Elastic load balancer as LoadBalancer service

Let's create a LoadBalancer Service with Pods underneath, which is what we learned in Chapter 3, Playing with Containers:

# cat aws-service.yamlapiVersion: apps/v1kind: Deploymentmetadata:  name: nginxspec:  replicas: 3  selector:    matchLabels:      run: nginx  template:    metadata:      labels:        run: nginx    spec:      containers:        - image: nginx          name: nginx          ports:            - containerPort: 80---apiVersion: v1kind: Servicemetadata:  name: nginxspec:  ports:    - port: 80      targetPort: 80  type: LoadBalancer  selector:    run: nginx

In the preceding template, we declared one nginx Pod and associated it with the LoadBalancer service. The service will direct the packet to container port 80:

# kubectl create -f aws-service.yaml deployment.apps ...
