### 3.1 Automatic removal of non current objects versions

A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

e.g., To scan objects stored under `user-uploads/` prefix and remove versions older than one year.

### 2. Create a new user with canned policy

Use [`mc admin policy`](https://docs.min.io/community/minio-object-store/reference/minio-mc-admin/mc-admin-policy.html) to create canned policies. Server provides a default set of canned policies namely `writeonly`, `readonly` and `readwrite` *(these policies apply to all resources on the server)*. These can be overridden by custom policies using `mc admin policy` command.

ConfigMaps are also allowed) that kubectl can use to accurately and efficiently track set membership across `apply` operations. The format used for `ApplySet` is set out in  [KEP 3659](https://github.com/kubernetes/enhancements/issues/3659) as a low-level specification.  Other tools in the ecosystem can also build on this specification for improved interoperability.  To try the ApplySet-based pruning alpha, set `KUBECTL_APPLYSET=true` and use the flags `--prune --applyset=secret-name` with `kubectl...
