在上一篇中我們已經把服務部署完成，接下來我們要進一步來設定對外IP。

Service的類型LoadBalancer

建立地區静態IP

建立完成後，在loadBalancerIP帶入靜態IPYOUR-IP

# service_hs_exter.yaml
apiVersion: v1
kind: Service
metadata:
  name: hs-exter
  namespace: dev-ithome
spec:
  type: LoadBalancer
  loadBalancerIP: "YOUR-IP" 
  ports:
  - name: http
    port: 8080
    targetPort: 8080
    protocol: TCP
  selector:
    app: hs

kubectl -n dev-ithome get svc
NAME       TYPE           CLUSTER-IP    EXTERNAL-IP      PORT(S)        AGE
gs         ClusterIP      10.229.4.49   <none>           8081/TCP       15m
hs-exter   LoadBalancer   10.229.2.25   x.x.x.x          80:32754/TCP   2m13s

完成後就可以，透過外網IP連到服務

Ingress

使用Ingress静態IP，需要先建立二個資源：

1. 類型為 type: NodePort或LoadBalancer的Service
2. 需要先全域静態IP

執行下列指令，建立全域静態IP

gcloud compute addresses create test-static-ip --global

查看建立的IP

gcloud compute addresses describe test-static-ip --global

# service_ingress_hs.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: hs-ingress
  namespace: dev-ithome  
  annotations:
    kubernetes.io/ingress.global-static-ip-name: test-static-ip
spec:
  rules:
  - host: xxx.xxx.xxx
    http:
      paths:
      - backend:
          serviceName: hs-backend
          servicePort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: hs-backend
  namespace: dev-ithome
spec:
  type: NodePort
  ports:
  - name: http
    port: 80
    targetPort: 8080
    protocol: TCP 
  selector:
