【问题描述】：
我在 kubernetes 上运行 Jenkins。在最后一次重新创建 pod 后，它无法正常工作。这是我的日志的样子：

一旦我描述了 pod，我可以看到运行状况检查失败

Pod 状态如下所示：
jenkins-694d964d7-w9xnp 0/1 Running:0/1 0 8m
知道如何解决这个问题吗？我不是 Jenkins/kubernetes 专家，我继承了这个配置。提前感谢您的帮助！
【问题讨论】：
-
成功了吗？你是如何在 kubernetes 上安装 jenkins 的？给出 pod 列表。您是否尝试过检查 scm-api 插件的错误？ jenkins 版本有什么变化吗？
-
@Vitalii 它一直工作到昨天。 Jenkins 是使用 helms 安装的。我可以看到 pod 没有正确创建
jenkins-694d964d7-w9xnp 0/1 Running:0/1 0 8m我还在描述中添加了 pod 的事件部分
