* Um programa específico enquanto está **em execução** no sistema operacional.
    * Isso não se refere ao arquivo, nem ao código, refere-se **especificamente** à coisa que está sendo **executada** e gerenciada pelo sistema operacional.

### 시작 시 실행을 위한 도구 예시 { #example-tools-to-run-at-startup }

이 역할을 할 수 있는 도구 예시는 다음과 같습니다:

* Docker
* Kubernetes
* Docker Compose
* Swarm Mode의 Docker
* Systemd
* Supervisor
* 클라우드 제공자가 서비스 일부로 내부적으로 처리
* 기타...

다음 장에서 더 구체적인 예시를 제공하겠습니다.

## 재시작 { #restarts }

애플리케이션이 시작 시 실행되도록 보장하는 것과 비슷하게, 장애가 발생했을 때 **재시작**되도록 보장하고 싶을 것입니다.

- Kubelet no longer attempts to sync iptables on non-Linux systems.. ([#67690](https://github.com/kubernetes/kubernetes/pull/67690), [@feiskyer](https://github.com/feiskyer))
- Kubelet no longer applies default hard evictions of nodefs.inodesFree on non-Linux systems. ([#67709](https://github.com/kubernetes/kubernetes/pull/67709), [@feiskyer](https://github.com/feiskyer))

* fuse daemons for GlusterFS and CephFS are now run in their own systemd scope when Kubernetes runs on a system with systemd. ([#49640](https://github.com/kubernetes/kubernetes/pull/49640), [@jsafrane](https://github.com/jsafrane))

### Introducing Graceful Node Shutdown (Alpha)

The `GracefulNodeShutdown` feature is now in Alpha. This allows kubelet to be aware of node system shutdowns, enabling graceful termination of pods during a system shutdown. This feature can be [enabled through feature gate](https://docs.k8s.io/concepts/architecture/nodes/#graceful-node-shutdown).

### Runtime log sanitation

### 起動時に実行するツールの例 { #example-tools-to-run-at-startup }

実行するツールの例をいくつか挙げます:

* Docker
* Kubernetes
* Docker Compose
* Swarm モードによる Docker
* Systemd
* Supervisor
* クラウドプロバイダーがサービスの一部として内部的に処理
* そのほか...

次の章で、より具体的な例を挙げていきます。

## 再起動 { #restarts }

起動時にアプリケーションが実行されることを確認するのと同様に、失敗後にアプリケーションが**再起動**されることも確認したいと思われます。
