## About
|
|
|
|
GitHub Action to extract metadata (tags, labels) for Docker. This action is particularly useful if used with
|
|
[Docker Build Push](https://github.com/docker/build-push-action) action.
|
|

## Notes
|
|
|
|
### Latest tag
|
|
|
|
`latest` tag is created with the following conditions:
|
|
|
|
* Git tag is a valid [semver](https://semver.org/)
|
|
* Provided `tag-coerce-tag` is valid
|
|
|
|
If `tag-latest-match` is filled, then it has priority over the creation of the tag.
|
|
|
|
### Coerces Git tag
|
|
|
|
Provides a very forgiving translation of a non-semver tag to semver. For more information see
|
|
[Coercion section](https://www.npmjs.com/package/semver#coercion). `tag-coerce-tag` supports
|
|
[Handlebars template](https://handlebarsjs.com/guide/) with the following inputs:
|
|
|
|
| `tag-coerce-tag` | Git tag | Version |
|
|
|-------------------------|----------|---------|
|
|
| `{{raw}}` | `v1.2.3` | `1.2.3` |
|
|
| `{{major}}.{{minor}}` | `v1.2.3` | `1.2` |
|
|
| `{{major}}` | `v1.2.3` | `1` |
|
|
| `{{minor}}` | `v1.2.3` | `2` |
|
|
| `{{patch}}` | `v1.2.3` | `3` |
|
|
|
|
### Schedule tag
|
|
|
|
`tag-schedule` is specially crafted input to support [Handlebars template](https://handlebarsjs.com/guide/) with
|
|
the following expressions:
|
|
|
|
| Expression | Example | Description |
|
|
|-------------------------|-------------------------------------------|------------------------------------------|
|
|
| `{{date 'format'}}` | `{{date 'YYYYMMDD'}}` > `20200110` | Render date by its [moment format](https://momentjs.com/docs/#/displaying/format/)
|
|
|
|
You can find more examples in the [CI workflow](.github/workflows/ci.yml).
|
|
|
|
## Keep up-to-date with GitHub Dependabot
|
|
|
|
Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
|
|
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
|
|
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
|
|
|
|
```yaml
|
|
version: 2
|
|
updates:
|
|
# Maintain dependencies for GitHub Actions
|
|
- package-ecosystem: "github-actions"
|
|
directory: "/"
|
|
schedule:
|
|
interval: "daily"
|
|
```
|
|
|
|
