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

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.

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

[RFC] Generate Cabal files from TOML
There are ways to get around this, but it's not easy and doesnt scale: https://github.com/sol/hpack/issues/194

cabal-version for a stack managed project
-- see: https://github.com/sol/hpack ```

Haskell as a first timer - Am I missing something ?
The yaml you are talking about is part of a tool called hpack. This tool can be used on it's own (and with cabal-install as such), it just so happens that stack has it's own internal copy of it and runs it automatically whenever it finds a package.yaml.
-
Using External Pacakges With Cabal
I know this sounds more complicated at first glance, but I personally would suggest using hpack to generate cabal files from a package.yaml instead of directly editing your-project.cabal.
What are some alternatives?
trivy - Find vulnerabilities, misconfigurations, secrets, SBOM in containers, Kubernetes, code repositories, clouds and more
castle - A tool to manage shared cabal-install sandboxes.
dockle - Container Image Linter for Security, Helping build the Best-Practice Docker Image, Easy to start
AlgorithmW - Example implementation of Algorithm W for Hindley-Milner type inference
docker-bench-security - The Docker Bench for Security is a script that checks for dozens of common best-practices around deploying Docker containers in production.
bumper - Haskell tool to automatically bump package versions transitively.
stan - 🕵️ Haskell STatic ANalyser
hdocs - Haskell docs tool
hlint - Haskell source code suggestions
hfd - Flash debugger with haskeline interface
grype - A vulnerability scanner for container images and filesystems
