    Like hadolint: Dockerfile linter, validate inline bash, written in Haskell; Purescript, Unison, Idris languages implemented in Haskell. I recommend to check ideas behinds those projects. Especially Unison's mind-blowing something naive idea about infinite computational resources.

    3. Hadolint: https://github.com/hadolint/hadolint Hadolint is a Dockerfile linter that helps you build best practice Docker images, reducing vulnerabilities in your container configurations.

    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.

    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

    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.

    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.

    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.
