主要更新后的证书管理器停止工作

Question

这个问题是在 cert-manager 从 0.6.0 版本重大更新到 0.11.0 版本后出现的。更新已通过配置备份、cert-manager 删除、helm 更新、cert-manager 安装和备份恢复进行处理。更新期间没有配置更改。

Pod 和服务已启动，但更新后未颁发证书。

有证书管理器服务的日志：

我的 ClusterIssuer yaml：

apiVersion: certmanager.k8s.io/v1alpha2
kind: ClusterIssuer

    privateKeySecretRef:

Answer 1

apiVersion 已从 certmanager.k8s.io/v1alpha1 更改为 cert-manager.io/v1alpha2。但是您仍然有 CRD 和旧的 apiVersion，您需要将其删除。

按照以下步骤升级证书管理器注意第 3 步和第 4 步。

1.Back 根据 backup and restore guide.

现有的证书管理器资源

2.Uninstall cert-manager

3.Ensure旧的cert-manager CRD资源也被删除了：kubectl get crd | grep certmanager.k8s.io

4.Update 从 certmanager.k8s.io/v1alpha1 到 cert-manager.io/v1alpha2.

所有备份资源的 apiVersion

5.Re-根据installation guide

从头开始安装cert-manager

这里是官方upgrade guide

Answer 2

感谢回复。我在 helm purge cert-manager 之后删除了旧的 CRD，并使用清单安装了新版本 0.12。我当前的 CRD 如下：

kubectl get crd 
NAME                                    CREATED AT
certificaterequests.cert-manager.io     2019-11-01T01:37:03Z

并更新了 ClusterIssuer 的描述

kubectl describe ClusterIssuer letsencrypt-prod
Name:         letsencrypt-prod
Namespace:
Labels:       <none>
Annotations:  <none>
API Version:  cert-manager.io/v1alpha2
Kind:         ClusterIssuer

  Resource Version:    71299934
  Self Link:           /apis/cert-manager.io/v1alpha2/clusterissuers/letsencrypt-prod
  UID:                 4465c9ce-3759-11ea-be9c-0a7022c023e8

      Selector:

我在 cert-manager 命名空间下没有入口。此外，我的备份包括旧证书、CRD、颁发者、证书和证书请求等，但我不知道如何恢复所需的内容。

Answer 3

已排序。罪魁祸首是 1) 证书管理器安装不完整。 2) 我还修改了备份并将所有 certmanager.k8s.io 替换为 cert-manager.io 并将 v1alpha1 替换为 v1alpha2。 3) 手动删除其他与certmanager.k8s.io CRDs
