Hadolint is a smart Dockerfile linter written in Haskell that parses Dockerfiles into an AST and applies best-practice rules. It also lints the Bash code inside RUN instructions by leveraging ShellCheck.
Use cases
- lint dockerfiles for best practices
- validate bash in dockerfile run instructions
- check dockerfiles in ci pipeline
- catch bad practices in container builds
- enforce dockerfile style rules
When to choose
- you want automated best-practice checks for Dockerfiles
- you need ShellCheck-powered linting of RUN command shell code
- you want a fast standalone CLI or container-based linter for CI
When to avoid
- you need linting for docker-compose or Kubernetes manifests rather than Dockerfiles
- you need a general-purpose shell linter outside Dockerfiles
- you require IDE-only integration without CLI usage
