About

GitHub Action to extract metadata (tags, labels) for Docker. This action is particularly useful if used with Docker Build Push action.

Customizing

inputs

Following inputs can be used as step.with keys

Name Type Description
images List/CSV List of Docker images to use as base name for tags
tag-sha Bool Add git short SHA as Docker tag (default false)
tag-edge Bool Enable edge branch tagging (default false)
tag-edge-branch String Branch that will be tagged as edge (default repo.default_branch)
tag-semver List/CSV Handle Git tag as semver template if possible
tag-match String RegExp to match against a Git tag and use first match as Docker tag
tag-match-group Number Group to get if tag-match matches (default 0)
tag-latest Bool Set latest Docker tag if tag-semver, tag-match or Git tag event occurs (default true)
tag-schedule String Template to apply to schedule tag (default nightly)
tag-custom List/CSV List of custom tags
tag-custom-only Bool Only use tag-custom as Docker tags
sep-tags String Separator to use for tags output (default \n)
sep-labels String Separator to use for labels output (default \n)

List/CSV type can be a newline or comma delimited string

tag-semver and tag-match are mutually exclusive

outputs

Following outputs are available

Name Type Description
version String Generated Docker image version
tags String Generated Docker tags
labels String Generated Docker labels

Notes

Latest tag

Latest Docker tag will be generated by default on push tag event. If for example you push the v1.2.3 Git tag, you will have at the output of this action the Docker tags v1.2.3 and latest. But you can allow the latest tag to be generated only if tag-semver is a valid semver or if Git tag matches a regular expression with the tag-match input. Can be disabled if tag-latest is false.

Handle semver tag

If Git tag is a valid semver you can handle it to output multi Docker tags at once. tag-semver supports multi-line Handlebars template with the following inputs:

Git tag tag-semver Valid Output tags Output version
v1.2.3 {{raw}} v1.2.3, latest v1.2.3
v1.2.3 {{version}} 1.2.3, latest 1.2.3
v1.2.3 {{major}}.{{minor}} 1.2, latest 1.2
v1.2.3 v{{major}} v1, latest v1
v1.2.3 {{minor}} 2, latest 2
v1.2.3 {{patch}} 3, latest 3
v1.2.3 {{major}}.{{minor}}
{{major}}.{{minor}}.{{patch}}
1.2, 1.2.3, latest 1.2*
v2.0.8-beta.67 {{raw}} 2.0.8-beta.67** 2.0.8-beta.67
v2.0.8-beta.67 {{version}} 2.0.8-beta.67 2.0.8-beta.67
v2.0.8-beta.67 {{major}}.{{minor}} 2.0.8-beta.67** 2.0.8-beta.67
release1 {{raw}} release1 release1

*First occurrence of tag-semver will be taken as output.version

**Pre-release (rc, beta, alpha) will only extend {{version}} as tag because they are updated frequently, and contain many breaking changes that are (by the author's design) not yet fit for public consumption.

tag-match examples

Git tag tag-match tag-match-group Match Output tags Output version
v1.2.3 \d{1,3}.\d{1,3}.\d{1,3} 0 1.2.3, latest 1.2.3
v2.0.8-beta.67 v(.*) 1 2.0.8-beta.67, latest 2.0.8-beta.67
v2.0.8-beta.67 v(\d.\d) 1 2.0, latest 2.0
release1 \d{1,3}.\d{1,3} 0 release1 release1
20200110-RC2 \d+ 0 20200110, latest 20200110

Schedule tag

tag-schedule is specially crafted input to support Handlebars template with the following expressions:

Expression Example Description
{{date 'format'}} {{date 'YYYYMMDD'}} > 20200110 Render date by its moment format

You can find more examples in the CI workflow.

Overwrite labels

If some of the OCI Image Format Specification labels generated are not suitable, you can overwrite them like this:

      -
        name: Build and push
        uses: docker/build-push-action@v2
        with:
          context: .
          file: ./Dockerfile
          platforms: linux/amd64,linux/arm64,linux/386
          push: ${{ github.event_name != 'pull_request' }}
          tags: ${{ steps.docker_meta.outputs.tags }}
          labels: |
            ${{ steps.docker_meta.outputs.labels }}
            org.opencontainers.image.title=MyCustomTitle
            org.opencontainers.image.description=Another description
            org.opencontainers.image.vendor=MyCompany            

Keep up-to-date with GitHub Dependabot
