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.

Best Freeish diagraming software for Docker Swarms and their networks.
You can always try weave scope, it'll map out your swarm for you. I've not used it for some time, but it was cool when I did.

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

Top 10 common Dockerfile linting issues
With Depot, we make use of two Dockerfile linters, hadolint and a set of Dockerfile linter rules that Semgrep has written to make a bit of a smarter Dockerfile linter.

Is adding a USER best practice?
The most common linter I've seen and used it Hadolint, which does: https://github.com/hadolint/hadolint/wiki/DL3002 I didn't bother checking to see if alternatives also support this as well though.

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.
