Hi Team
We recently upgraded our AKS cluster from 1.28.5 to 1.29.4 . The apache nifi - version 1.16.3 was already installed in it and running successfully. After the upgrade to 1.29.4 , one of the Pod - Nifi was continuously restarting and goes to Crashloopbackoff. When we investigate, the server container keeps restarting and there were no logs showing any error as it is changing status to Running and then to Not ready very quickly and pod reports Crashloopbackoff. We are also unable to login inside the pod due to this. At times when the status is running , it is allowing to connect for few seconds and we noticed that the KeyStore.jks and truststore,jks from certmanager is not present within tls folder.
We are not sure what is the cause of the continuous restart of the server container after upgrade of aks cluster to 1.29.4
when we compared the logs of the nifi-0 and nifi-1 pod, the nifi -0 pod showing below log and running successfully. Whereas nifi-1 and nifi-2 do not have these logs.
/opt/nifi/nifi-current/tls/truststore.jks is not readable! Waiting for cert-manager sidecar to populate it.
Could you please help share some inputs to resolve this issue ?
Best Regards
