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:
              serviceName: nginx
              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

返回

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

我执行

kubectl cluster-info

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出问题所在

Answer 1

您为入口控制器提供了一个与请求的 host 标头相匹配的规则，但是由于某种奇怪的原因，您正在测试的请求不提供主机标头。

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

curl：（7）无法连接到xx.xx.xx.xx：80;拒绝连接
