Why do this rather than use a Dockerfile?

It seems like the tutorial is not really thinking the end-result and reproducibility of the container (the main use-case).

It is manual workflow to create a service inside container, when you instead should automate the process with Dockerfile/Containerfile or just shellsricpt it with Buildah.

What is the point of creating non-root user here when he adds it to the wheel group anyway?

Something you are not doing, when making a proper container image.

I liked the tutorial, it showed how to get started with some interesting choice of technologies.

What I would have liked to see more:

- Why not Docker? Why Podman instead of other container tools?

- Why Elixir instead of other languages? https://elixirschool.com/en/why

- Why not Phoenix?

- How to clean up after the tutorial: shut down Podman, etc.

I expanded the guide a bit more with some helpful resources to learning more about why Podman over Docker.

Why not Phoenix?

I wanted to keep the demonstration simple. Also it's helpful learning how a web framework works underneath instead of just using it blindly.

Why Elixir

Mainly for the fault tolerance and distributed networking.
