Error on the Rancher server UI side
[workerPlane] Failed to bring up Worker Plane: Failed to create
[kubelet] container on host [ip-address]: Error response from daemon: invalid mount config: must use either propagation mode "rslave" or

Docker Version: Docker version 17.12.1-ce OS: Centos 7
At the time of writing, 17.03 is the latest version of Docker officially supported by K8S/Rancher, and is the latest version from Centos repositories that will function without this error.
However, if you pull from EPEL, docker-ce-17.12.0 will also work.
