Error: stat /mnt/jenkins-store: no such file or directory

Question

非常困惑，我使用一个ec2实例来引导一个星期的集群，昨天一切都工作得很好。我昨晚删除了那个集群，刚刚启动了一个新的集群，现在我在试图构建我的jenkins pod时遇到了这个错误

Error: stat /mnt/jenkins-store: no such file or directory

我觉得很奇怪，为什么这个错误昨天没有显示，我今天设置的一切完全相同的方式。这个错误是我在描述我的jenkins pod时得到的。

这是我的jenkins。参考的Yaml文件

Answer 1

与此答案类似，检查作为新生成的ec2实例启动的ec2-run-instances是否应该不包含一些卷，这些卷随后将被jenkins.yaml使用。

缺少这样一个卷可以解释Error: stat /mnt/jenkins-store消息。
