If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and want an
|
||||
"automatic" tag management through Git reference and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)

for labels, you will have to do it in a dedicated step.

The following workflow with the `Prepare` step will generate some [outputs](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjobs_idoutputs)
|
||||
to handle tags and labels based on GitHub actions events.

This is just an example to show many cases that you might want to use and that you will have to adapt according

to your needs:
