Section Number and Name:
section: Configuring Schedulability on Masters
Describe the issue:
I have a 2 node openshift 3.7 cluster which became unresponsive because I was running etcd on the same node as my (ML) machine learning application. My ML application starved etcd of memory and cpu caused etcd to become "dead" as returned from
"systemctl status etcd"
Suggestions for improvement:
Instead of this warning which is currently in the installation guide:
"You can manually set a master host to schedulable during installation using the openshift_schedulable=true host variable, though this is not recommended in
State that it is "IMPORTANT* not to run etcd and other master services on the same node as user pods.
