Cleanup Kura Jenkins instance

Summary

While preparing the migration of the Kura Jenkins instance to our new backend storage device, I noticed the following:

• several jobs/branches that did not run in more than a year
• several builds are marked as "Keep forever"
• considerable disk space usage (52 GB)

Some examples:

• The following jobs did not run in more than 2 years:
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-4-1-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-1-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-0-0-release/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-1-0-release/
• Builds of the following jobs are marked as "Keep forever":
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-4-1-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-1-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-2-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-3-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-4-0-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-release-candidate/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-0-0-release/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-1-0-release/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-2-0-release/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-3-0-release/
  • https://ci.eclipse.org/kura/job/kura-release-folder/job/kura-5-4-0-release/

Tasks

• Please consider all build jobs during clean up and decide if they are still needed.

• Please keep in mind that Jenkins is not a file server to archive build artifacts. Any build artifacts that should be kept around for some time, should be copied to the project's download directory at download.eclipse.org. Therefore, marking builds as "keep forever" is deprecated and should only be used temporarily, if ever.

Hi Frederic, thanks for the heads up. We were keeping certain builds available as a matter of way to check and validate in case of reported issues, tracing back to the whole process of build, validation and distribution. Later we have revised this process, but those parameters were left there on those old builds. We'll review them in the next days and free resources.

Best regards, Matteo
