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.
