Shutdown Kafka gracefully

It is recommended that you shut down Kafka gracefully before cluster interventions like OS or Kubernetes upgrades. To shut down Kafka gracefully, follow these steps:

1. Pause reconciliation of Strimzi resources. This will prevent the operator from restarting the pods after they are deleted.

   kubectl annotate --overwrite Kafka sasquatch strimzi.io/pause-reconciliation="true" -n sasquatch
   kubectl annotate --overwrite KafkaConnect sasquatch strimzi.io/pause-reconciliation="true" -n sasquatch
   

2. Shut down Kafka and KafkaConnect pods.

   kubectl delete StrimziPodSet sasquatch-connect sasquatch-controller sasquatch-kafka -n sasquatch
   

3. After the intervention, resume reconciliation of Strimzi resources. This will allow the operator to restart the pods.

   kubectl annotate --overwrite Kafka sasquatch strimzi.io/pause-reconciliation="false" -n sasquatch
   kubectl annotate --overwrite KafkaConnect sasquatch strimzi.io/pause-reconciliation="false" -n sasquatch
