Optimize planned evacuation of a node in Red Hat OpenShift Container Platform

Solution In Progress - Updated -

Issue

  • We do maintenance on our nodes node by node, meaning we evacuate all pods, do our tasks. At the moment the --evacuate option immediately terminates all pods resulting in about 80-100 new pods which need to be scheduled, pulled and started. This also puts quite a lot of load on a lot of components (openshift, registry, nfs etc.). In our enviroment it took openshift between 5-15 minutes to fully restart and restore all pods. We know that applications should be scaled to more than one pod to minimize downtime. But a planned maintenance could be softer on the environment.

Environment
