Could rewrite as migrate app from openshift on prem to k8 on aws.
