Add a note that after a cluster upgrade using kubeadm, backup files will need to be cleared manually.
davidwtf opened this issue · comments
After the upgrade, the backup directory /etc/kubernetes/tmp
will remain.
The ETCD backup could use several hundred MB to several GB of disk storage.
If we don't clean up the backups, the storage may become full after several upgrades.
Users may need to clean it up manually.
