Install Jenkins Container

How to use this image

This will store the Jenkins data in /your/jenkins/home on your host. Ensure that /your/jenkins/home is accessible by the Jenkins container (jenkins user - uid 1000).

The first time, you must create /your/jenkins/home.

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

Once Jenkins is ready, the output will print a password which you'll need for later.

Backing up data

If you mount Jenkins as a Docker container, you can just back up Jenkins copying the /jenkins_home folder.

Restoring data

If you need to restore some previous Jenkins configuration, you just need to run this.

docker run -p 8080:8080 -p 50000:50000 -v /your/backup/jenkinshome/folder:/var/jenkins_home jenkins

Configure Admin user

You can access to Jenkins Portal using the specified port on your browser. The first time, you’ll need the secret key, you’ll find it in

/var/Jenkins_home/secrets/initialAdminPassword

With Jenkins unlocked, select the first option “Install suggested plugins”. This will install plugins that will use in the next steps.
Then, set your credentials and then we’re ready to go.

Update Jenkins

You need to remove your actual Jenkins container and Jenkins image. (Keep your /jenkins_home in the same directory, all jenkins configuration is located there).

Then you need to download the last Jenkins Image.

docker pull jenkins:latest

docker run --name jenkins_container -p 8080:8080 -p 50000:50000 -v /your/jenkins/home:/var/jenkins_home jenkins

Once complete you'll have your jenkins up to date.
