Question

我们无法从pod群集外部访问nginx。请帮助我们了解以下是否正确以及哪个端口将服务于nginx。在NodeIP上运行curl：NodePort抛出我们公司代理访问被拒绝的页面。我们在openstack上安装了VM，安全组已经开放。

[root@ip-10-0-0-3 pods]# kubectl get deployments NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE nginx-demo 2 2 2 2 4m

[root@ip-10-0-0-3 pods]# kubectl get pods NAME READY STATUS RESTARTS AGE nginx-demo-1947000120-6omcz 1/1 Running 0 5m nginx-demo-1947000120-exewa 1/1 Running 0 5m

以下是Kubernetes部署和服务文件。
