NEW QUESTION # 81
You have a Deployment running an application that requires a specific network policy. How can you define a network policy that allows only traffic from Pods belonging to the same namespace as the application and denies all other traffic?

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-same-namespace': 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: {F: This empty podSelector means the NetworkPolicy applies to all Pods in the namespace. - 'spec.ingress': This section defines the rules for incoming traffic. - 'spec.ingress.from.podSelector: {F: This allows traffic from any Pods within the same namespace. 3. How it works: - This NetworkPolicy allows incoming traffic only from Pods within the same namespace where the Deployment is running. It explicitly denies all other traffic, effectively isolating the application to communication only within its namespace. 4. Implementation: - Apply the YAML using 'kubectl apply -f allow-same-namespace.yaml' 5. Verification: After applying the NetworkPolicy, test the communication between Pods within the same namespace and Pods in other namespaces. You should observe that the NetworkPolicy successfully enforces the defined restrictions.

NEW QUESTION # 82
You need to deploy a microservice application that uses a custom DNS service for internal communication between microservices. This DNS service is not a standard Kubernetes DNS service. How would you configure Kubernetes to use your custom DNS service for the internal communication of your application?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ConfigMap for DNS Configuration:
- Create a ConfigMap to store the DNS configuration details for your custom DNS service.
- Example:

- Replace '10.0.0.1 ,10.0.0.2 with the IP addresses of your custom DNS servers and 'my-app.svc.cluster.local' with the search domain for your application. 2. Create a DaemonSet for DNS Configuration: - Create a DaemonSet that will inject the custom DNS configuration into all pods in your cluster. - Example:

- This DaemonSet will use a 'busybox' container to write the DNS configuration from the 'custom-dns-config' ConfigMap to the '/etc/resolv.conf file in every pod. 3. Deploy your Application: - Deploy your microservice application with the appropriate labels to ensure that the DaemonSet injects the custom DNS configuration into your application's pods. 4. Verify DNS Resolution: - Verify that your application's pods can resolve internal DNS names using your custom DNS service. - Example: - You can use the 'nslookup command within a pod to test DNS resolution. 5. Configure Security: - Implement appropriate security measures to protect your custom DNS service and prevent unauthorized access to your application's internal services. - Example: - Consider using a firewall to restrict access to the custom DNS servers. - Configure access control lists to limit access to the DNS service.
