Hi David,

In this article, I didn’t use Red Hat OpenShift Container Platform but OKD in “test” (formerly OpenShift Origin) and indeed Network Manager is available in my CentOS 7 instance (as specified in this documentation =>

https://docs.okd.io/3.11/install/prerequisites.html#prereq-network-access).

When using Ansible playbooks to create an OpenShift cluster, this is automatically fixed normally =>

https://github.com/openshift/openshift-ansible/blob/master/roles/openshift_node/tasks/dnsmasq/network-manager.yml .

But if your goal is to create an extended cluster with several cloud providers, I invite you to read this excellent article about using OpenVSwitch with OpenShift =>

And for production, I don’t recommend using CentOS but rather RHEL 😉 …
