Multiple Network Interfaces Causing OpenShift Install Errors

Solution Unverified - Updated -

Issue

  • OpenShift install issue - nodes wont register, dnsmasq is not configured to openshift_ip, sdn connectivity issues
  • Physical nodes each have 2 net connections/interfaces (one 'management' interface for SSH, etc. and one 'openshift' interface)
  • For our ansible inventory file, all nodes have the openshift_ip set to the 'openshift' network ip corresponding to that system.
  • The playbook fails while trying to register the nodes. When I login to the physical systems, dnsmasq is listening on the 'management' network instead of the 'openshift' network since that is how ansible configured
  • node-config file also has dnsIP as 'management' instead of 'openshift'
  • If I manually make dnsmasq changes and atomic-openshift-node changes for the dnsIP and restart, the node will register

Environment

  • Red Hat OpenShift Container Platform
