Expose Pod in Kubernetes

Introduction 

Today we will learn to expose the Pod Resource of Kubernetes.

Expose Pod

We will create and expose the pod using below yaml:

apiVersion: v1
kind: Pod
metadata:
  name: ashok-pod
  labels:
    app: web
spec:
  containers:
    - name: hello-app
      image: gcr.io/google-samples/hello-app:1.0
      ports:
      - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: ashok-svc
spec:
  type: LoadBalancer
  ports:
  - port: 8080
    targetPort: 8080
  selector:
    app: web

We will create the pod and service using:

$ kubectl apply -f pod2.yaml
pod/ashok-pod created
service/ashok-svc created

We can status using below:

$ kubectl get all
NAME            READY   STATUS    RESTARTS   AGE
pod/ashok-pod   1/1     Running   0          92s

NAME                 TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
service/ashok-svc    LoadBalancer   10.108.156.134   <pending>     8080:30901/TCP   92s
service/kubernetes   ClusterIP      10.96.0.1        <none>        443/TCP          3d2h

Create a tunnel to access service in browser:

$ minikube tunnel
🏃  Starting tunnel for service ashok-svc.

Open the browser  http://localhost:8080/ :

Happy Coding !!
