질문 # 204
You have a ConfigMap named 'database-config' tnat stores sensitive information for connecting to a database. You want to ensure that this ConfigMap is only accessible by a specific namespace and not by other namespaces in the cluster.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Namespace:
bash
kubectl create namespace my-database-namespace
2. Move the ConfigMap to the Namespace:
bash
kubectl move configmap database-config -n my-database-namespace
3. Configure Role-Based Access Control (RBAC):
- Create a Role:
- Create a RoleBinding:
- Replace 'my-service-account with the actual name of the service account that needs access to the ConfigMap. 4. Apply the Role and Role3inding: bash kubectl apply -f database-config-reader.yaml kubectl apply -f database-config-reader-binding.yaml 5. Verify Access: - From the 'my-database-namespace': bash kubectl get configmap database-config -n my-database-namespace The command should succeed as the service account in this namespace has the necessary permissions. - From a different namespace: bash kubectl get configmap database-config -n another-namespace This command should fail as the service account in this namespace does not have access to the ConfigMap. This solution uses RBAC to restrict access to the ConfigMap to only the service account in the 'my-database-namespace'. This ensures that sensitive information is only accessible by authorized entities within the cluster,

Developers occasionally need to submit pods that run periodically.
Task
Follow the steps below to create a pod that will start at a predetermined time and]which runs to completion only once each time it is started:
* Create a YAML formatted Kubernetes manifest /opt/KDPD00301/periodic.yaml that runs the following shell command: date in a single busybox container. The command should run every minute and must complete within 22 seconds or be terminated oy Kubernetes. The Cronjob namp and container name should both be hello
* Create the resource in the above manifest and verify that the job executes successfully at least once See the solution below.

질문 # 206
You have a Deployment named 'mysql-deployment running a MySQL database container. The 'mysql-deployment' has 2 replicas and you want to implement a blue-green deployment strategy for updating the database. The following steps need to be implemented:
- Create a new Deployment called 'mysql-deployment-new' with the updated MySQL image.
- Ensure that both deployments (old and new) are running concurrently.
- Route traffic to the 'mysql-deployment-new' deployment.
- Remove the old deployment ('mysql-deployment) once the traffic is switched over.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a new Deployment with updated image:
- Create a new Deployment named 'mysql-deployment-new' with the updated MySQL image. You can either create a new YAML tile or use 'kubectl create deployment' command.
- Ensure that the new deployment has the same number ot replicas as the old deployment.
2. Apply the new Deployment: - Apply the new Deployment YAML using 'kubectl apply -f mysql-deployment-new.yamr 3. Check Deployment status: - IJse ' kubectl get deployments' to verity that both deployments are running. You should see both 'mysql-deployment' and 'mysql-deployment-new' . 4. Update Service to use the new deployment: - Update the Service that is associated with the MySQL database to point to the new Deployment
- Apply the updated Service YAML using 'kubectl apply -f mysql-service-yamr 5. Verify traffic routing: - Test the application or services that rely on the MySQL database to ensure that the traffic is now being routed to the 'mysql-deployment-new' 6. Delete old Deployment: - Once you have verified that the traffic is successfully routed to the new Deployment, you can delete the old Deployment 'mysql-deployment' using 'kubectl delete deployment mysql-deployment'.]
질문 # 207
You are building a microservice architecture for a new e-commerce application. This architecture consists of three microservices: 'product- service' , 'can-service' , and 'order-service'. Each microservice nas a dedicated database and utilizes a Redis cacne for performance optimization.
You are tasked with designing the 'product-service , which is responsible for managing product information (name, description, price, inventory).
Implement a multi-container Pod design for the product-service' that addresses the following requirements:
- The Pod must include a primary container running the 'product-service' application.
- The Pod must include a secondary container for Redis to cache frequently accessed product data.
- The Pod must use a shared volume to persist the Redis data across container restarts.
- The 'product-service' must connect to the local Redis instance in the Pod for optimized data retrieval.
- The product-service' should be configured to periodically update the Redis cache With the latest product data from the database.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the Deployment YAML:
- Define a Deployment with the name 'product-service'
- Set the replicas to ' 2' to provide redundancy and high availability.
- Specify the labels Sapp: product-service' for selecting the Pods in the Deployment.
- Create a 'template' section to define the Pod specification.
2. Create the Persistent Volume Claim (PVC): - Define a PVC with the name 'redis-pvc' - Specify the storage class and access mode. - Set the required storage size for Redis data.
3. Deploy the Resources: - Apply the Deployment and PVC using 'kubectl apply -f deployment.yamr and 'kubectl apply -f pvc.yamr. 4. Verify the Deployment: - Check the status of the Deployment using 'kubectl get deployments product-service' and ensure that two Pods are running. - Check the status of the PVC using 'kubectl get pvc redis-pve 5. Configure the 'product-service'- - Modify the 'product-service' application to use the Redis instance in the Pod as the cache backend. - Configure the -product-service' to periodically tetch data trom the database and update the Redis cache. 6. Test the Application: - Send requests to the 'product-service to retrieve product data. - Monitor the Redis cache to ensure that it's being used and updated as expected. Important Considerations: - Ensure that the 'product-service' application is properly configured to connect to the Redis instance within the same Pod. - Use a suitable Redis cache library or framework in the 'product-service for efficient caching. - Implement a proper caching strategy (e.g., TTL, cache eviction) to prevent stale data. - Monitor the Redis cache performance and resource usage to optimize the cache configuration.

Context
Anytime a team needs to run a container on Kubernetes they will need to define a pod within which to run the container.
Task
Please complete the following:
* Create a YAML formatted pod manifest
/opt/KDPD00101/podl.yml to create a pod named app1 that runs a container named app1cont using image Ifccncf/arg-output with these command line arguments: -lines 56 -F
* Create the pod with the kubect1 command using the YAML file created in the previous step
* When the pod is running display summary data about the pod in JSON format using the kubect1 command and redirect the output to a file named /opt/KDPD00101/out1.json
* All of the files you need to work with have been created, empty, for your convenience
