# action-docker-build-push

> Setup docker, build image and push

## Usage

Just set registry info, it will build and push.

```yml
      - name: Docker build push
        uses: seepine/action-docker-build-push@v1
        with:
          registry: ghcr.io
          username: ${{ github.actor }}
          password: ${{ secrets.DOCKER_PASSWORD }}
          platforms: linux/amd64,linux/arm64
```

The tags auto generate from `refs`.Eg the repo is `github.com/seepine/demo`, with registry is `ghcr.io` and with username is `seepine`.

- trigger push branch eg `main`
  - `ghcr.io/seepine/demo:main`
  - `ghcr.io/seepine/demo:latest`
- trigger push tag eg `v1.2.3`
  - `ghcr.io/seepine/demo:1.2.3`
  - `ghcr.io/seepine/demo:latest`
