You have a Kubernetes cluster with two worker nodes and a single Nginx service deployed. You want to expose this service externally using a LoadBalancer service type but only want traffic to be directed to pods on a specific worker node. How would you achieve this?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Node Selector:
- Create a Node Selector label on the worker node where you want to host the Nginx pods.
- Example:
- Apply this configuration using 'kubectl apply -f node-config.yaml'. 2. Configure the Deployment: - Update the Nginx deployment to include the Node Selector label in its pod template. - Example:
- Apply the updated deployment configuration using 'kubectl apply -f nginx-deployment.yamr. 3. Create a LoadBalancer Service: - Create a LoadBalancer type service that selects the Nginx pods with the 'app=nginx' label. - Example:
- Apply the service configuration using 'kubectl apply -f nginx-service.yamP. 4. Verify the Deployment: - Confirm the deployment of the Nginx pods on the specified worker node using 'kubectl get pods -l app=nginx -o wide'. - Check the LoadBalancer service's external IP address using 'kubectl get services nginx-service'. - Access the Nginx service using the external IP address. All traffic should be routed to the pods on the worker node with the 'worker-type: nginx' label. ---
