Create a Service

Overview

In Kubernetes, a Service is a resource for exposing and accessing applications. It provides a stable network endpoint so that clients inside or outside the cluster can reach the application running in Pods. A Service uses a selector to route requests to backing Pods, and provides load balancing and service discovery.

Inside VKS, a Service is only reachable from within the cluster. To expose it on the public network, publish the service.

Deploy a Service

Deploying a Service in Kubernetes typically involves two steps:

• Create a Deployment to manage the application's Pods
• Create a Service to expose those Pods

Example

# vcluster service exposure
apiVersion: v1
kind: Service
metadata:
  name: your-service-name
  namespace: your-namespace
spec:
  selector:
    app: your-app-name  # the app label of your Pod
  type: ClusterIP
  ports:
    - port: 8000        # service port
      protocol: TCP
      targetPort: 8000  # container port inside your Pod
