【问题描述】：
我正在关注这个文档https://kubernetes.io/docs/concepts/services-networking/connect-applications-service/
但我希望能够 curl 一些 localhost:8080 或类似的东西。
主机期望的确切 curl 命令和端口是什么。不在集群上，不在节点上，而是从主机上。
我在 microk8s 中运行。
这是我申请的文件，从文档中复制：
apiVersion: v1

spec:

- port: 8080

- containerPort: 80
volumeMounts:

- mountPath: /etc/nginx/conf.d

这是k get deployment my-nginx -o yaml 命令的输出：

文档中也有这个 default.conf
cat default.conf
server {

listen [::]:80 default_server ipv6only=on;
listen 443 ssl;

}
}
【问题讨论】：
-
你能告诉我们
kubectl get deployment < deployment-name> -o yaml的输出吗？ -
加你试过的yaml更好？

@H.R.Emon 我已经更新了详细信息。这就是为什么我经常抱怨这类文档......他们应该总是只有一个带有 README.md 的 make 文件所有这些复制意大利面都没有意义，因为它并没有真正的帮助你学。当您尝试自己的项目时，您就会学习。
