Images to consider as [cache sources](https://docs.docker.com/engine/reference/commandline/buildx_build/#cache-from). To properly work,
commas used in the cache source entries need to be escaped:
```Yaml
- name: Build
image: thegeeklab/drone-docker-buildx:20
settings:
repo: example/repo
cache_from:
# using quotes double-escaping is required
- "type=registry\\\\,ref=example"
- 'type=foo\\,ref=bar'
```
