General

Hi , Am running jenkins through docker, if i stop the container then am loosing all the data. Again if i start it is loading from beginning,whats the backup strategy for this.

Quick reply is highly appreciated.

Take a look at the docs for the Jenkins image, the second example

docker run -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins:lts

already shows how to create a volume with persistent data.

Hey tekki, i have started with this command only. my query is that when i want to stop that container all the data will be lost,but if i want to retrieve that data then what shall i do. how do i restart the container with old data

The data from /var/jenkins_home is saved in the volume jenkins_home, if you attach it to the new container it will be here again.

Hi Tekki,

Thanks for the answer, but if i type docker volume ls command then i am unable to find this volume(jenkins_home) where to check exactly

Try it like this:

$ docker run -d -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins:lts
