NEW QUESTION # 52
You have a Deployment named 'web-app' with 3 replicas running a Flask application. You need to implement a rolling update strategy that ensures only one pod is unavailable at any time. Additionally, you need to implement a strategy to handle the update process when the pod's resource requests exceed the available resources.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAML:
- Update the 'replicas' to 2.
- Define 'maxUnavailable: 1' and 'maxSurge: 0' in the 'strategy.rollingUpdate' section to control the rolling update process.
- Configure a 'strategy.type" to 'RollingUpdate" to trigger a rolling update when the deployment is updated.
- Add a 'spec.template.spec.resources' section to define resource requests for the pod.
- Set 'spec.template.spec.restartPolicy' to 'OnFailure' for the pod to restart when it fails.

2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f web-app.yaml' 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments web-app' to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Update the 'web-app' image in the Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=web-app' to monitor the pod updates during the rolling update process. You will observe that one pod is terminated at a time, while one new pod with the updated image is created. 6. Handle Resource Exceedance: - If the pod's resource requests exceed the available resources, the pod will be evicted and restarted. The 'restartPolicy' ensures that the pod restarts automatically upon failure. 7. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment web-app' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.

NEW QUESTION # 53
Create a pod that echo "hello world" and then exists. Have the pod deleted automatically when it's completed

Answer:

Explanation:
kubectl run busybox --image=busybox -it --rm --restart=Never -- /bin/sh -c 'echo hello world' kubectl get po # You shouldn't see pod with the name "busybox"

NEW QUESTION # 54
You are setting up a new Kubernetes cluster with a highly sensitive application that requires access control at the pod level. Explain how you can use NetworkPolicy to restrict access to pods within your cluster.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a NetworkPolicy Resource: Define a 'NetworkPolicy' resource using a YAML file. The
'NetworkPolicy' resource will contain the rules for network traffic access to the pods. You can use 'kubectl create -f networkpolicy.yaml' to create the NetworkPolicy resource.

2. Set 'podSelectoo: Use the podSelector' field to identify the pods that will be affected by the policy. In this example, we are targeting pods with the label 'app: sensitive-app'. 3. Define 'ingress' and 'egress' Rules: Use the 'ingress' and 'egress' sections to define the rules for incoming and outgoing traffic. 'ingress': This section specifies which pods or services are allowed to send traffic to the pods targeted by the 'NetworkPolicy'. Here, we are allowing traffic from pods labeled app: trusted-service'. 'egress': This section specifies which destinations the pods targeted by the NetworkPolicy are allowed to send traffic to. In this example, we are allowing egress traffic to the IP address range 10.0.0.0/16. 4. Implement the "NetworkPolicy': Apply the YAML file using 'kubectl apply -f networkpolicy.yaml'. Once applied, the NetworkPolicy will be enforced, blocking any traffic that does not meet the specified rules.
