This action gets tag name from commit that triggered the action and puts it into an environment variable GIT_TAG_NAME. It will also export is as an output named "tag".
You can also use optional parameters tagRegex and tagRegexGroup to extract a part from tag string.
Dead simple:
steps:
- uses: olegtarasov/[email protected]
id: tagName
with:
tagRegex: "foobar-(.*)" # Optional. Returns specified group text as tag name. Full tag string is returned if regex is not defined.
tagRegexGroup: 1 # Optional. Default is 1.
- name: Some other step # Output usage example
with:
tagname: ${{ steps.tagName.outputs.tag }}
- name: Yet another step # Environment variabl usage example
run: |
docker build . --file Dockerfile --tag docker.pkg.github.com/someimage:$GIT_TAG_NAME
You can also use named regex groups (thanks to PR from @jelgblad):
steps:
- uses: olegtarasov/[email protected]
id: tagName
with:
tagRegex: "(?<package>.*)-(?<version>.*)"
- name: Some other step # Output usage example
with:
dirname: ${{ steps.tagName.outputs.package }}
tagname: ${{ steps.tagName.outputs.version }}
