We have an old Jenkins with a bunch of iOS jobs which needs to be copied to a new Jenkins instance.
Documentation suggests to:
Move a job from one installation of Jenkins to another by simply copying the corresponding job directory.
I.e. the first solution is just to copy a whole
jobs directory or copy a per-project job’s catalog.
Disadvantage (or advantage – depends on an exact task) of such approach is that with a job’s directory a whole its history, artifacts, logs etc will be copied as well.
Another solution is to use the Jenkins CLI and allows to copy a full job’s configuration – but it will be created “from scratch”.
Go to Manage Jenkins > Jenkins CLI and download the CLI’s jar-file:
sudo wget -O /usr/local/bin/jenkins-cli.jar https://jenkins.example.com/jnlpJars/jenkins-cli.jar
Check it – in
-auth pass your user:pass or user:api_token, in
-s – Jenkin’s host URL, here it’s running locally using Jenkin’s own CLI file:
root@jenkins:/backups# java -jar /data/jenkins/war/WEB-INF/jenkins-cli.jar -auth user:pass -s http://localhost:8080/ version
Now import the Unit Test job from the iOS Projectname directory into the
root@jenkins:/backups# java -jar /data/jenkins/war/WEB-INF/jenkins-cli.jar -auth user:pass -s http://localhost:8080/ get-job 'iOS Projectname/Unit Test' > Projectname_Unit_Test_job.xml
Check the file’s content:
root@jenkins:/backups# head Projectname_Unit_Test_job.xml
<?xml version='1.0' encoding='UTF-8'?>
<description>Runs test, and delivers feedback to slack</description>
And export it to the iOS Projectname on a new Jenkins server: read the file’s content using the
cat and then pass data to the CLI via pipe
root@jenkins:/backups# cat Projectname_Unit_Test_job.xml | java -jar /data/jenkins/war/WEB-INF/jenkins-cli.jar -auth user:pass -s https://ci.example.com create-job 'iOS Projectname/Unit Test'
