這樣創(chuàng)建了headless service:

myapp-service-headless.yaml

apiVersion: v1
kind: Service
metadata:
  name: myapp-service-headless
spec:
  ports:
    - port: 8000
  selector:
    app: myapp
  clusterIP: None

創(chuàng)建到Kubernets集群并查看狀態(tài)：

$ kubectl create -f myapp-service-headless.yaml
$ kubectl describe service myapp-service-headless
Name:              myapp-service-headless
Namespace:         default
Labels:            <none>
Annotations:       <none>
Selector:          app=myapp
Type:              ClusterIP
IP:                None
Port:              <unset>  8000/TCP
TargetPort:        8000/TCP
Endpoints:         172.17.0.11:8000,172.17.0.9:8000
Session Affinity:  None
Events:            <none>

現(xiàn)在連接172.17.0.11:8000或172.17.0.9:8000,停止沒有結(jié)果。

在部署到Pods中容器的應用程序里使用了kube-dns: myapp-service-headless.default.svc.cluster.local。

這種情況如何通過API連接到里面的應用程序？哪個IP可用？有人說用Ingress controller從Nginx中設置，是正確方法嗎？
