RancherOS on AWS: Cannot connect to the Docker daemon


I am using RancherOs on AWS through the latest AMI. I have not made any specific configuration.
When ssh-ed on the machine, docker run commands fail with Cannot connect to the Docker daemon. Is the docker daemon running on this host?
/var/log/docker.log dosn’t show anything strange:
