Kubernetescurl集群IP超时

Question

我是 K8 的新手。我已经部署了一个 nginx 服务，如下所示

kubectl describe svc nginx-nfs-service 

Name:              nginx-nfs-service
Namespace:         default
Labels:            <none>
Annotations:       <none>
Selector:          app=nginx
Type:              ClusterIP
IP Family Policy:  SingleStack
IP Families:       IPv4
IP:                10.105.179.135
IPs:               10.105.179.135
Port:              <unset>  80/TCP
TargetPort:        80/TCP
Endpoints:         172.16.222.234:80
Session Affinity:  None
Events:            <none>

这是运行该服务的 pod

kubectl describe pod nginx-nfs-deployment-5dd946cdd6-7hh4k

在控制平面节点上，我尝试做

curl https://10.105.179.135

但是超时了。我需要帮助来解决这个问题。我可以从控制平面 ping 托管该服务的节点。

Answer 1

至少我看到nginx pod使用端口80，但你想使用https（端口443）。除非您进行设置，否则不会自动重定向。

因此，如果您需要使用 https 和端口 443，您可以设置使用 TLS 证书的入口规则。
