NEW QUESTION # 33
You have a complex application with multiple services running in a Kubernetes cluster. Some services communicate with each other over the cluster network, while others need to access external services over the internet. You need to configure CoreDNS to handle both internal and external DNS resolution in a secure and efficient manner.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Configure CoreDNS for Internal DNS:
- Create a CoreDNS ConfigMap named 'coredns' with the following configuration:
-

2. Configure CoreDNS for External DNS: - If you need to resolve external domains, you can use CoreDNS's 'forward' plugin to forward requests to external DNS servers. You can configure 'forward' in the Corefile, or use environment variables to dynamically set the upstream servers.

3. Configure Services with External Names: - If you need to access external services, configure their services in Kubernetes with the 'externalName' field.

4. Use Secure DNS: - Enable DNS over TLS (DOT) or DNS over HTTPS (DOH) in your CoreDNS configuration to ensure secure DNS resolution.

5. Test DNS Resolution: - Test DNS resolution for internal and external domains using the 'nslookup command from pods in your cluster.

NEW QUESTION # 34
You have a Deployment named 'my-app' with 5 replicas running an application container. You need to implement a rolling update strategy that allows for a maximum of 2 pods to be unavailable at any given time during the update process. Additionally, you want to ensure that the update process is triggered automatically whenever a new image is pushed to the Docker Hub repository 'my.org/my-app:latest'.

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 5.
- Define 'maxUnavailable: 2' 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.imagePullPolicy: Always' to ensure that the new image is pulled even if it exists in the pod's local cache.

2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f my-app.yamP 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments my-app' to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'my.org/my-app:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=my-app' to monitor the pod updates during the rolling update process. You will observe that up to 2 pods are terminated at a time, while new pods with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment my-app' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
