Nginx DeploymentとService(type: loadbalancer)を動作させるサンプル。

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 2 # tells deployment to run 2 pods matching the template
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-lb
spec:
  type: LoadBalancer
  ports:
    - name: "http-port"
      protocol: "TCP"
      port: 80
      targetPort: 80 # Vserver groupのtarget
  selector:
    app: nginx # 上のNignxアプリを指定する必要がある

少し応用的なパターン。 コンテナのログの収集をLogServiceにさせるのと、Ingressも利用してみるパターン。L7レイヤーの制御が可能になる、
