curl: (7) 连接到 xx.xx.xx.xx:80 失败;连接被拒绝

Question

我正在尝试部署nginx - 入口

kubectl run nginx --image=nginx
kubectl get pod 
NAME                                       READY     STATUS        RESTARTS   AGE
nginx-65899c769f-wf7dl                     1/1       Running       0          9m

kubectl expose deploy nginx --port 80
NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
nginx        ClusterIP   10.254.75.184      <none>     80/TCP           9m

vi ingress.yml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: nginx
spec:
rules:
- host: kub-mst.coral.io
http:
paths:
- backend:

servicePort: 80

kubectl get ing
NAME      HOSTS              ADDRESS   PORTS     AGE
nginx     kub-mst                      80        9m

---

vi /etc/hosts
xx.xx.xx.xx  kub-mst.coral.io

---

curl kub-mst.coral.io
curl: (7) Failed connect to kub-mst; Connection refused

我有 Kubernetes 集群，正在尝试

curl http://xx.xx.xx.xx

它返回

curl: (7) Failed connect to xx.xx.xx.xx:80; Connection refused

我执行

kubectl cluster-info

它返回

Kubernetes master is running at http://localhost:8080
KubeDNS is running at http://localhost:8080/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

xx.xx.xx.xx是公共IP。

如何进行故障排除以检测问题所在

Answer 1

您为入口控制器提供了与请求的主机标头匹配的单个规则，但是，出于某种奇怪的原因，您正在使用未提供主机标头的请求进行测试。

curl -H 'Host: kub-mst.coral.io' http://xx.xx.xx.xx
