From 2967d963d5185d7e77fe9b235886deaf64534a3c Mon Sep 17 00:00:00 2001 From: Monis Khan Date: Fri, 6 Oct 2017 11:06:50 -0400 Subject: Switch to configmap leader election on 3.7 upgrade This change sets the controllerConfig.election.lockName to openshift-master-controllers on a 3.7 upgrade. This is the default in a new 3.7 cluster. Important excerpt from the docs inside the origin codebase (slightly modified): There are two modes for lease operation - a legacy mode that directly connects to etcd, and the preferred mode which coordinates on a configmap or endpoint in the kube-system namespace. Because legacy mode and the new mode do not coordinate on the same key, an upgrade must stop all controllers before changing the configuration and starting controllers with the new config.
