pre-commit-kustomize-check

pre-commit-kustomize-check utilizes a docker container to run kustomize build against directories in your repository. This repository is based on pre-commit-docker-kustomize, with a few crucial improvements:

• kustomize-check defaults to using a pre-built image, which drastically speeds up checks, as the image can be cached locally. If you prefer to build the image locally for security, you can utilize the kustomize_check_local hook instead, which utilizes the original behavior of building the docker image locally for each run.
• kustomize-check utilizes renovate to automatically keep up with upstream versions of the kustomize binary. kustomize version availability starts with v4.5.6
• the kustomize_check docker image stored in dockerhub is now multiarch, allowing it to be run natively on the following platforms: linux/amd64, linux/arm64, linux/ppc64le, linux/s390x

Configuration

pre-commit-kustomize-check utilizes standard pre-commit hook configuration.

Global Config Options

• rev: the version of kustomize you wish to use in this hook (this repository is tagged by kustomize version).
• repo: this repo (https://github.com/rtrox/pre-commit-kustomize-check)

Hook configuration

• id: kustomize_check, kustomize_check_local, or kustomize_check_system.
  • kustomize_check uses the dockerhub image built by this repo
  • kustomize_check_local builds the docker image locally for each run.
  • kustomize_check_system does not use docker, and instead uses the kustomize binary already installed on your system
• name: A unique name which will be printed with pre-commit output.
• args: The directory you wish to build with kustomize
