Scan the jobs of Jenkins, delete old builds:
-
Only deletes builds older than
DeleteWhenOlderThanDays(10 now). -
Keep some builds (the last
KeepLastBuilds = 10builds since any "permalink" build like "last successful" etc. builds) always, regardless of age. -
Does the job only if not
DryRun. On the command-line, pass--really-removeto setDryRun := false. First run without it (make dry run) to see what would be deleted, and how much disk space would be freed.
This program does the removals in "direct" way, i.e. just accesses the filesystem, not using any official Jenkins API.
So it is light-weight and will work reliably regardless of what Jenkins is doing and how much is Jenkins responsive over www. And still you can run this process while Jenkins is running in parallel because this script will only change (remove) really old directories (older than DeleteWhenOlderThanDays = 40). So the Jenkins process should not be doing anything in these dirs.
-
Make sure you like defaults at the beginning of the code in
jenkins_disk_cleanup.dpr. Adjust them as needed, esp.BaseJenkinsJobsDir. -
Compile with Castle Game Engine. Use build tool (command-line) or editor.
-
Copy the binary to your server. You can adjust and use
deploy.shto have a ready script to build + copy. -
Run on the server. Do a first run without any arguments. Do it as any user that has at least read access to builds dir (so, likely you don't need
sudo). -
Then run as a user that can actually delete, and add
--really-removeargument. So, likely withsudo.I recommend to run in Emacs shell buffer (have easily scrollable and as-long-as-necessary command history) inside Tmux (kill the terminal freely, go back to it later to check task progress).
-
Once you're confident it works nicely, add executing it to cron. E.g. to
/etc/cron.weekly/cag-jenkins-cleanup.
Implemented with Pascal using Castle Game Engine units.
