### Test using MinIO Client `mc`

`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services.

The following commands set a local alias, validate the server information, create a bucket, copy data to that bucket, and list the contents of the bucket.

- Kubeadm: fixed a bug where the path of the manifest can not be specified when `kubeadm upgrade diff` specified a config file, and the `--api-server-manifest`, `--controller-manager-manifest` and `--scheduler-manifest` flags of `kubeadm upgrade diff` are marked as deprecated and will be removed in a future release.
