allow for scheduled Registry garbage collection
Provide a way to setup scheduled gargabe collection for the Docker Registry, at least with a helper just as possible with the Omnibus installation (see below), but preferably automated, without manual intervention required.
- as the
gitlab-ctlcommand is not available for CNG, there is not straightforward way for Registry gargabe collection.
- manual gargabe collection is possible, but might lead to data corruption as there is not direct way to put the registry into r/o mode.
- automated, scheduled gargabe collection using a Kubernetes-native approach (i.e. CronJob ressources)
- configurable just as possible for backups
