### Global expressions
The following [Handlebars template](https://handlebarsjs.com/guide/) expressions for `prefix`, `suffix` and `value`
attributes are available:
| Expression | Output |
|--------------------------|----------------------|
| `{{branch}}` | `master` |
| `{{tag}}` | `v1.2.3` |
| `{{sha}}` | `90dd603` |
```yaml
tags: |
# dynamically set the branch name as a prefix
type=sha,prefix={{branch}}-
# dynamically set the branch name and sha as a custom tag
type=raw,value=mytag-{{branch}}-{{sha}}
```
### Overwrite labels
If some of the [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
