Cannot connect to the Docker daemon at tcp://localhost:2375/invalid.sock. Is the docker daemon running?This error message is quite confusing, as the original invalid DOCKER_HOST value does not contain tcp://localhost:2375.
Probably it should return an error like invalid $DOCKER_HOST value "/invalid.sock": must start with "unix://" or "tcp://"
