Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Writing a Minecraft server from scratch in Bash (2022)
To skip the "move your scripts to standalone files" step some devs don't like, consider something like https://github.com/hadolint/hadolint which runs Shellcheck over inline scripts within Containerfiles.

I reduced the size of my Docker image by 40% – Dockerizing shell scripts
This is neat :)
I love going and making containers smaller and faster to build.
I don't know if it's useful for alpine, but adding a --mount=type=cache argument to the RUN command that `apk add`s might shave a few seconds off rebuilds. Probably not worth it, in your case, unless you're invalidating the cached layer often (adding or removing deps, intentionally building without layer caching to ensure you have the latest packages).
Hadolint is another tool worth checking out if you like spending time messing with Dockerfiles: https://github.com/hadolint/hadolint

Checkmake: Experimental Linter/Analyzer for Makefiles
Some discussion on that here:
https://github.com/koalaman/shellcheck/issues/58
The hadolint project does shell checking for Dockerfiles and it uses shellcheck:
https://github.com/hadolint/hadolint
So the approach is definitely feasible, but you do need a new project and probably it needs to be written in Haskell.

Dokter: the doctor for your Dockerfiles
how does this compare to something like hadolint?
Also, have you run across Hadolint for linting? https://github.com/hadolint/hadolint
-
Are there tools that tell you if you can optimize your dockerfiles?
Wow that's a great tool and it has a ton of integrations https://github.com/hadolint/hadolint/blob/master/docs/INTEGRATION.md
- Dhall: A Gateway Drug to Haskell
- can you recommend active Haskell open source projects?

Just Say No To `:Latest`
Worth noting that Hadolint[1] raises warnings the issues mentioned in the article. Some examples of warnings:
- https://github.com/hadolint/hadolint/wiki/DL3007: Using latest is prone to errors if the image will ever update. Pin the version explicitly to a release tag.

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.

Exploring Podman: A More Secure Docker Alternative
AFAIK podman either already supports pods in quadlet container files, or will in the near future. https://github.com/containers/podman/pull/20762

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!

Jekyll Docker
If you are using a rootless container management system, you can set the JEKYLL_ROOTLESS environment variable to any non-zero value. For example, you can use the following to initialize a new jekyll project in the current directory using podman.
