NEW QUESTION # 85
You have a Deployment named 'my-app-deployment' that runs 3 replicas of an application container. The application container requires access to a ConfigMap named 'my-app-config' . You want to configure your Deployment to use Kustomize to automatically update the ConfigMap's data within the containers whenever the ConfigMap is updated. You also need to configure a rolling update strategy for the Deployment that allows for a maximum of one pod to be unavailable during the update process.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ConfigMap with the necessary data:

Apply tne ConfigMap using 'kubectl apply -f my-app-config.yaml' 2. Create a Kustomization file for your Deployment:

This file defines the resources that Kustomize will manage and the patch file to apply 3. Create a patch file to reference the ConfigMap:

This patch adds a 'envFrom' section to the container, referencing the 'my-app-config' ConfigMap. 4. Create your Deployment YAML file:

5. Apply the Kustomize configuration: - Navigate to the directory containing your Kustomization file. - Run the command 'kustomize build' to build the Kustomize resources. - Apply the built resources using 'kubectl apply -f kustomization_yaml' 6. Update the ConfigMap: Modify the data within the 'my-app-config' ContigMap. You can either edit the YAML file directly or use 'kubectl patch' to update specific values. 7. Verify the update: - Observe the logs of your 'my-apps containers to confirm that the environment variable has been updated with the new ConfigMap data. - Use 'kubectl get pods -l app=my-app' to monitor the rolling update process. You should see one pod at a time being updated with the new ConfigMap data. Note: The rolling update strategy ensures that only one pod is unavailable at a time during the update process, minimizing downtime. Kustomize ensures that the ConfigMap changes are automatically applied to the Deployment, keeping your application up-to-date.]


NEW QUESTION # 86
You are deploying a new application named 'streaming-services that requires 7 replicas. You want to implement a rolling update strategy that allows for a maximum of two pods to be unavailable at any given time. However, you need to ensure that the update process is triggered automatically whenever a new image is pusned to the Docker Hub repository 'streaming/streaming-service:latest'.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Update the Deployment YAMI-:
- Update the 'replicas' to 7.
- Define 'maxunavailable: 2" and 'maxSurge: (Y in the 'strategy.rollingUpdate' section.
- Configure a 'strategy.types to 'Rollingl_lpdates 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 streaming-service-deployment-yamr 3. Verify the Deployment - Check the status of the deployment using 'kubectl get deployments streaming-service-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'streaming/streaming-service:latest' Docker Hub repository. 5. Monitor the Deployment - Use 'kubectl get pods -l app=streaming-service' to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while two new with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment streaming-service-deployment' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
