在Docker中创建Jenkins的卷备份[Linux] [英] Create volume backup of Jenkins in Docker [Linux]

问题描述

我在Docker中安装了Jenkins，我需要创建备份并在需要时还原它们. 我尝试了一些插件，但是因为我使用的是docker，所以它们无法工作.除此之外，我还需要备份所有内容，包括历史数据.

I have a Jenkins installation in Docker and I need to create backups and restore them when I need. I tried some plugins but because I'm using docker they don't work. Besides that, I need to backup everything including historic.

我偶然发现了此页面:

I stumbled on this page: https://medium.com/pacroy/how-to-backup-and-restore-your-jenkins-data-volume-in-docker-2ac66d99315a

但是说明是针对Windows的，我无法使其适应我的linux环境.

but the instructions are for windows and I can't adapt that to my linux environment.

我的问题是:如何在docker中创建我的jenkins实例的完整备份，以使其可以还原甚至在另一台机器上创建副本.

My question is: how can I create full backups of my jenkins instance in docker in a way that I can restore it or even create a copy in another machine.

谢谢.

推荐答案

所有Jenkins数据(包括作业配置和内部版本)都存储在容器内的/var/jenkins_home下.

All the Jenkins data including job configuration and builds are stored under /var/jenkins_home inside the container.

因此，您可以简单地备份此文件夹，所有Jenkins状态将保持不变.您可以使用以下方法定期从容器中复制此文件夹:

Thus you can simply backup this folder and all the Jenkins state will be persisted. You can regularly copy this folder from the container using:

docker cp <jenkins-container-name>:/var/jenkins_home ./jenkins_home

从这些备份中的任何一个中，您都可以使用以下命令启动新的jenkins实例:

You from anyone of these backup you can start a new jenkins instance using the command:

docker run -v ./jenkins_volume:/var/jenkins_home -p 8080:8080 jenkins ...
