未找到 Cert-manager 证书且未创建挑战

Question

我从头到尾都关注https://docs.cert-manager.io/en/venafi/tutorials/quick-start/index.html，一切似乎都在工作，只是我没有为我的入口获取外部 IP。

NAME                     HOSTS                                  ADDRESS   PORTS     AGE
staging-site-ingress   staging.site.io,staging.admin.site.io,             80, 443   1h

尽管我能够使用 nginx 入口控制器外部 ip 并使用 dns 访问站点。当我访问 url 时，我被重定向到 https，所以我认为它工作正常。

它重定向到 https，但仍然显示“不安全”，因此他没有获得颁发的证书。

当我调试时，我得到以下信息：

入口：

证书：

秘密：

Name:         letsencrypt-staging-tls
Namespace:    staging
Labels:       certmanager.k8s.io/certificate-name=staging-site-io
Annotations:  <none>

Type:  kubernetes.io/tls

Data
====
ca.crt:   0 bytes
tls.crt:  0 bytes
tls.key:  1679 bytes

订单：

Status:
  Certificate:   <nil>
  Finalize URL:  
  Reason:        
  State:         
  URL:           
Events:          <none>

因此，似乎顺序出现了问题，并且没有产生任何挑战。

这是我的 ingress.yaml 和 issuer.yaml：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: staging-site-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"    
    certmanager.k8s.io/issuer: "letsencrypt-staging"
    certmanager.k8s.io/acme-challenge-type: http01
spec:
  tls:
  - hosts:
    - staging.site.io
    - staging.admin.site.io
    - staging.api.site.io
    secretName: letsencrypt-staging-tls
  rules:
    - host: staging.site.io
      http:
        paths:
          - backend:
              serviceName: frontend-service
              servicePort: 80
            path: /
    - host: staging.admin.site.io
      http:
        paths:

            path: /
    - host: staging.api.site.io
      http:
        paths:

              serviceName: gateway-service
              servicePort: 9000
            path: /

apiVersion: certmanager.k8s.io/v1alpha1
kind: Issuer
metadata:
  name: letsencrypt-staging
  namespace: staging
spec:
  acme:

    email: hello@site.io
    privateKeySecretRef:
      name: letsencrypt-staging-tls
    http01: {}

任何人都知道我可以做些什么来解决这个问题或出了什么问题？ Certmanager 安装正确 100%，我只是不确定入口以及顺序出了什么问题。

提前致谢！

编辑：我在 nginx-ingress-controller 中找到了这个：

W0227 14:51:02.740081       8 controller.go:1078] Error getting SSL certificate "staging/letsencrypt-staging-tls": local SSL certificate staging/letsencrypt-staging-tls was not found. Using default certificate

垃圾邮件越来越多，CPU 负载始终为 0.003，cpu 图已满（其他服务几乎没有）

Answer 1

按照完全相同的官方教程，我偶然发现了同样的问题。 正如@mikebridge 提到的，问题在于Isser/Secret 的命名空间不匹配。

对我来说，最好的办法是从 Issuer 切换到 ClusterIssuer，它不限于单个命名空间。
