spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:

    spec:
      containers:
      - name: nginx
        image: nginx:1.14.0
        ports:
        - containerPort: 80

nginx-deployment.yaml

kind: Service
apiVersion: v1
metadata:
  name: nginx-service
spec:
  selector:
    app: nginx
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80

nginx-service.yaml
