Exposing Services in Kubernetes

With deployments, you can create a dynamically-managed set of replica pods. But this introduces a need for an equally dynamic way to access them. Services provide a layer of abstraction that provides access to pods and other entities, allowing dynamic, high-availability access to the necessary components of your applications. In this lab, you will have the opportunity to work with services by creating a service on top of an existing deployment.

  1. Challenge

    Create the `auth-svc` service

    Examine the auth-deployment. Take note of the labels specified in the pod template, as well as the containerPort exposed by the containers.

    kubectl get deployment auth-deployment -o yaml

    Create a service descriptor file called auth-svc.yml.

    apiVersion: v1
kind: Service
metadata:
  name: auth-svc
spec:
  type: NodePort
  selector:
    app: auth
  ports:
  - protocol: TCP
    port: 8080
    targetPort: 80

    Create the service in the cluster.

    kubectl apply -f auth-svc.yml

  2. Challenge

    Create the `data-svc` service

    Examine the data-deployment. Take note of the labels specified in the pod template, as well as the containerPort exposed by the containers.

    kubectl get deployment data-deployment -o yaml

    Create a service descriptor file called data-svc.yml.

    apiVersion: v1
kind: Service
metadata:
  name: data-svc
spec:
  type: ClusterIP
  selector:
    app: data
  ports:
  - protocol: TCP
    port: 8080
    targetPort: 80

    Create the service in the cluster.
