질문 # 214
You have a Deployment that runs a web application. The application requires a specific version ot a library that is not available in the default container image. How would you use an Init Container to install this library before starting the main application container?
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create an Init Container:
- Add an 'initContainerS section to the Deployment's 'spec-template-spec' configuration.
- Define an Init Container with a suitable name (e.g., 'library-installer').
- Specify the image for the Init Container This image should contain the necessary tools and commands to install the required library.
- Replace 'your-library-installer-image:latest with the actual image you want to use.
2. Configure the Main Container: - In the main application container, ensure that the environment variable 'PATH' includes the installation directory of the library installed by the Init Container. - This allows the application to find and use the newly installed library. 3. Apply the Changes: - Apply the updated Deployment configuration using 'kubectl apply -t my-web-app-deployment.yamr. 4. Verify the Installation: - Once the Pods are deployed, you can check the logs of the main application container to confirm that the library is installed and available for use.

The pod for the Deployment named nosql in the craytisn namespace fails to start because its container runs out of resources.
Update the nosol Deployment so that the Pod:
1) Request 160M of memory for its Container
2) Limits the memory to half the maximum memory constraint set for the crayfah name space.

You have been tasked with scaling an existing deployment for availability, and creating a service to expose the deployment within your infrastructure.
Task
Start with the deployment named kdsn00101-deployment which has already been deployed to the namespace kdsn00101 . Edit it to:
* Add the func=webFrontEnd key/value label to the pod template metadata to identify the pod for the service definition
* Have 4 replicas
Next, create ana deploy in namespace kdsn00l01 a service that accomplishes the following:
* Exposes the service on TCP port 8080
* is mapped to me pods defined by the specification of kdsn00l01-deployment
* Is of type NodePort
* Has a name of cherry

질문 # 218
You nave a microservice tnat iS constantly updated With new features and bug fixes. You want to deploy new versions of this service in a way that minimizes downtime and avoids disrupting the existing application. Explain how you can use Kubernetes features to achieve this goal.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Deployment:
- Create a 'Deployment' object to manage your microservice.
- Specify the desired number of replicas and the container image.
- Use a 'rollinglJpdate' strategy to control the update process.
2. Control Rollout Pace: - Use the maxSurge' and 'maxlJnavailable' parameters to control the number of pods that can be unavailable or created during the update process. - For example, 'maxi-Inavailable: ensures that no pods are unavailable during tne update, while 'maxSurge: 1' allows for one extra pod to be created during the update. 3. Trigger Automatic Updates: - Use a 'Deployment's 'spec-template-spec-imagePullPolicy' to trigger updates automatically when a new image is available. - Set imagePullPolicy: Always' to force a pull of the image each time the deployment is updated. 4. Monitor Rollout Progress: - Use kubectl get pods -l app=my-microservice' to monitor the rollout progress. - You can also use tne 'kubectl rollout status deployment/my-microservice' command to get detailed information about the rollout. 5. Use Liveness and Readiness Probes: - Define liveness and readiness probes to ensure that containers are healthy and ready to serve traffic. - The 'Deployment' will automatically restart unhealthy containers, while readiness probes will ensure that new pods are only considered ready for traffic once they are healtny. 6. Traffic Routing: - Use a 'Service' to expose your 'Deployment' to external clients. - Configure the 'Service' to use a 'LoadBalancer' or 'NodePort' to make the service accessible from outside the cluster. Note: This approach ensures a smooth rollout with minimal downtime. New pods are created with the new image, and traffic is gradually shifted to the updated pods while the old pods are gracefully terminated. The liveness and readiness probes ensure that only healthy pods receive traffic, and the automatic updates triggered by 'imagePullPolicy: Always' keep the service up-to-date.
