Do I need an existing pre-commit configuration file?

No, the skill is designed to detect an existing .pre-commit-config.yaml or create a new minimal configuration if one is not found.

What tool does this skill use for Dockerfile linting?

This skill uses Hadolint, the industry-standard linter for validating Dockerfile syntax and best practices.

Does it validate shell commands inside the Dockerfile?

Yes, Hadolint includes ShellCheck integration, allowing this skill to help you find issues in your RUN instructions.

Can I customize which linting rules are ignored?

Yes, the skill provides options to ignore common rules and can generate a .hadolint.yaml file for persistent project-wide customization.

Deployment & DevOps

Automates the integration of Hadolint into your pre-commit workflow to enforce Dockerfile best practices and security standards.

This skill streamlines the setup of Dockerfile linting by automatically detecting Dockerfiles within a project and configuring Hadolint as a pre-commit hook. It handles the creation or modification of your .pre-commit-config.yaml, sets up intelligent defaults for common rule ignores, and can generate a project-level .hadolint.yaml configuration to ensure consistent security, efficiency, and maintainability across the development lifecycle without manual configuration overhead.
