Charts: [stable/jenkins] external backup and restore of job history

FEATURE REQUEST

Current version of jenkins helm chart doesn't support external backup and restore mechanism for job history (some people use it for apps versioning).

For temporary solution I have init-container running along with jenkins-master which backups in some period of time.

tar -C /var/jenkins_home -z --exclude jobs/*/config.xml --exclude jobs/*/workspace* --exclude jobs/*/simulation.log -c config-history jobs -f backup

then backup can be uploaded e.g. to s3 bucket and restored during jenkins startup.

But there are some limitation of this approach.

Which chart:
stable/jenkins

I would vote for this feature. It would be of great interest to have a way to restore the job history. Even on an chart upgrade.

@svyotov @muehlburger ok guys, if you want I can make a PR with automated backup and restore in place :)
but the question is - will it be accepted as a solution?
