pre-commit-hooks

This repository contains Jiri Tyr's pre-commit hooks.

Hooks

docker-image

This hook is an extension of the original pre-commit implementation of running checks in a Docker image. It's using the actual pre-commit code but it extends it with functionality for a better detection of the "Docker in Docker" scenario (e.g. when running in a custom Docker image in GitHub Workflows). The detection comprise of these checks:

• Using Control Groups
• Existence of .dockerenv
• Using CPU Scheduling Info

Usage

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: docker-image
        name: Run /tools/validate.sh in container
        args:
          - my_user/my_image:latest
          - -c
          - /tools/validate.sh
        pass_filenames: false

check-helm-version

This hook checks if the Helm chart version was incremented or not. This helps to prevent the Helm chart push to fail if there already exists a Helm chart with the same version in the registry. If the registry allows to overwrite an existing Helm chart version, this hook helps to prevent the overwrite.

Usage

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: check-helm-version

By default, the hook compares the version in the current branch to the version in the main branch. The branch name can be changed by adding the --branch argument:

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: check-helm-version
        args:
          - --branch=default

If the branch cannot be found locally, the hook will try to create the branch head from the remote. The remote name can be set via --remote argument:

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: check-helm-version
        args:
          - --remote=upstream
          - --branch=default

It's also possible to autofix the version incrementation by specifying the --autofix argument:

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: check-helm-version
        args:
          - --autofix

By default, the patch portion of the version is incremented. Different portion (major, minor, prerelease and build) can be specified with the --autofix-portion argument:

repos:
  - repo: https://github.com/jtyr/pre-commit-hooks
    rev: v1.3.3
    hooks:
      - id: check-helm-version
        args:
          - --autofix
          - --autofix-portion=minor
