Workspace cleanup after job removal

[Bertrand Renuart]

Dear all,

 

After some investigations, it appears Jenkins doesn’t cleanup a job’s (latest) workspace after the corresponding job definition is removed.

Is it on purpose or is there any configuration parameter I could tweak to enable such workspace garbage collection ?

 

Thanks for your advices,

 

/Bertrand

Hi Bertrand,

I am a bit confused. Are you talking about DELETING the job itself and the workspace remains or after spawning a build job?
If you delete a job in Jenkins should everything be gone.
There is a plugin called Jenkins Workspace Cleanup Plugin to clean the workspace before or after a build job.

Take care
Jan

I’m talking about DELETING the job through the UI on master.

In this case, the corresponding workspace remains on our single slave.

[Jan Seidel]

Weird.

I know only about this issue if more than one workspace is available.

Hi Bertrand,

Jenkins does not explicitly delete the workspace of a job when deleting
the job.

But if your job happens to reside on the master and your workspace
happens to reside within your job directory (this is the default),
deleting the job will also remove its workspace implicitly.

If your workspace resides on a slave or outside your job directory,
Jenkins will not delete it. I guess, this would be also tricky to
implement: First, it would require Jenkins to keep a list of all slaves
that have ever built that very job. Second, a slave might be off-line
during job removal. What would happen with the workspace on this slave
then? Will it be deleted, when the slave comes on-line again?

Sorry, no extended magic here - yet ;O).

Cheers,
Simon.

For those that are interested, I solved the issue by writing a small Groovy script that gets executed periodically.
This script goes through the online slaves, list the content of their workspaces and delete any subdirectories whose name does not match any existing job configuration. It must be executed on the master node (apparently slaves do not have access to job configuration - which seems normal).

The script is available at http://snipt.org/ujhhd4.

Unfortunately, only the slaves that are online at the time the script is executed are cleaned up... Ideally, the script should also be executed when a slave connects. For that reason, I'm thinking about writing a java plugin for Jenkins that would handle the cleanup.

Hi Bertrand,

[Kamal Ahmed]

Well,
I removed jenkins via ' apt-get remove jenkins
then manually removed /etc/init.d/jenkins

Now when i install Jenkins  via qpt-get install jenkins, it does not restore the /etc/init.d/jenkins file back.

Any suggestions ?
Thanks,
-Kamal.

If you delete with apt get remove jenkins --purge parameters all files should be removed from your computer. Then you can install with apt get install jenkins command. Then I think stratup script should be emerge

You may need to remove configuration files[1] in order to persuade apt-get install that the package has been completely removed, before installing again.

Hi Bertrand,

Would you mind to share your script again please?
