containernetworking-plugins will install the Container Network Interface plugins which are required by kubernetes networking solutions to operate. Now the bundled containerd config doesn't quite work well with what kubernetes requires so we'll make changes to it:

I’m not sure if there is a book on this topic specifically, but the book and RFC I referenced in my earlier post will help you better understand the fundamentals behind these protocols. You can see an example CNI plug-in here to learn about how CNIs are structured.

Also make sure that you have cri-o, crictl, containernetworking-plugins, and buildah or docker installed.

In my home lab, I don’t use (nor need) any of the fancy CNI plugins like calico, cilium or weavenet. I’m really happy with bridge, host-local and portmap from containernetworking/plugins with some static routes between the nodes. The only problem is that I can’t use NetworkPolicies.
