AMQ Streams / Strimzi Training - Lab 8

Check the cluster deployment in templating/kafka.yaml
- Notice the template fields with their definitions of labels and annotations
- For pods we also define the termination grace period which defines how much time do we give to the pods to terminate
- Missing in this examples are image pull secrets and security context
Apply the Kafka resource
- oc apply -f templating/kafka.yaml
Check the labels and annotations assigned to the different resources such as services, pods, etc.
- oc get services -o='custom-columns=NAME:.metadata.name,LABELS:.metadata.labels,ANNOTATIONS:.metadata.annotations'
On your own
- Try to use some other customization such as Security Context or Image Pull Secrets
Delete the Kafka cluster
- oc delete kafka my-cluster

Check the cluster deployment in jbod/kafka.yaml
- Notice the storage section in .spec.kafka
- It defines two persistent disks
Apply the Kafka resource
- oc apply -f jbod/kafka.yaml
Check the volumes which were created
- You should see 6 Persistent Volume Claims (+3 for Zookeeper): oc get pvc
- You should see 6 Persistent Volume (+3 for Zookeeper): oc get pv | grep Bound
- Exec into the pod and check how the volumes are mounted and configured
  - Open a terminal inside the pod oc exec -ti my-cluster-kafka-0 -- bash
  - Check the /var/lib/kafka directory and the configuration file in /tmp/strimzi.properties (look for the log.dirs property)
Delete the Kafka cluster
- oc delete kafka my-cluster
