| # The release event is a superset of the push tag event, | |
| # so we expect two tags to be generated by docker/metadata-action | |
| # based on the behaviour for the type=semver,pattern=... tag type: | |
| # 1. a semver tag vX.Y.Z (from the release Git tag; this is what will be used as the image version in the generated label) | |
| # 2. latest (as type=semver,pattern=... is part of the latest tag handling) | |
