Shutdown Kafka gracefully

This guide provides instructions to shut down Sasquatch Kafka as gracefully as possible before cluster interventions like OS or Kubernetes upgrades. To do so, 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
   

2. Terminate the Kafka Broker Pods. Ensure all brokers are stopped before proceeding.

   kubectl delete StrimziPodSet sasquatch-kafka-local-storage -n sasquatch
   

3. Terminate the Kafka Controller Pods.

   kubectl delete StrimziPodSet sasquatch-controller -n sasquatch
   

4. After the intervention, resume reconciliation of Strimzi resources. This will trigger the operator to start the Pods again.

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