Question

我最近在Jenkins服务器上遇到磁盘限制。我决定通过安装更大的卷来永久解决此问题，并将Jenkins主目录移动到该卷。我将此维基页面用作此迁移的参考：https://wiki.jenkins.io/display/JENKINS/Administering+Jenkins。我正在使用init.d启动Jenkins，并更改了/ etc / default / jenkins中的JENKINS_HOME目录（init脚本引用此位置来获取其默认值）。

重新启动Jenkins之后，我可以确认它在新的Home目录中正在运行。我的构建最初有效（scm签出-> docker构建-> test->推送到docker注册表）。但是，当到达推送阶段时，将生成一个错误，指出无法创建目录/ var / lib / jenkins。这是旧的JENKINS_HOME（因为新的JENKINS_HOME设置在/ mnt / jenkins）。完整的堆栈跟踪可以在下面看到。

我在这里想念什么？移动中是否还有其他相关设置？我正在使用docker-commons和docker-pipeline插件。我们非常感谢您的帮助。

Answer 1

TLDR；解决方案：将所有凭证文件和目录移回原始位置，或更改jenkins用户的主目录[usermod -d /new/dir jenkins]（这是我所做的）。请确保先移开文件，因为usermod命令无法在现有目录上运行。

经过一番摆弄之后，我发现了问题。也许这对其他人有帮助。

jenkins用户的主目录仍位于/ var / lib / jenkins。这是存储dockerhub凭据的目录。在工作期间，Jenkins尝试访问旧位置上的凭据，因为默认情况下，它在jenkins用户主目录中查找。

Jenkins Docker管道插件引用了旧的JENKINS_HOME
