질문 # 33
You are deploying a new application named 'ecommerce-app' that requires 10 replicas. You want to implement a rolling update strategy that ensures only two pods are unavailable at any given time, while also allowing for the creation of three new poos simultaneously.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAMLI
- Update the 'replicas to 10.
- Define 'maxiJnavaiIabIe: 2 and 'maxSurge: 3' in the 'strategy.roIIingLJpdate section.
- Configure a 'strategy-type' to 'RollinglJpdate' 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 ecommerce-app-deployment.yaml' 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments ecommerce-app-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'example/ecommerce-app:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=ecommerce-apps to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while three new pods with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment ecommerce-app-deployment to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
질문 # 34
You are building a web application that uses a set of environment variables for configuration. These variables are stored in a ConfigMap named 'app-config' . How would you ensure that the web application pods always use the latest version of the ConfigMap even when the ConfigMap is updated?
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the ConfigMap: Define the ConfigMap with your desired environment variables.
2. Update the Deployment: Modify your Deployment YAML file to: - Use a 'volumeMount' to mount the ConfigMap into the container. - Specify a 'volume' using a 'configMap' source, referencing tne 'app-config' ConfigMap. - Set 'imagePullPolicy: Always' to ensure the pod always pulls the latest container image.
3. Apply the changes: Use 'kubectl apply -f deployment-yamp to update the Deployment 4. Llpdate the ConfigMap: Whenever you need to update the configuration, modify the Sapp-config' ConfigMap using 'kubectl apply -f configmap-yamr 5. Verify changes: Observe the pods for the 'web-app' Deployment. They should automatically restart and pick up the new environment variables from the updated ConfigMap. By setting 'imagePullPolicy: AlwayS , your pods will always pull the latest container image- This ensures that the pod's container always uses the latest code. Additionally, the 'volumeMount' and 'volume detinitions mount tne Sapp-config' ConfigMap into the containers 'letc/config' directory, making the environment variables accessible within the container When you update the ConfigMap, the pod will detect the change and automatically restart, loading the new configuration from the updated ConfigMap. ,
질문 # 35
You have a Kustomization file that applies a patch to the 'spec-template-spec-containers-image' field of a Deployment However, you are now using a newer version of Kubernetes and have received warnings about the deprecated 'spec.template.spec' path. How can you update the Kustomization file to use the recommended API path, ensuring the patch still applies correctly?
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Identify the Deprecated Path: The original Kustomization file likely has a patch like this:
Where 'patch.yamr contains:
2. IJpdate the Patch Path: Replace the deprecated path with the recommended one: Vspec/template/spec.containers/0/image' -> /spec/template.container/0/images
3. Apply the IJpdated Kustomizatiom Re-apply the Kustomization file With the updated patch. 4. Verify the Patch: Verify that the updated Deployment now uses the new image by checking the 'spec-template.spec.contajners.image' field. This example demonstrates updating a Kustomization file to use the correct API path for a patch. It is important to regularly review Kustomization files and apply any necessary updates to avoid issues with API deprecations and ensure compatibility with the latest Kubernetes versions.,
