Hadolint Dockerfile Linter

Hadolint — Linter for your Dockerfile

[Source: Hadolint on GitHub]

One such linter is hadolint. It parses a Dockerfile and shows a warning for any errors that do not match its best practice rules.

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.

That sounds very interesting. Maybe it would not be very hard to implement a prototype of such a system with Stan?

Would you be okay if we add Soisy to the list of companies using stan?

However, I'm a huge fan of static tools like this in general. I've heard great things about https://package.elm-lang.org/packages/jfmengels/elm-review/latest/ and I need to try out https://github.com/kowainik/stan. Also its possible HLint has ways to write more advanced rules and I just don't know about them, but even if that's so hopefully I've explained why just dropping it in isn't a huge win.
