错误:getaddrinfo ENOTFOUND ingress-nginx.ingress-nginx-controller.svc.cluster.local [英] Error: getaddrinfo ENOTFOUND ingress-nginx.ingress-nginx-controller.svc.cluster.local

问题描述

我正在使用 NextJS，我需要它知道它何时在服务器或浏览器上发出请求.要在服务器端执行此操作，因为我在微服务架构中构建它，我需要获取服务的服务名称和命名空间以完成 url，如 http://SERVICENAME.NAMESPACE.svc.cluster.local.

I am working with NextJS and I need for it to know when it's making a request on the server or on the browser. To do it on the server-side because I am building this inside a microservices architecture, I need to obtain the service name and namespace of the service to complete the url like so http://SERVICENAME.NAMESPACE.svc.cluster.local.

所以在我的终端中，我打印出了所有不同的命名空间，如下所示:

So in my terminal I printed out all my different namespaces like so:

$kubectl get namespace

NAME              STATUS   AGE
default           Active   9d
ingress-nginx     Active   9d
kube-node-lease   Active   9d
kube-public       Active   9d
kube-system       Active   9d

所以 ingress-nginx 就是我要找的.然后我跑了:

So ingress-nginx is what I am looking for. Then I ran:

$kubectl get services -n ingress-nginx

NAME                                 TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
ingress-nginx-controller             LoadBalancer   10.100.129.149   localhost     80:30463/TCP,443:31399/TCP   9d
ingress-nginx-controller-admission   ClusterIP      10.111.40.184    <none>        443/TCP                      9d

所以据我了解 ingress-nginx-controller 是我的服务的名称.

So to my understanding ingress-nginx-controller is the name of my service.

所以我向 http://ingress-nginx.ingress-nginx-controller.svc.cluster.local/api/users/currentuser 发出请求，但我还必须指定一个主机是这样的:

So I am making the request to http://ingress-nginx.ingress-nginx-controller.svc.cluster.local/api/users/currentuser, but I also had to specify a host like so:

LandingPage.getInitialProps = async () => {
  if (typeof window === "undefined") {
    const { data } = await axios.get(
      "http://ingress-nginx.ingress-nginx-controller.svc.cluster.local/api/users/currentuser",
      {
        headers: {
          Host: "ticketing.dev",
        },
      }
    );

    return data;
  } else {
    const { data } = await axios.get("/api/users/currentuser");

    return data;
  }
};

但是当我提出请求时，我仍然在浏览器上打印出来:

but when I make the request I am still getting this printing out on the browser:

我拉出了 kubectl 日志，一切都是 200:

I pulled kubectl logs and everything is 200:

我错过了什么?我认为问题不在 ingress-srv.yml 文件中:

What am I missing? I don't think the issue is in the ingress-srv.yml file:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  rules:
    - host: ticketing.dev
      http:
        paths:
          - path: /api/users/?(.*)
            backend:
              serviceName: auth-srv
              servicePort: 3000
          - path: /?(.*)
            backend:
              serviceName: client-srv
              servicePort: 3000

推荐答案

基于访问服务的URL:

Base on URL of accessing the service:

http://SERVICENAME.NAMESPACE.svc.cluster.local 

应该是这样的

http://ingress-nginx-controller.ingress-nginx.svc.cluster.local
