### Tags handling
### Tags and labels handling
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, you will have to do it in a dedicated step [for now](https://github.com/docker/build-push-action/issues/116).
"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 workflow below with the `Prepare` step will generate a
[`tags` output](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjobs_idoutputs):
* On `pull_request` event with `refs/pull/2/merge` ref and `a123b57` sha:
* `user/app:pr-2`
* On `push` event with `refs/heads/master` ref and `676cae2` sha:
* On `push` event with `refs/heads/<default_branch>` ref and `676cae2` sha:
* `user/app:sha-676cae2`
* `user/app:edge`
* On `push` event with `refs/heads/dev` ref and `cf20257` sha:
