### Major version zero
|
||||||
|
|
||||||
|
Major version zero (`0.y.z`) is for initial development and **may** change at any time. This means the public API
|
||||||
|
[**should not** be considered stable](https://semver.org/#spec-item-4).
|
||||||
|
|
||||||
|
In this case, Docker tag `0` **should not** be generated if you're using [`type=semver`](#typesemver) with `{{major}}`
|
||||||
|
pattern. You can manage this behavior like this:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# refs/tags/v0.1.2
|
||||||
|
tags: |
|
||||||
|
# output 0.1.2
|
||||||
|
type=semver,pattern={{version}}
|
||||||
|
# output 0.1
|
||||||
|
type=semver,pattern={{major}}.{{minor}}
|
||||||
|
# disabled if major zero
|
||||||
|
type=semver,pattern={{major}},enable=${{ !startsWith(github.ref, 'refs/tags/v0.') }}
|
||||||
|
```
