How can I find out which version of Docker serves inside an OpenShift cluster when I am not able to execute oc describe node (presumably because mine is not an admin account). Or does OpenShift 3.11 use a well-known default version of Docker (similar to its well-known use of Kubernetes 1.11).
Per OCP is supported the specific Docker version. The Docker version is 1.13.1 on OCPv3.11. Refer here.
