We have installed Openshift Container Platform 3.6 on RHEL7.4, Docker 1.12.6 using Ansible playbook. Installation got completed successfully.
After installation when we are trying to deploy any application (like " oc new-app rails-pgsql-persistent") we are getting below error.
Have checked and Router and Docker-regisrty pods are running fine.
