hadolint
A smarter Dockerfile linter that helps you build best practice Docker images by parsing the AST and linting inline Bash.
What is hadolint?
Hadolint is a Dockerfile linter that analyzes Dockerfiles for syntax errors and best practice violations. It helps developers build secure, efficient, and maintainable Docker images by applying rules based on Docker's official best practices and linting inline Bash code using ShellCheck.
DevOps engineers, platform engineers, and developers who build and maintain Docker images and want to enforce security and efficiency standards in their container pipelines.
Hadolint provides deeper analysis than basic linters by parsing the Dockerfile AST and integrating ShellCheck, offering comprehensive rule coverage, flexible configuration, and seamless CI/CD integration to catch issues early.
