 This will store the workspace in /var/jenkins_home. All Jenkins data lives in there - including plugins and configuration. You will probably want to make that a persistent volume (recommended):
 
 ```
-docker run --name myjenkins -p 8080:8080 -v /var/jenkins_home jenkins
+docker run --name myjenkins -p 8080:8080 -v /your/home:/var/jenkins_home jenkins
 ```
 
 The volume for the "myjenkins" named container will then be persistent.
