I have deployed Jenkins in my CentOS machine, Jenkins was working well for 3 days, but yesterday there was a Disk space is too low. Only 1.019GB left.

I have a cleanup job with the following build steps. You can schedule it @daily or @weekly.

1. Execute system groovy script build step to clean up old jobs:

    import jenkins.model.Jenkins
    import hudson.model.Job

    BUILDS_TO_KEEP = 5

    for (job in Jenkins.instance.items) {
      println job.name

      def recent = job.builds.limit(BUILDS_TO_KEEP)

      for (build in job.builds) {
        if (!recent.contains(build)) {
          println "Preparing to delete: " + build
          build.delete()
        }
      }
    }

You'd need to have Groovy plugin installed.

2. Execute shell build step to clean cache directories

rm -r ~/.gradle/
rm -r ~/.m2/

echo "Disk space"
du -h -s /
