Kubernetes: A Stable Address for Moving Pods

MediumDevOps15-20 min

The brief

A Deployment's Pods (in /root/case/deployment.yaml for reference) keep getting replaced with new IPs, so clients can't target them directly. Write a Service manifest at /root/case/service.yaml that gives them one stable virtual IP and DNS name. Read /root/case/assignment.env for the app label (APP) the Service must select and the service port (PORT) it must expose. The Service needs kind: Service, a selector matching the Pods' app label, and that port. Grading reads the manifest YAML.

What you'll do

Declare a Service (kind: Service)
Select the Pods by their app label (spec.selector)
Expose the assigned service port
