Question

我想在Docker上使用Jenkins设置CI / CD平台，我有一个Dockerfile，该文件通过插件，作业，管道，用户等来设置Jenkins。但是，在启动Jenkins时，我进行了全新安装，并且所有设置都被覆盖。我想念某个地方的标志吗？

  FROM jenkins/jenkins:lts

您只需要在运行容器时使用卷：

例如，下面的示例实例化一个名为 jenkins 的容器，并使用 / var / jenkins_home 在主机中安装路径 / my_server / jenkins_home strong>容器内：

docker run -t --name jenkins -p 8080:8080 -v /my_server/jenkins_home:/var/jenkins_home jenkins

因此，当您启动或停止容器时，主机服务器中的该文件夹将完整保留 / my_server / jenkins_home 并将用于您的容器。 Jenkins中的所有配置都可以使用。

对我有用的解决方法是将-Djenkins.install.runSetupWizard附加到jenkins选项。请参阅下面的我的dockerfile：
