## "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 proprely so it performed restart to the Pod`
