Start into maintenance mode

[Michael Rumpf]

Hi,

the usual way to restart Jenkins for maintenance is to activate "Prepare for shutdown", to wait until all running tasks are completed and restart Jenkins.

In the past we had many situations where we needed a second restart but because Jenkins starts looking for SCM changes right after the start a new set of builds are already running.

It would be of great benefit to have a flag which starts Jenkins right into "Prepare for shutdown" mode so that no new builds start running.

The easiest part would be to look for a certain file, e.g. jenkins.maintenance, if that is present, Jenkins goes into maintenance mode. When the file is deleted, Jenkins goes back to normal mode.

How do you think about such a feature?

Kind regards,

     Michael

I do agree. Jenkins should stay in the maintenance mode until requested to cancel by an administrator

There are instructions at the following page for getting jenkins to start in maintenance mode:

https://wiki.jenkins-ci.org/display/JENKINS/Post-initialization+script

You can create a Groovy script file as $JENKINS_HOME/init.groovy

With the following contents:

import jenkins.model.*;

// start in the state that doesn't do any build.
Jenkins.instance.doQuietDown();

On a related note, I would like to be able to manually trigger and allow some maintenance jobs to run when Jenkins is in maintenance mode...

Hope this helps,

Geoff

FYI, there is a proprietary plugin in Jenkins Enterprise by CloudBees
for this purpose.

Thanks for the hint, this will definitely be of help for our purpose.

I find no trace of it on the Cloudbees page:

http://www.cloudbees.com/jenkins-enterprise-by-cloudbees-available-plugins.cb

However, I will download a trial version and have a look.

Thanks,

That page is incomplete.

Use http://release-notes.cloudbees.com/ for the complete reference (it's the "CloudBees Quiet Start Plugin").
