History Cleanup
It is recommended to enable the place cleaning cron job by enabling the cleaning maintenance script:
helm upgrade des des-<VERSION>.tgz \
--namespace des \
--reuse-values \
--set clean.enabled=true
The cleanup script runs each first day of the month to clean old versions of files. By default, it has a policy to keep at least all files modified within 90 days, the last 3 versions and all tagged versions.
