====== Docker - Security - Use a linter ======

Enforce **Dockerfile** best practices automatically by using a static code analysis tool such as [[https://github.com/hadolint/hadolint|hadolint linter]], that will detect and alert for issues found in a Dockerfile.

hadolint parses a **Dockerfile** and shows a warning for any errors that do not match its best practice rules.
