Haskell Dockerfile Linter
A smarter Dockerfile linter that helps you build best practice Docker images by parsing the Dockerfile AST and linting inline bash.
What is Haskell Dockerfile Linter?
Hadolint is a Dockerfile linter written in Haskell that analyzes Dockerfiles for errors and best practices. It parses the Dockerfile into an Abstract Syntax Tree (AST) and applies a comprehensive set of rules to ensure secure, efficient, and maintainable container images. It also integrates ShellCheck to lint the Bash code inside `RUN` instructions.
DevOps engineers, platform engineers, and developers who build Docker images and want to enforce best practices, improve security, and maintain consistency across their containerized applications.
Developers choose Hadolint for its deep AST-based analysis, integration with ShellCheck for bash linting, and extensive rule set that goes beyond simple syntax checking to enforce Docker best practices. Its flexibility with configuration and output formats makes it ideal for CI/CD pipelines.
