# Handle tags and labels
|
|
|
|
If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and want an
|
|
"automatic" tag management and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
|
|
for labels, you can do it in a dedicated step. The following workflow will use the [Docker meta action](https://github.com/crazy-max/ghaction-docker-meta)
|
|
to handle tags and labels based on GitHub actions events and Git metadata.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|

|
|
schedule:
|
|
- cron: '0 10 * * *' # everyday at 10am
|
|
push:
|
|
branches:
|
|
- '**'
|
|
tags:
|
|
- 'v*.*.*'
