我在使用 cert-manager 处理 tls 证书时遇到了问题，我正在关注文档并添加了一些额外的东西Traefik作为入口。

目前，我有这些YAML文件：

集群发行者.yaml

apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
  name: letsencrypt-staging
  namespace: secure-alexguedescom
spec:
  acme:
    email: user@gmail.com
    server: https://acme-staging-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      # Secret resource used to store the account's private key.
      name: letsencrypt-staging
    # Add a single challenge solver, HTTP01 using nginx
    solvers:
      - selector: {}
        http01:
          ingress:
            class: traefik-cert-manager

traefik-ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    # add an annotation indicating the issuer to use.
    cert-manager.io/cluster-issuer: letsencrypt-staging
  name: secure-alexguedescom-ingress-http
  namespace: secure-alexguedescom
spec:
  rules:
  - host: secure.alexguedes.com
    http:
      paths:
      - backend:
          serviceName: secure-alexguedescom-nginx
          servicePort: 80
        path: /
  tls: 
  - hosts:
    - secure.alexguedes.com
    secretName: secure-alexguedescom-cert

cert-staging.yaml

apiVersion: cert-manager.io/v1alpha2
kind: Certificate
metadata:
  name: secure-alexguedescom-cert
  namespace: secure-alexguedescom
spec:
  commonName: secure.alexguedes.com
  secretName: letsencrypt-staging
  dnsNames:
    - secure.alexguedes.com
  issuerRef:
    name: letsencrypt-staging
    kind: ClusterIssuer

检查证书我有这个错误消息：

Message: Issuing certificate as Secret does not contain a certificate
Reason: MissingData

还检查了certificaterequest我有这个日志消息：

Status:
  Conditions:
    Last Transition Time:  2020-08-16T00:32:01Z
    Message:               Waiting on certificate issuance from order secure-alexguedescom/secure-alexguedescom-cert-q8w5p-1982372682: "pending"
    Reason:                Pending
    Status:                False
    Type:                  Ready

  Normal  OrderPending  11m   cert-manager  Waiting on certificate issuance from order secure-alexguedescom/secure-alexguedescom-cert-q8w5p-1982372682: ""

我不确定哪一块是错的，使用 Helm v2 和 Tiller 和 k8s v1.7

有任何想法吗？

提前致谢

letsencrypt证书的典型问题是letsencrypt 本身无法验证您是谁以及您拥有该域。在这种情况下，alexguedes.com。

使用 cert-manager 您可以进行Domain Validation和HTTP Validation。根据发布的ClusterIssuer内容，您正在进行 HTTP 验证。因此，您需要确保secure.alexguedes.com解析为全局可用的 IP 地址，并且 Traefik 端口443正在侦听该 IP 地址。
