主要更新后的证书管理器停止工作

Question

该问题是在 cert-manager 从 0.6.0 到 0.11.0 版本的重大更新后开始的。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，但更新后没有颁发证书。

有 cert-manager 服务的日志：

我的 ClusterIssuer yaml：

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

Answer 1

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

按照以下步骤升级证书管理器，注意步骤 3 和 4。

1.按照备份和恢复指南备份现有的证书管理器资源。

2.卸载cert-manager

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

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

5.按照安装指南重新安装cert-manager

这是官方升级指南
