Verify the Deployment: - Check the status of the deployment using get deployments myapp-deploymen. - Ensure that three pods are running and that the liveness probe is monitoring their health. You can use 'kubectl describe pod myapp-deployment-XXXX' (where XXXX is the pod name) to see the details of the pod and the liveness probe status.
