- Build based on existing tags when needed
It will automatically generate buildkit configuration to use custom CA certificate if following conditions are met:

- File exists `/etc/docker/certs.d/<registry-value>/ca.crt`
> NB! To mount custom CA you can use Woodpecker CI runner configuration environment `WOODPECKER_BACKEND_DOCKER_VOLUMES` with value `/etc/ssl/certs:/etc/ssl/certs:ro,/etc/docker/certs.d:/etc/docker/certs.d:ro`. And have created file `/etc/docker/certs.d/<registry-value>/ca.crt` with CA certificate on runner server host.
