Add major and major.minor tags to docker images that have only major.minor.patch as tags available.
Features

- 🔍 Flexible filtering with regex, prefix, and suffix support
- ⚡ Digest-based optimization (skips copying when images are identical)
- 🧪 Comprehensive test suite
- 🚀 Automated CI/CD pipeline with GitHub Actions
Usage
Login
docker run --rm -it -v ~/.docker/config.json:/root/.docker/config.json oidatiftla/docker-tag-enhancer --login --registry registry.example.com
With filter
docker run --rm -it -v ~/.docker/config.json:/root/.docker/config.json oidatiftla/docker-tag-enhancer -s registry.example.com/name1 -d registry.example.com/name2 -f '^((?!-rc|^8\.|^9\.|^10\.|^11\.|^12\.).)*$'
With leading-zero version components (e.g. zero-padded timestamps)
By default, version components must not have leading zeros (0, 1, 2, ... 9, 10, ... but not 01). Use --allow-leading-zeros if your tags contain zero-padded numbers, e.g. 0.2609.0611.1310.
docker run --rm -it -v ~/.docker/config.json:/root/.docker/config.json oidatiftla/docker-tag-enhancer -s registry.example.com/name1 -d registry.example.com/name2 --allow-leading-zeros
GitHub Container Registry (GHCR) read existing tags
For some reason (source, source) the GITHUB_TOKEN needs to be encoded with base64:
...
permissions:
contents: read
packages: write
...
jobs:
job:
runs-on: ubuntu-latest
steps:
...
- name: Retrieve tags
run: |
ENCODED=$(echo -n "${{ secrets.GITHUB_TOKEN }}" | base64)
skopeo list-tags \
--registry-token="${ENCODED}" \
docker://${DOCKER_REGISTRY_IMAGE}
