Ingress 和证书管理器未创建证书

Question

我正尝试按照这些指南在 Kubernetes 中部署入口路由：

• https://cert-manager.io/docs/tutorials/acme/ingress/
• https://docs.microsoft.com/en-us/azure/aks/ingress-static-ip

我已经部署了一个集群发行者：

apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
  name: letsencrypt
spec:
  acme:
    server: https://acme-v02.api.letsencrypt.org/directory
    email: <Myemail>
    privateKeySecretRef:
      name: letsencrypt
    solvers:
    - http01:
        ingress:
          class: nginx
          podTemplate:
            spec:
              nodeSelector:
                "kubernetes.io/os": linux

然后我部署了入口：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: airflow-ingress
  namespace: airflow6
  annotations:
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: letsencryp
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  tls:
  - hosts:
    - <MYhost>
    secretName: tls-secret1
  rules:
    - host: <MYhost>
      http:
        paths:
          - path: /
            backend:
              serviceName: airflow-web
              servicePort: 8080

然后如果我尝试获取证书：

kubectl describe certificate tls-secret1 --namespace airflow6

Error from server (NotFound): certificates.cert-manager.io "tls-secret1" not found

我已尝试部署我自己的证书：

apiVersion: cert-manager.io/v1alpha2
kind: Certificate
metadata:
  name: tls-secret1
  namespace: airflow6
spec:
  secretName: tls-secret1
  dnsNames:
  - <MYhost>
  issuerRef:
    name: letsencrypt
    # We can reference ClusterIssuers by changing the kind here.
    # The default value is Issuer (i.e. a locally namespaced Issuer)
    kind: ClusterIssuer
    group: cert-manager.io

然后运行相同的命令：

kubectl describe certificate tls-secret1 --namespace airflow6

  Normal  Requested  <invalid>                 cert-manager  Created new CertificateRequest resource "quickstart-example-tls-5gg9l"

我不知道是否需要创建这样的秘密：

 apiVersion: v1
  kind: Secret
    name: example-tls
    namespace: foo
  data:
    tls.crt: <base64 encoded cert>
    tls.key: <base64 encoded key>
  type: kubernetes.io/tls

但我真的不知道我必须在 tls.crt 和 tls.key 中输入什么。

在我阅读的所有指南中，我看到当自动部署入口路由时会创建一个证书，但对我来说不起作用，我哪里出错了？

Answer 1

不，你不应该自己创建 TLS 秘密，这就像你将秘密名称放在入口规则的 tls 部分，然后在进行 DNS 验证时，秘密将由发行者自己创建创建入口规则的相应命名空间。

要cross-check创建配置或创建新配置，您可以参考this
