讓我們加密證書頒發

[英]Let's Encrypt Certificate Issuance

 原文  2020-04-07 19:16:43  4   2    ssl/ kubernetes/ ssl-certificate

問題描述

我正在嘗試獲得 Let's Encrypt 頒發的證書，已經 3 個半小時了。

我最初不小心將我的 secretName 設置為“echo-tls”，然后將其切換為我想要使用的正確“pandaist-tls”。

我目前有這個：

kubectl get CertificateRequest -o wide
NAME                      READY   ISSUER             STATUS                                                                                             AGE
pandaist-tls-1926992011   False   letsencrypt-prod   Waiting on certificate issuance from order default/pandaist-tls-1926992011-2163900139: "pending"   3h26m

當我描述證書時，我得到這個：

然后我查看我的 cert-manager pod 的日志——這里是每個的一小部分：

然后在這里，我仍然看到 echo-tls，盡管我將入口更改為使用 pandaist-tls：

我的入口：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: pandaist-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
spec:
  tls:
  - hosts:
    - pandaist.com
    - auth.pandaist.com
    secretName: pandaist-tls
  rules:
  - host: pandaist.com
    http:
      paths:
      - backend:
          serviceName: pandaist-main
          servicePort: 80
  - host: auth.pandaist.com
    http:
      paths:
      - backend:
          serviceName: pandaist-keycloak
          servicePort: 80

這個入口絕對是在回聲之后應用的。

這只是正常的證書批准時間（3.5 小時）還是意外包含 echo-tls 弄亂了我的證書頒發？ 如果是這樣，我該如何解決？

2 個解決方案

解決方案1
 2  2020-04-07 22:41:00

由於負載均衡器在 Digital Ocean 上的工作方式存在錯誤：

https://www.digitalocean.com/community/questions/how-do-i-correct-a-connection-timed-out-error-during-http-01-challenge-propagation-with-cert-manager

這將解決問題：

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  annotations: 
    # See https://github.com/digitalocean/digitalocean-cloud-controller-manager/blob/master/docs/controllers/services/examples/README.md#accessing-pods-over-a-managed-load-balancer-from-inside-the-cluster
    service.beta.kubernetes.io/do-loadbalancer-hostname: "kube.mydomain.com"
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  externalTrafficPolicy: Local
  type: LoadBalancer
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
  ports:
    - name: http
      port: 80
      targetPort: http
    - name: https
      port: 443
      targetPort: https

如果@Cecil 的解決方案不起作用，這可能值得一看。 我在Connection Timeout方面遇到了類似的問題

在ingress-nginx服務中更改LoadBalancer 。

添加/更改externalTrafficPolicy: Cluster 。

原因是，帶有證書頒發者的 pod 與負載均衡器在不同的節點上結束，因此它無法通過入口與自己對話。

以下是取自https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.26.1/deploy/static/provider/cloud-generic.yaml的完整塊

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  #CHANGE/ADD THIS
  externalTrafficPolicy: Cluster
  type: LoadBalancer
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
  ports:
    - name: http
      port: 80
      targetPort: http
    - name: https
      port: 443
      targetPort: https
