我最近在 Jenkins 服务器上遇到了磁盘限制。我决定通过安装更大的卷并将 Jenkins 主目录移动到该卷来永久解决这个问题。我将此 wiki 页面用作移动的参考：https ://wiki.jenkins.io/display/JENKINS/Administering+Jenkins 。我正在使用 init.d 启动 Jenkins 并更改 /etc/default/jenkins 中的 JENKINS_HOME 目录（初始化脚本引用此位置以获取其默认值）。

重新启动 Jenkins 后，我可以确认它正在新的主目录中运行。我的构建最初可以工作（scm checkout->docker build->test->push to docker registry）。但是，当到达推送阶段时，会生成一个错误，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）。完整的堆栈跟踪如下所示。

我在这里错过了什么？移动中是否有其他相关设置？我正在使用 docker-commons 和 docker-pipeline 插件。非常感谢任何帮助。

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 用户主目录 [ usermod -d /new/dir jenkins]（这是我所做的）。确保首先将文件移开，因为 usermod 命令无法在现有目录上运行。

经过一番折腾，我发现了问题所在。也许这对其他人有帮助。

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