### Bug or Regression

- CVE-2020-8557 (Medium): Node-local denial of service via container /etc/hosts file. See https://github.com/kubernetes/kubernetes/issues/93032 for more details. ([#92916](https://github.com/kubernetes/kubernetes/pull/92916), [@joelsmith](https://github.com/joelsmith)) [SIG Node]

* Add support for 3rd party objects to kubectl ([#18835](https://github.com/kubernetes/kubernetes/pull/18835), [@brendandburns](https://github.com/brendandburns))
* Remove unnecessary override of /etc/init.d/docker on containervm image. ([#23593](https://github.com/kubernetes/kubernetes/pull/23593), [@dchen1107](https://github.com/dchen1107))

			// Make sure to return object info to provide extra information.
			return &GetObjectReader{
				ObjInfo: objInfo,
			}, err
		}

		// Zero byte objects don't even need to further initialize pipes etc.
		return NewGetObjectReaderFromReader(bytes.NewReader(nil), objInfo, opts)
	}

	if objInfo.IsRemote() {
		gr, err := getTransitionedObjectReader(ctx, bucket, object, rs, h, objInfo, opts)
		if err != nil {

* Fix a bug affecting nested data volumes such as secret, configmap, etc. ([#57422](https://github.com/kubernetes/kubernetes/pull/57422), [@joelsmith](https://github.com/joelsmith))

予め作成されたコンテナ・イメージを使用することで、異なるツールを**組み合わせて**使用することが非常に簡単になります。例えば、新しいデータベースを試す場合に特に便利です。ほとんどの場合、**公式イメージ**を使い、環境変数で設定するだけで良いです。

そうすれば多くの場合、コンテナとDockerについて学び、その知識をさまざまなツールやコンポーネントによって再利用することができます。
