NEW QUESTION # 13
You have a Deployment that runs a containerized application. The application requires access to a specific service running in a different namespace. You need to define a NetworkPolicy to allow traffic from the application's Pods to the service in the other namespace only on port 8080.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Network Policy Definition:
2. Explanation: - 'apiVersion: networking.k8s.io/v1 Specifies the API version for NetworkPolicy resources. - 'kind: NetworkPolicy': Specifies that this is a NetworkPolicy resource. - 'metadata.name: allow-service-access': Sets the name of the NetworkPolicy. - 'metadata.namespace: Specifies the namespace where the NetworkPolicy is applied. Replace with the actual namespace where your deployment is running. - 'spec.podSelector.matchLabels: app: application': This selector targets Pods labeled with 'app: application', ensuring the NetworkPolicy applies to the application Pods. - 'spec.egress.to.namespaceSelector.matchLabels: service-namespace: This allows outgoing traffic only to the namespace labeled with 'service-namespace: Replace with the actual namespace of the service. - 'spec.egress.ports.port: 8080': This allows communication only on port 8080. - 'spec.egress.ports.protocol: TCP': Specifies the protocol (TCP) for the allowed port. 3. How it works: - This NetworkPolicy allows outgoing traffic from the application Pods only to the specified service in the different namespace and only on port 8080. It effectively restricts communication from the application Pods to only the intended target service. 4. Implementation: - Apply the YAML using 'kubectl apply -f allow-service-access.yaml' 5. Verification: After applying the NetworkPolicy, test the connectivity from the application Pods to the service in the other namespace on port 8080. You should observe that the NetworkPolicy successfully enforces the restrictions, allowing access only to the specified port and service.]
NEW QUESTION # 14
You have a deployment that runs multiple replicas of a web server application. You need to ensure that the Deployment always maintains at least 2 replicas available, even if one or more pods are deleted or become unavailable. How can you configure the Deployment to achieve this using the 'maxUnavailable' field in the 'strategy.rollingUpdate' section?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Deployment with maxUnavailable': Define a Deployment YAML file with 'replicas: 3', indicating that you want three replicas of the web server application. Then, in the 'strategy.rollinglJpdate' section, set the 'maxUnavailable' field to '1'.
2. Apply the Deployment: Apply the YAML file to your cluster using 'kubectl apply -f my-web-server.yamr. The deployment will create three replicas of your web server application. 3. Test the 'maxUnavailable' Configuration: Delete or terminate one of the pods in the Deployment. The Deployment will automatically create a new pod to replace the deleted or unavailable one, ensuring that at least two replicas are always available. You can monitor the status of the deployment using 'kubectl get pods -l app=my-web-server'. You should see that two pods are consistently running, while the third is being replaced.
