FluentBit does not start on AKS after upgrade to logging-operator:6.1.0 #2123
Description
Describe the bug:
After upgrading to logging-operator 6.1.0 (from 6.0.3) the FluentBit pods do not start anymore.
We are using AKS v1.33.3 and the deployment is done via Helm-Chart. With the old logging-operator version 6.0.3 FluentBit just works fine.
Expected behaviour:
FluentBit should work
Steps to reproduce the bug:
Deployment of the latest logging-operator version (6.1.0) on K8s 1.33.3
