## Use `.tags` file for tagging
Similarily to official
[drone-docker](https://github.com/drone-plugins/drone-docker) plugin you can use
`.tags` file to embed some custom logic for creating tags for an image.
```yaml
kind: pipeline
name: default
steps:
- name: build
image: golang
commands:
- go get
- go build
- make versiontags > .tags
- name: publish
image: banzaicloud/drone-kaniko
settings:
registry: registry.example.com
repo: registry.example.com/example-project
# tags: ${DRONE_COMMIT_SHA} <= it must be left undefined
username:
from_secret: docker-username
password:
from_secret: docker-password
```
## Test that it can build
```bash
