K8s is a very complex beast. But it give you a very good set of security defaults, and it is also a very well done implementation of a microservice application.

In this second article, I suggest to explore further two simple helm chart for getting a bit more inside K8s.

When you run pihole in a docker container, it could be difficult to build images on the same docker daemon, because docker-compose cannot pass DNS request to another container during build, and normal dns resolution fixes won’t work.

I am always amused on how complex K8s/Docker Swarm are, and how easy “plain” docker is.
