"Killing" Containers - Solution

1. Run Pod with a web service (e.g. httpd) - kubectl run web --image registry.redhat.io/rhscl/httpd-24-rhel7
2. Verify the web service is running with the ps command - kubectl exec web -- ps
3. Check how many restarts the pod has performed - kubectl get po web
4. Kill the web service process -kubectl exec web -- kill 1
5. Check how many restarts the pod has performed - kubectl get po web
6. Verify again the web service is running - kubectl exec web -- ps

After you complete the exercise

• Why did the "RESTARTS" count raised? - because we killed the process and Kubernetes identified the container isn't running properly so it performed restart to the Pod
