# plugin-kaniko

A thin shim-wrapper around the official [Google Kaniko](https://github.com/GoogleContainerTools/kaniko) OCI image to make it behave similar to the [Drone Docker plugin](http://plugins.drone.io/drone-plugins/drone-docker/).

This is a fork of the discontinued [`drone-kaniko`](https://github.com/banzaicloud/drone-kaniko) by banzaicloud.

## Example .woodpecker.yml (pushing to Docker Hub):

```yaml
pipeline:
  build_and_release:
    image: gitea.mdg-hamburg.de/ci-tools/plugin-kaniko:debug
    pull: true
    settings:
      registry: registry.example.com # docker.io is the default registry
      repo: example-org/example-project
      tags: ${CI_COMMIT_SHA},awesometag,latest
	  cache: true
      dockerfile: Containerfile
      username:
        from_secret: container_registry_username
      password:
        from_secret: container_registry_password
```

## Example .drone.yml (pushing to Docker Hub):

```yaml
kind: pipeline
name: default

steps:
- name: build_and_release
  image: gitea.mdg-hamburg.de/ci-tools/plugin-kaniko
  settings:
    registry: registry.example.com # docker.io is the default registry
    repo: example-org/example-project
    tags: ${DRONE_COMMIT_SHA},awesometag,latest
    cache: true
    username:
      from_secret: docker-username
    password:
      from_secret: docker-password
```

## Pushing to Google Cloud Registry:


Instead of authenticating with username and password, you simply provide a json_key 
```yaml
...
  settings:
    json_key:
      from_secret: google_gcr_key
...
```

## Using auto-tag
**Woodpecker-only feature**

This uses the current git tag as the container destination tag. The `latest` tag is also appended. Optionally with the `tag_strip_v` a leading `v` can be stripped from the container tag.
```yaml
...
  settings:
    auto_tag: true
	tag_strip_v: false
...
```
