Question

You have deployed a stateless web application as a Deployment in a GKE Standard cluster. The application listens on port 8080, and you need to expose it to external internet users through a single stable external IP address that distributes TCP traffic across all the running Pods. What is the simplest way to accomplish this?

Accepted Answer

Create a Service of type LoadBalancer that targets the Deployment's Pods on port 8080.

Answer

Create a Service of type ClusterIP and access it using the node's internal IP address.

Answer

Create a Service of type NodePort and share the node's external IP and port with users.

Answer

Expose each Pod individually by assigning a static external IP to each Pod.
