ArgoCD与nginx入口和证书管理器不工作

Question

我尝试在GKE集群(版本1.21.5-gke.1302)中使用ingress和cert-manager来公开ArgoCD，但是证书没有颁发。

重现步骤：

>

安装证书管理器应用此 yaml

在运行helm的情况下安装ngin x入口控制器：helm安装my-发布ngin x-稳定/ngin x-入口

应用以下内容创建集群颁发者：

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-cluster-issuer
spec:
  acme:
    email: [e-mail]
    server: https://acme-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      name: letsencrypt-cluster-issuer-key
    solvers:
    - http01:
       ingress:
         class: nginx

• 使用本指南和文件应用入口：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: argocd-server-ingress
  namespace: argocd
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
    kubernetes.io/ingress.class: nginx
    kubernetes.io/tls-acme: "true"
    nginx.ingress.kubernetes.io/ssl-passthrough: "true"
    # If you encounter a redirect loop or are getting a 307 response code 
    # then you need to force the nginx ingress to connect to the backend using HTTPS.
    #
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
spec:
  rules:
  - host: argocd.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service: 
            name: argocd-server
            port:
              name: https
  tls:
  - hosts:
    - argocd.example.com
    secretName: argocd-secret # do not change, this is provided by Argo CD

< li >将入口控制器的ip映射到您的主机名。

预期行为:我期望证书被成功创建并可以访问应用程序。

当前状态：

证书描述给了我这个：

最后，我可以通过质询访问提供的url，但状态待定，原因如下：等待HTTP-01质询传播：未能执行自检GET请求

有人知道可能出了什么问题吗？非常感谢。

谢谢！

Answer 1

我认为你需要具体说明:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-cluster-issuer
spec:
  acme:
    email: [e-mail]
    server: https://acme-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      name: argocd-secret # HERE use secrets created by ArgoCD
    solvers:
    - http01:
       ingress:
         class: nginx

Answer 2

看起来您在ArgoCD的入口规则中有一个不同的群集问题名称。在ClusterIssuer清单中的示例中：

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-cluster-issuer

并从入口规则

  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
