Docker is dead?!? Podman - an alternative tool?
12 projects | dev.to | 8 Jul 2022

Another possibility to switch from Docker containers are the so-called Unikernels. These are briefly mentioned here for the sake of completeness, even though they currently have no significance in the Kubernetes context. An interesting blog post on the topic can be found on Hackernoon. It is an interesting construct that may one day find its way into the world of Kubernetes if containers can be replaced by unikernels. Currently, the use of unikernels would not be feasible in my opinion.

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 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.

It's an open source project. https://github.com/containers/podman and https://podman.io - go there, get engaged, see what's going on and most important become part of the community and contribute!
