If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and you 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 [for now](https://github.com/docker/build-push-action/issues/116).

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
