## `flavor` input
|
||||||
|
|
||||||
|
`flavor` defines a global behavior for [`tags`](#tags-input):
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
flavor: |
|
||||||
|
latest=auto
|
||||||
|
prefix=
|
||||||
|
suffix=
|
||||||
|
```
|
||||||
|
|
||||||
|
* `latest=<auto|true|false>`: Handle [latest tag](#latest-tag) (default `auto`)
|
||||||
|
* `prefix=<string>`: A global prefix for each generated tag
|
||||||
|
* `suffix=<string>`: A global suffix for each generated tag
|
||||||
|
|
||||||
|
## `tags` input
|
||||||
|
|
||||||
|
`tags` is the core input of this action as everything related to it will reflect the output metadata. This one is in
|
||||||
|
the form of a key-value pair list in CSV format to remove limitations intrinsically linked to GitHub Actions
|
||||||
|
(only string format is handled in the input fields). Here is an example:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=schedule
|
||||||
|
type=ref,event=branch
|
||||||
|
type=ref,event=tag
|
||||||
|
type=ref,event=pr
|
||||||
|
type=semver,pattern={{version}}
|
||||||
|
type=semver,pattern={{major}}.{{minor}}
|
||||||
|
type=semver,pattern={{major}}
|
||||||
|
type=sha
|
||||||
|
```
|
||||||
|
|
||||||
|
Each entry is defined by a `type`, which are:
|
||||||
|
|
||||||
|
* [`type=schedule`](#typeschedule)
|
||||||
|
* [`type=semver`](#typesemver)
|
||||||
|
* [`type=match`](#typematch)
|
||||||
|
* [`type=edge`](#typeedge)
|
||||||
|
* [`type=ref`](#typeref)
|
||||||
|
* [`type=raw`](#typeraw)
|
||||||
|
* [`type=sha`](#typesha)
|
||||||
|
|
||||||
|
And global attributes:
|
||||||
|
|
||||||
|
* `enable=<true|false>` enable this entry (default `true`)
|
||||||
|
* `priority=<number>` priority to manage the order of tags
|
||||||
|
* `prefix=<string>` add prefix
|
||||||
|
* `suffix=<string>` add suffix
|
||||||
|
|
||||||
|
Default entries if `tags` input is empty:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=schedule
|
||||||
|
type=ref,event=branch
|
||||||
|
type=ref,event=tag
|
||||||
|
type=ref,event=pr
|
||||||
|
```
|
||||||
|
|
||||||

`pattern` is a specially crafted attribute to support [Handlebars template](https://handlebarsjs.com/guide/) with
|
||||||
|
the following expressions:
|
||||||
|
* `date 'format'` ; render date by its [moment format](https://momentjs.com/docs/#/displaying/format/)
|
||||||
|
|
||||||
|
| Pattern | Output |
|
||||||
|
|--------------------------|----------------------|
|
||||||
|
| `nightly` | `nightly` |
|
||||||
|
| `{{date 'YYYYMMDD'}}` | `20210326` |
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=schedule,enable=true,priority=1000,prefix=,suffix=,pattern=nightly
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=semver`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# minimal
|
||||||
|
type=semver,pattern={{version}}
|
||||||
|
```
|
||||||
|
|
||||||
|
Will be used on a [push tag event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#push)
|
||||||
|
and requires a valid Git tag [semver](https://semver.org/).
|
||||||
|
|
||||||
|
`pattern` attribute supports [Handlebars template](https://handlebarsjs.com/guide/) with the following expressions:
|
||||||
|
* `raw` ; the actual semver
|
||||||
|
* `version` ; shorthand for `{{major}}.{{minor}}.{{patch}}` (can include pre-release)
|
||||||
|
* `major` ; major version identifier
|
||||||
|
* `minor` ; minor version identifier
|
||||||
|
* `patch` ; patch version identifier
|
||||||
|
|
||||||
|
| Git tag | Pattern | Output |
|
||||||
|
|--------------------|----------------------------------------------------------|----------------------|
|
||||||
|
| `v1.2.3` | `{{raw}}` | `v1.2.3` |
|
||||||
|
| `v1.2.3` | `{{version}}` | `1.2.3` |
|
||||||
|
| `v1.2.3` | `{{major}}.{{minor}}` | `1.2` |
|
||||||
|
| `v1.2.3` | `v{{major}}` | `v1` |
|
||||||
|
| `v1.2.3` | `{{minor}}` | `2` |
|
||||||
|
| `v1.2.3` | `{{patch}}` | `3` |
|
||||||
|
| `v2.0.8-beta.67` | `{{raw}}` | `2.0.8-beta.67`* |
|
||||||
|
| `v2.0.8-beta.67` | `{{version}}` | `2.0.8-beta.67` |
|
||||||
|
| `v2.0.8-beta.67` | `{{major}}.{{minor}}` | `2.0.8-beta.67`* |
|
||||||
|
|
||||||
|
> *Pre-release (rc, beta, alpha) will only extend `{{version}}` as tag because they are updated frequently,
|
||||||
|
> and contain many breaking changes that are (by the author's design) not yet fit for public consumption.
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=semver,enable=true,priority=900,prefix=,suffix=,pattern=
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=match`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# minimal
|
||||||
|
type=match,pattern=\d{8}
|
||||||
|
# double quotes if comma in pattern
|
||||||
|
type=match,"pattern=\d{1,3}.\d{1,3}.\d{1,3}"
|
||||||
|
# define match group
|
||||||
|
type=match,pattern=v(.*),group=1
|
||||||
|
```
|
||||||
|
|
||||||
|
Can create a regular expression for matching Git tag with a pattern and capturing group. Will be used on a
|
||||||
|
[push tag event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#push).
|
||||||
|
|
||||||
|
| Git tag | Pattern | Group | Output |
|
||||||
|
|-------------------------|-------------------------------|---------|------------------------|
|
||||||
|
| `v1.2.3` | `\d{1,3}.\d{1,3}.\d{1,3}` | `0` | `1.2.3` |
|
||||||
|
| `v2.0.8-beta.67` | `v(.*)` | `1` | `2.0.8-beta.67` |
|
||||||
|
| `v2.0.8-beta.67` | `v(\d.\d)` | `1` | `2.0` |
|
||||||
|
| `20200110-RC2` | `\d+` | `0` | `20200110` |
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=group,enable=true,priority=800,prefix=,suffix=,pattern=,group=0
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=edge`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# minimal
|
||||||
|
type=edge
|
||||||
|
# define default branch
|
||||||
|
type=edge,branch=main
|
||||||
|
```
|
||||||
|
|
||||||
|
An `edge` tag reflects the last commit of the active branch on your Git repository. I usually prefer to use `edge`
|
||||||
|
as a Docker tag for a better distinction or common pattern. This is also used by official images
|
||||||
|
like [Alpine](https://hub.docker.com/_/alpine).
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=edge,enable=true,priority=700,prefix=,suffix=,branch=$repo.default_branch
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=ref`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# minimal branch event
|
||||||
|
type=ref,event=branch
|
||||||
|
# minimal tag event
|
||||||
|
type=ref,event=tag
|
||||||
|
# minimal pull request event
|
||||||
|
type=ref,event=pr
|
||||||
|
```
|
||||||
|
|
||||||
|
This type handles Git ref (or reference) for the following events:
|
||||||
|
* `branch` ; eg. `refs/heads/master`
|
||||||
|
* `tag` ; eg. `refs/tags/v1.0.0`
|
||||||
|
* `pr` ; eg. `refs/pull/318/merge`
|
||||||
|
|
||||||
|
| Event | Ref | Output |
|
||||||
|
|-----------------|-------------------------------|-------------------------------|
|
||||||
|
| `pull_request` | `refs/pull/2/merge` | `pr-2` |
|
||||||
|
| `push` | `refs/heads/master` | `master` |
|
||||||
|
| `push` | `refs/heads/my/branch` | `my-branch` |
|
||||||
|
| `push tag` | `refs/tags/v1.2.3` | `v1.2.3` |
|
||||||
|
| `push tag` | `refs/tags/v2.0.8-beta.67` | `v2.0.8-beta.67` |
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# event branch
|
||||||
|
type=ref,enable=true,priority=600,prefix=,suffix=,event=
|
||||||
|
# event tag
|
||||||
|
type=ref,enable=true,priority=600,prefix=,suffix=,event=
|
||||||
|
# event pr
|
||||||
|
type=ref,enable=true,priority=600,prefix=pr-,suffix=,event=
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=raw`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=raw,value=mytag1
|
||||||
|
type=raw,value=mytag2
|
||||||
|
# or
|
||||||
|
type=raw,mytag1
|
||||||
|
type=raw,mytag2
|
||||||
|
# or
|
||||||
|
mytag1
|
||||||
|
mytag2
|
||||||
|
```
|
||||||
|
|
||||||
|
Output custom tags according to your needs.
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=raw,enable=true,priority=200,prefix=,suffix=,value=mytag1
|
||||||
|
```
|
||||||
|
|
||||||
|
### `type=sha`
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
# minimal
|
||||||
|
type=sha
|
||||||
|
```
|
||||||
|
|
||||||
|
Output Git short commit as Docker tag like `sha-ad132f5`.
|
||||||
|
|
||||||
|
Extended attributes and default values:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tags: |
|
||||||
|
type=sha,enable=true,priority=100,prefix=sha-,suffix=
|
||||||
|
```

### Latest tag
|
### Latest tag
|
||||||
|
|
||||||
Latest Docker tag will be generated by default on `push tag` event. If for example you push the `v1.2.3` Git tag,
|
`latest` tag is handled through the [`flavor` input](#flavor-input). It will be generated by default (`auto` mode) for:
|
||||||
you will have at the output of this action the Docker tags `v1.2.3` and `latest`. But you can allow the latest tag to be
|
* [`type=ref,event=tag`](#typeref)
|
||||||
generated only if `tag-semver` is a valid [semver](https://semver.org/) or if Git tag matches a regular expression
|
* [`type=semver,pattern=...`](#typesemver)
|
||||||
with the [`tag-match` input](#tag-match-examples). Can be disabled if `tag-latest` is `false`.
|
* [`type=match,pattern=...`](#typematch)
|
||||||
|
|
||||||
### Handle semver tag
|
|
||||||
|
|
||||||
If Git tag is a valid [semver](https://semver.org/) you can handle it to output multi Docker tags at once.
|
|
||||||
`tag-semver` supports multi-line [Handlebars template](https://handlebarsjs.com/guide/) with the following inputs:
|
|
||||||
|
|
||||||
| Git tag | `tag-semver` | Valid | Output tags | Output version |
|
