[jenkins] Export/import jobs in Jenkins

Is it possible to exchange jobs between 2 different Jenkins'? I'm searching for a way to export/import jobs.

As a web user, you can export by going to Job Config History, then exporting XML.

I'm in the situation of not having access to the machine Jenkins is running on and wanted to export as a backup.

As for importing the xml as a web user, I'd still like to know.

This does not work for existing jobs, however there is Jenkins job builder.

This allows one to keep job definitions in yaml files and in a git repo which is very portable.

Thanks to Larry Cai's answer I managed to create a script to backup all my Jenkins jobs. I created a job that runs this every week. In case someone finds it useful, here it is:

#!/bin/bash
#IFS for jobs with spaces.
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
for i in $(java -jar /run/jenkins/war/WEB-INF/jenkins-cli.jar -s http://server:8080/ list-jobs); 
do 
  java -jar /run/jenkins/war/WEB-INF/jenkins-cli.jar -s http://server:8080/ get-job ${i} > ${i}.xml;
done
IFS=$SAVEIFS
mkdir deploy
tar cvfj "jenkins-jobs.tar.bz2" ./*.xml

If you have exported the config.xml then use the same to import:

curl -k -X POST 'https:///<user>:<token>@<jenkins_url>/createItem?name=<job_name>' --header "Content-Type: application/xml" -d @config.xml

I am connecting via HTTPS and disabled certificate validation using -k.

• This is how to generate user api token on Jenkins.
• Jenkins REST API details can be seen if you click the link with same name at bottom right corner of your Jenkins instance.

In a web browser visit:

http://[jenkinshost]/job/[jobname]/config.xml

Just save the file to your disk.

Importing Jobs Manually: Alternate way

Upload the Jobs on to Git (Version Control) Basically upload config.xml of the Job.

If Linux Servers:

cd /var/lib/jenkins/jobs/<Job name> 
Download the config.xml from Git

Restart the Jenkins

The most easy way, with direct access to the machine is to copy the job folder from first jenkins to another one (you can exclude workspaces - workspace folder), because the whole job configuration is stored in the xml file on the disk.

Then in the new jenkins just reload configuration in the global settings (admin access is required) should be enough, if not, then you will need to restart Jenkins tool.

Another way can be to use plugins mentioned above this post.

edit: - in case you can probably also exclude modules folders

A one-liner:

$ curl -s http://OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST 'http://NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-

With authentication:

$ curl -s http:///<USER>:<API_TOKEN>@OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST 'http:///<USER>:<API_TOKEN>@NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-

With Crumb, if CSRF is active (see details here):

Get crumb with:

$ CRUMB_OLD=$(curl -s 'http://<USER>:<API_TOKEN>@OLD_JENKINS/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')
$ CRUMB_NEW=$(curl -s 'http://<USER>:<API_TOKEN>@NEW_JENKINS/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')

Apply crumb with -H CRUMB:

$ curl -s -H $CRUMB_OLD http:///<USER>:<API_TOKEN>@OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST -H $CRUMB_NEW 'http:///<USER>:<API_TOKEN>@NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-

For those of us in the Windows world who may or may not have Bash available, here's my PowerShell port of Katu and Larry Cai's approach. Hope it helps someone.

##### Config vars #####
$serverUri = 'http://localhost:8080/' # URI of your Jenkins server
$jenkinsCli = 'C:\Program Files (x86)\Jenkins\war\WEB-INF\jenkins-cli.jar' # Path to jenkins-cli.jar on your machine
$destFolder = 'C:\Jenkins Backup\' # Output folder (will be created if it doesn't exist)
$destFile = 'jenkins-jobs.zip' # Output filename (will be overwritten if it exists)
########################

$work = Join-Path ([System.IO.Path]::GetTempPath()) ([System.IO.Path]::GetRandomFileName())
New-Item -ItemType Directory -Force -Path $work | Out-Null # Suppress output noise
echo "Created a temp working folder: $work"

$jobs = (java -jar $jenkinsCli -s $serverUri list-jobs)
echo "Found $($jobs.Length) existing jobs: [$jobs]"

foreach ($j in $jobs)
{
    $outfile = Join-Path $work "$j.xml"
    java -jar $jenkinsCli -s $serverUri get-job $j | Out-File $outfile
}
echo "Saved $($jobs.Length) jobs to temp XML files"

New-Item -ItemType Directory -Force -Path $destFolder | Out-Null # Suppress output noise
echo "Found (or created) $destFolder folder"

$destPath = Join-Path $destFolder $destFile
Get-ChildItem $work -Filter *.xml | 
    Write-Zip -Level 9 -OutputPath $destPath -FlattenPaths |
    Out-Null # Suppress output noise
echo "Copied $($jobs.Length) jobs to $destPath"

Remove-Item $work -Recurse -Force
echo "Removed temp working folder"

Job Import plugin is the easy way here to import jobs from another Jenkins instance. Just need to provide the URL of the source Jenkins instance. The Remote Jenkins URL can take any of the following types of URLs:

• http://$JENKINS - get all jobs on remote instance

• http://$JENKINS/job/$JOBNAME - get a single job

• http://$JENKINS/view/$VIEWNAME - get all jobs in a particular view

Probably use jenkins command line is another option, see https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+CLI

• create-job: Creates a new job by reading stdin as a configuration XML file.
• get-job: Dumps the job definition XML to stdout

So you can do

java -jar jenkins-cli.jar -s http://server get-job myjob > myjob.xml
java -jar jenkins-cli.jar -s http://server create-job newmyjob < myjob.xml

It works fine for me and I am used to store in inside my version control system

There's a plugin called Job Import Plugin that may be what you are looking for. I have used it. It does have issues with importing projects from a server that doesn't allow anonymous access.

For Completeness: If you have command line access to both, you can do the procedure already mentioned by Khez for Moving, Copying and Renaming Jenkins Jobs.

Simple php script worked for me.

Export:

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($jobs as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $path = "http://server1:8080/jenkins/job/".$value."/config.xml";
    $myfile = fopen($value.".xml", "w");
    fwrite($myfile, file_get_contents($path));
    fclose($myfile);
}

Import:

<?php

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($arr as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $cmd = "java -jar jenkins-cli.jar -s http://server2:8080/jenkins/ create-job ".$value." < ".$value.".xml";
    echo exec($cmd);
}

Jenkins export jobs to a directory

 #! /bin/bash
    SAVEIFS=$IFS
    IFS=$(echo -en "\n\b")
    declare -i j=0
    for i in $(java -jar jenkins-cli.jar -s http://server:8080/jenkins list-jobs  --username **** --password ***);
    do
    let "j++";
    echo $j;
    if [ $j -gt 283 ] // If you have more jobs do it in chunks as it will terminate in the middle of the process. So Resume your job from where it ends.
     then
    java -jar jenkins-cli.jar -s http://lxvbmcbma:8080/jenkins get-job --username **** --password **** ${i} > ${i}.xml;
    echo "done";
    fi
    done

Import jobs

for f in *.xml;
do
echo "Processing ${f%.*} file.."; //truncate the .xml extention and load the xml file for job creation
java -jar jenkins-cli.jar -s http://server:8080/jenkins create-job ${f%.*}  < $f
done

Go to your Jenkins server's front page, click on REST API at the bottom of the page:

Create Job

To create a new job, post config.xml to this URL with query parameter name=JOBNAME. You need to send a Content-Type: application/xml header. You'll get 200 status code if the creation is successful, or 4xx/5xx code if it fails. config.xml is the format Jenkins uses to store the project in the file system, so you can see examples of them in the Jenkins home directory, or by retrieving the XML configuration of existing jobs from /job/JOBNAME/config.xml.

It is very easy just download plugin name

Job Import Plugin

Enter the URL of your Remote Jenkins server and it will import the jobs automatically

In my Jenkins instance (version 1.548) the configuration file is at:

/var/lib/jenkins/jobs/-the-project-name-/config.xml

Owned by jenkins user and jenkins group with 644 permissions. Copying the file to and from here should work. I haven't tried changing it directly but have backed-up the config from this spot in case the project needs to be setup again.
