As far as downtimes go, most suck. Then there are some that are more like happy little opportunities to learn something new. When Gitlab in my homelab started returning 500s, I had no idea how blessed I was. I was at best annoyed.

This is an extension of very helpful article Running Docker on WSL2 without Docker Desktop (the right way) by Felipe Santos. My post attempts to go further and solve a very specific issue within WSL - the absence of nftables support. This is something you might not encounter unless you start running docker in docker or attempt to run docker images that rely on nftables support in some way.

I tend to use Molecule quite heavily and I often end up using docker to emulate actual full blown linux systems or kubernetes cluster in a container, which is where the absence of some kernel features shows up.

This could've been called "Learning Kubernetes the hard way", because that's basically what I was trying to achieve here. It wasn't so much about learning how to use Kubernetes via its ingenious API as it was about learning about its individual components. If you want to just run Kubernetes locally, there's Minikube, that will give you nice VM with everything already set up.

What I've wanted to achieve is to have a set of components, all nicely isolated with a well defined connection between each other so I can add them, remove them and break the connections and see how this affects the cluster. To put it simply I was interested in Ops side of running Kubernetes. This is why I took Hyperkube and mixed it with docker-compose and tried to stand up Kubernetes "from scratch".

Let's get started..

Earlier on I've shown you how I run docker containers on NAS using systemd. This time, I'll show you an easy way to configure systemd with Ansible that will get you running containers in no time. (and in reproducible and automated way)

Has science gone too far? It might look so, because:

1. It feels like a huge over-engineering to implement CI at home.
2. What would you integrate anyway?
3. Just why?

Well let me explain my reasons.
