KUBERNETES: Deploy Sample nginx Weblogic (from Docker.io) to Kubernetes Cluster For Testing

1) Create nginx deployment yaml file. For e.g. nginx.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-webapp
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-webapp
  template:
    metadata:
      labels:
        app: my-webapp
    spec:
      containers:
      - name: my-webapp
        image: nginx:1.7.9
        ports:
        - containerPort: 80

2)Create nginx service yaml file to listen on the Nodeport. For e.g. nginx-service-nodeport.yaml

apiVersion: v1
kind: Service
metadata:
  name: my-webapp-service
spec:
  selector:
    app: my-webapp
  ports:
  - port: 80
    targetPort: 80
    nodePort: 30007
  type: NodePort

3) Deployment the nginx webapp and create service. 

kubectl apply -f nginx.yaml

kubectl apply -f nginx-service-nodeport.yaml

4) Check the deployment and service are created in default namespace.

For this run below command.

kubectl get all

Below is sample output.

deployment.apps/my-webapp   3/3     3            3           8m19s

NAME                                   DESIRED   CURRENT   READY   AGE
replicaset.apps/my-webapp-6c854bcc4c   3         3         3       8m19s

5) Acccess the nginx webapp using nodeport 30007 and Kubernetes machine IP where pod is running.

http://IP:30007
