matchhostfsowner VS podman

I wrote a portable solution for the user ID mapping problem: https://github.com/FooBarWidget/matchhostfsowner

I'm at the verge of releasing version 1.0 of MatchHostFsOwner, a solution for the Docker filesystem owner matching problem. MatchHostFsOwner is my first serious Rust project. It's an entrypoint program to be used in Docker containers. Rust's error handling idioms force me to take all possible error conditions seriously, while also encouraging me to have proper error messages for each error condition. I use rust-musl-builder to generate statically-linked Linux binaries that work on all Linux distros.

I'm working on a solution based on strategy 1 (matching the container's UID/GID with the host's). This solution already works, and I've already deployed it in a few of my own projects, but isn't very well-documented yet. I'm also working on more automated tests to guarantee that it's rock-solid. Would you be interested in testing it and giving feedback once it's in a more ready state?

A lot of well-known Docker alternatives emerged at this point, the most commonly recommended of which must be Podman (along with Podman Desktop). This is what I use on my Windows machines, and this was the first solution that I tried on the Macbook as well.

Podman

Even though we will focus on Docker for this article, I wanted to mention that there are more container creation and management tools such as Podman, Rkt, and so on.

By using containerization, the application will always have the same configuration that is used in the development environment and production environment. There is no more "It works on my machine". Some examples of containerization technologies are Docker and Podman.

Podman Documentation. Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.

AFAIK podman either already supports pods in quadlet container files, or will in the near future. https://github.com/containers/podman/pull/20762

Podman as a devcontainers engine doesn't currently work if you use devcontainer features [1] or (and this sounds like you're issue) if you use WSL2.

I haven't submitted the WSL2 issue to the Podman team yet. If you get to it before I do, can you like it here?

You can also use their Oracle Linux Docker images with the database preinstalled using either Podman or Docker. Just make absolutely sure you are downloading something you are licensed to use, because it seems really easy to accidentally infringe copyright via this method.
