等待 http-01 质询传播：未能执行自我超时

Question

我设置了一个 kubernetes 集群，当前有两个节点，metallb 作为负载均衡器。

目前我想使用 Ingress 并通过 ssl 保护它。为此，我决定将 nginx ingress 与 cert-manager 结合使用，并在教程结束后将其放在他们的网站上。

但现在我收到错误“等待http-01挑战传播：无法执行自检GET请求' http://example.....zone/.well-known/acme-challenge/A5lFUj69fDccpXlvlyVw9-ekATEjt_-DKiJUzJSafxs ' ：获取“ http://example.....zone/.well-known/acme-challenge/A5lFUj69fDccpXlvlyVw9-ekATEjt_-DKiJUzJSafxs ”：拨打tcp 94.130.150.125:80：连接：连接超时“

我当前的 ClusterIssuer 如下所示：

apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
 name: letsencrypt-prod
 namespace: cert-manager
spec:
 acme:
   # The ACME server URL
   server: https://acme-v02.api.letsencrypt.org/directory
   # Email address used for ACME registration
   email: letsencrypt@mymail.de
   # Name of a secret used to store the ACME account private key
   privateKeySecretRef:
     name: letsencrypt-prod
   # Enable the HTTP-01 challenge provider
   solvers:
   - http01:
       ingress:
         class:  nginx

我正在尝试自动提供证书

---
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
    cert-manager.io/acme-challenge-type: http01
spec:
  tls:
  - hosts:
    - example.....zone
    secretName: example-...-zone-tls
  rules:
  - host: example.....zone
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx-service
          servicePort: 80

手动我可以完美到达任何地址。

这对我有用。

LoadBalancer服务变化ingress-nginx。

添加/更改externalTrafficPolicy: Cluster。

原因是，具有证书颁发者的 Pod 与负载均衡器位于不同的节点上，因此它无法通过入口与自身通信。
