- while creating ACLs in the initContainer in the daemonset, change the default user and group of the otel image to 999 (this is because splunk-otel-collector has uid of 999) - add post delete hook which deletes ACLs set for directories used by agent, gateway and clusterReceiver while those pods run as non-root users --------- Co-authored-by: omrozowicz-splunk <[email protected]>
