hemanth22 / get-fluentd-running
Created December 4, 2021 13:47 — forked from portante/get-fluentd-running
A script to help get fluentd pods running on all labeled nodes of an OpenShift cluster; we need this because Kube currently does not support priority or preemption which we could use to ensure fluentd are always scheduled and run on properly labeled nodes.
#!/bin/bash
function finish {
rm -rf $TMPDIR
}
trap finish EXIT
TMPDIR=$(mktemp -d)
oc get nodes -o name > $TMPDIR/all-nodes
oc get nodes -o name -l logging-infra-fluentd=true > $TMPDIR/labeled-nodes
