如何绕过指定“主机"标头，以访问由Ingress控制器指向的服务? [英] How to get around specifying "Host" header to access services pointed by Ingress controllers?

问题描述

我的入口控制器正在运行，并且我可以使用http://(externalIP)/path使用来自RestClient的HTTP GET请求使用群集外的服务.但是，我必须为"Host"标头指定value = "host"(我的Ingress资源的值)才能正常工作.因此，我无法从Web浏览器中点击http://(externalIP)/path.有什么方法可以使我能够从外部Web浏览器进行访问而不必在请求标头中指定"Host"吗?

My ingress controller is working and I am able to access the service outside the cluster using http://(externalIP)/path using an HTTP GET request from a RestClient. However, I had to specify the "Host" header with value = "host" (value of my Ingress Resource) for this to work. Because of this, I am not able to hit http://(externalIP)/path from my web browser. Is there any way I can enable access from my external web browser without having to specify "Host" in the request header?

入口资源:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  namespace: ingress-nginx
  annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: master1.saas.com
    http:
      paths:
      - backend:
          serviceName: gen-devops
          servicePort: 10311
        path: /*

入口服务:

apiVersion: v1
kind: Service
metadata:
  name: ingress-nginx
 namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  type: NodePort
  ports:
    - name: http
      port: 80
      targetPort: 80
      protocol: TCP
    - name: https
      port: 443
      targetPort: 443
      protocol: TCP
   externalIPs:
    - 172.16.32.85

  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx

推荐答案

我假设您要使用它进行测试.

I assume you want to use this for testing.

如果您正在使用任何* nix风味操作系统(MacOS，Linux)，则可以将条目添加到/etc/hosts文件中，如下所示:

If you are using any *nix flavor OS (MacOS, Linux) you can add an entry to your /etc/hosts file, something like this:

172.16.32.85 master1.saas.com

如果使用任何Windows框，都可以在C:\Windows\System32\Drivers\etc\hosts

If you are using any Windows box you can add the same entry in C:\Windows\System32\Drivers\etc\hosts
