NEW QUESTION # 70
You have a Deployment that runs a containerized web application. The web application depends on a specific database service running on a different node in the cluster. The web application should only be able to connect to the database service on port 5432 and not any other services running on the database node. How can you define a NetworkPolicy to achieve this?

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-database-access': Sets the name of the NetworkPolicy. - 'metadata.namespace: Specifies the namespace where the NetworkPolicy is applied. Replace with the actual namespace where your web application Deployment is running. - 'spec.podSelector.matchLabels: app: web-app': This selector targets Pods labeled with 'app: web-app', ensuring the NetworkPolicy applies to the web application Pods. - 'spec.ingress.from.podSelector.matchLabels: app: database': This allows incoming traffic only from Pods labeled with 'app: database'. - 'spec.ingress.ports.port: 5432': This allows communication only on port 5432. - 'spec.ingress.ports.protocol: TCP': Specifies the protocol (TCP) for the allowed port. 3. How it works: - This NetworkPolicy allows the web application Pods to connect only to the database service Pods on port 5432. It denies all other traffic from the database node, including other services that might be running on that node. 4. Implementation: - Apply the YAML using 'kubectl apply -f allow-database-access.yaml' 5. Verification: After applying the NetworkPolicy, test the connectivity from the web application Pods to the database service on port 5432 and to other services on the database node. You should observe that the NetworkPolicy effectively enforces the restrictions, allowing access only to the specified database port.
