Description Seth Jennings 2019-06-14 20:42:24 UTC 
While verifying a fix for another bug, I found this
https://bugzilla.redhat.com/show_bug.cgi?id=1650196#c7

Adding a NoExecute taint to a node in 3.11 will cause the node-exporter DS pod on that node to be evicted.  This is not what we want.

Fix is the same as 1650196; tolerating all taints in the node-exporter pod template.

See https://github.com/openshift/openshift-ansible/pull/10731/files for example.
