主要更新停止工作后的证书管理器

Question

该问题是在 cert-manager 从 0.6.0 到 0.11.0 版本的重大更新之后开始的。 更新已通过配置备份、cert-manager remove、helm update、cert-manager install 和 backup restore 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。

cert-manager 服务有日志：

我的 ClusterIssuer yaml：

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

Answer 1

apiVersion 已从 certmanager.k8s.io/v1alpha1 更改为 cert-manager.io/v1alpha2。但是您仍然有需要删除的旧 apiVersion 的 CRD。

按照以下步骤升级证书管理器注意 第 3 步和第 4 步。

1.按照backup and restore guide备份现有的cert-manager资源。

2.Uninstall cert-manager

3.确保旧的 cert-manager CRD 资源也已被删除：kubectl get crd | grep certmanager.k8s.io

4.将所有备份资源上的 apiVersion 从 certmanager.k8s.io/v1alpha1 更新为 cert-manager.io/v1alpha2。

5.根据installation guide重新安装cert-manager

这里是官方upgrade guide

Answer 2

已排序。罪魁祸首是 1）不完整的 cert-manager 安装。 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相关的CRDs

Answer 3

感谢您的回复。 我在 helm purge cert-manager 之后删除了旧的 CRD，并使用清单安装了新的 0.12 版本。 下面是我当前的 CRD：

kubectl get crd 
NAME                                    CREATED AT

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

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

    Solvers:

      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。
