| // This is a Jenkinsfile that backs up (parts of) Jenkins. | |
| // | |
| // So why not use the SCM-sync plugin? I've found it's just not configurable | |
| // enough, and if something goes wrong it's a lot more opaque than this technique | |
| // which uses standard shell and git commands. | |
| // | |
| // By default this approach covers users, credentials, and job and plugin configs, | |
| // but not full builds/workspaces. Obviously you want to send this stuff only to | |
| // a private repository! If you want to change the files that are included to | |
| // add or remove files from consideration with the backup, edit the shell script | |
| // section below. Make sure this job is pinned to your Jenkins master using your | |
| // preferred technique for that. | |
| // | |
| // The job that executes this Jenkinsfile should describe three parameters: | |
| // | |
| // * BACKUP_REPO: | |
| // a string representing the repo you want your backup's pushed to | |
| // | |
| // * BACKUP_BRANCH: | |
| // a string representing where you want backup's pushed to | |
| // | |
| // * GIT_CREDENTIAL_ID: | |
| // a string representing the Jenkins credential id for | |
| // i.e. your github deploy key SSH. See the /credentials | |
| // URL on your Jenkins server to add a new SSH key, and make | |
| // sure that the username is `git`. Add github deployment keys | |
| // at i.e. https://github.com/$user/$project/settings/keys. Make | |
| // sure your key allows push and isn't read-only. | |
