There are changes that may reduce disc use, but even with those changes, Jenkins uses disc space and will continue to use disc space as you use it more. Some of the techniques that can reduce disc use: - Use the GitHub branch source plugin (or the Bitbucket branch source plugin or the Gitea plugin) in the multi-branch pipeline job definition rather than the git plugin. Those higher level branch source plugins obtain the Jenkinsfile without using a full checkout (so long as you don't disable lightweight checkout) - Maintain a git reference repository on each agent with a reasonably current copy of the repositories, then add the path to that reference repository to the job definition. The CloudBees support article about reference repositories <https://support.cloudbees.com/hc/en-us/articles/115001728812-Using-a-Git-reference-repository> is very helpful. I gave a 10 minute talk at Jenkins World 2017 "Git in the Large <https://www.slideshare.net/markewaite/git-inthelarge>" that may help. I also gave a 10 minute talk at Jenkins World 2016 "Jenkins hints for large git repos <https://jenkins.io/files/2016/jenkins-world/large-git-repos.pdf>". Those two talks are available on youtube (2017 <https://youtu.be/jBGFjFc6Jf8?t=6431>, 2016 <https://youtu.be/TsWkZLLU-s4?t=137>) if needed - Honor the refspec on checkout (already done by multi-branch pipeline, not done by default for freestyle projects or matrix projects) - Keep your pipeline library git repositories small and focused on only providing pipeline libraries. Don't include content in a pipeline library that is not needed for the pipeline library - Create a new git repository which uses "git lfs" instead of storing large files directly in the repository Thanks, Mark Waite > > *More details:* > > > 1.
