Solution Verified - Updated -


  • We have pods running on the master node even though scheduling is disabled:
# oc get nodes

# oc get pods -o wide --all-namespaces | grep master

test                                another-example-pod-3-ffjae                                   1/1       Running            0          3d      master.example.com
  • I marked a node unschedulable with below command but pod continues to run there:
# oc adm manage-node <nodename> --schedulable=false
  • I cordoned a node but continue to run pod deployments there
