Openshift nodes

You can deploy OpenShift Container Platform with no worker nodes on a bare metal cluster. In this case, the master nodes are marked schedulable by default. You can allow or disallow master nodes to be schedulable by configuring the mastersSchedulable field. Procedure Edit the schedulers.config.openshift.io resource. The purpose of the Masters is to provide the API and Controllers services and, if possible, make them non-schedulable. Those masters will take care of: Handling requests from clients (Nodes, Users, Admins and other infrastructure systems deployed on Openshift) Run the Scheduler and Replication Controller. Provide Client tools (oc and oadm)OpenShift is a cloud development Platform as a Service (PaaS) hosted by Red Hat.
