Podman: A tool for managing OCI containers and pods
This sounds exactly like Singularity http://singularity.hpcng.org/

What is a singularity container and how do I use it?
never used it but a very popular example of a container is docker (that link says what a container is) and singularity just looks like another container flavour (maybe specific to HPCs?)

Youki, a container runtime in Rust, passed all the default tests provided by opencontainers.
The re-exec pattern is not the only way you can solve this in Go. I actually rebuilt a container runtime from C to Go (for the HPC market) and we had to solve this problem. We did it by essentially forking before any Go code gets run. Here’s the code for the main binary that actually spawns the container process. It’s half C, half Go. https://github.com/hpcng/singularity/tree/master/cmd/starter

A Gentle Introduction to Containerization and Docker
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.

A Journey to Find an Ultimate Development Environment
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 Desktop 1.6 released: Even more Kubernetes and Containers features
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?

Oracle data base
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.

A call for Podman comparison charts
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!
