Open-source docker image availability

When using the example include `docker-compose.yaml` file, it builds the API server locally and is able to boot up. When using the dockerhub image available on https://hub.docker.com/r/appbaseio/reactivesearch-api, it fails to boot asking for a valid `APPBASE_ID`.

Could this be happening because of the build args not being opensource? https://github.com/appbaseio/reactivesearch-api/blob/dev/Dockerfile#L3-L18

My modified docker-compose file:
