### Complete workflow
* On `pull_request` event, Docker image `name/app:edge` is **built**.
* On `push` event, Docker image `name/app:edge` is **built** and **pushed** to DockerHub.
* On `schedule` event, Docker image `name/app:nightly` is **built** and **pushed** to DockerHub.
* On `push tags` event, Docker image `name/app:<version>` and `name/app:latest` is **built** and **pushed** to DockerHub.
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
might want to use:
| Event | Ref | Commit SHA | Docker Tag | Pushed |
|-----------------|-------------------------------|------------|------------------------------------|--------|
| `schedule` | | | `nightly` | Yes |
| `pull_request` | `refs/pull/2/merge` | `a123b57` | `pr-2` | No |
| `push` | `refs/heads/<default_branch>` | `676cae2` | `sha-676cae2`, `edge` | Yes |
| `push` | `/refs/heads/dev` | `cf20257` | `sha-676cae2`, `dev` | Yes |
| `push` | `/refs/heads/my/branch` | `a5df687` | `sha-a5df687`, `my-branch` | Yes |
| `push tag` | `/refs/tags/v1.2.3` | | `v1.2.3`, `v1.2`, `v1`, `latest` | Yes |
