kubernets之service測試

部署nginx service做測試。
部署nginx:
kubectl run nginx --image=nginx --replicas=2 --labels="run=load-nginx-example" --port=80 ##端口一定是80要不然訪問不成功，提示拒絕連接

查看信息：kubectl get pods --all-namespaces -o wide |grep nginx

定義service:
kubectl expose deployment nginx --type=NodePort --name=test-service

kubectl describe svc test-service
