How to run docker service inside a Drone CI step?

We have a case we are migrating from Travis CI to Drone CI.

We could install docker-compose successfully, but as soon as we run docker-compose, it fails with an error saying the docker service is not up.

Part of logs:

+ chmod +x /usr/local/bin/docker-compose
+ docker-compose up -d
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Any way we can run docker and continue with docker-compose?
