kustomize-bump

This script allows you to bump the tag versions of all the Docker images defined in a kustomization.yaml file.

It does this by:

1. Parsing kustomization.yaml
2. Finding out the tags and images of each field in images:
3. Asking docker-hub-rss which tags were released when
4. Skip image tags without any digits (probably means unversioned) (See KBUMP_NODIGITS for configuration)
5. Skip image tags with ['unstable', 'latest', 'testing', 'arm64', 'arm32'] in the name (See KBUMP_FORBIDDEN_WORDS for configuration)
6. Trying to magically find a good one (compare tag slugs, give less importance to older tags)
7. Writing the new candidate to kustomization.yaml

Usage

docker run -t -v $(pwd)/kustomization.yaml:/kustomization.yaml chauffer/kustomize-bump

Configuration

Environment variables:

• KBUMP_NODIGITS: Set to 0 to not skip images without numbers.
• KBUMP_FORBIDDEN_WORDS: Set to a comma separated string of forbidden words.
• KBUMP_FILEPATH: Path to kustomization.yaml. Defaults to /kustomization.yaml.
