- The slow initialization of container runtime will not cause System WatchDog to kill kubelet. Device Manager is not considered healthy before it attempted to start listening on the port.

* 운영체제에서 **실행 중**인 특정 프로그램
    * 파일이나 코드를 의미하는 것이 아니라, 운영체제가 **실제로 실행**하고 관리하는 대상을 **구체적으로** 의미합니다.
* 어떤 프로그램이든 어떤 코드든, **실행**될 때만 무언가를 **할 수 있습니다**. 즉, **프로세스가 실행 중**일 때입니다.
* 프로세스는 여러분이, 혹은 운영체제가 **종료**(또는 “kill”)할 수 있습니다. 그러면 실행이 멈추고, 더 이상 **아무것도 할 수 없습니다**.
* 컴퓨터에서 실행 중인 각 애플리케이션 뒤에는 프로세스가 있습니다. 실행 중인 프로그램, 각 창 등도 마찬가지입니다. 그리고 컴퓨터가 켜져 있는 동안 보통 많은 프로세스가 **동시에** 실행됩니다.
* **같은 프로그램**의 **여러 프로세스**가 동시에 실행될 수도 있습니다.

  * Kubernetes now shares a single PID namespace among all containers in a pod when running with docker >= 1.13.1. This means processes can now signal processes in other containers in a pod, but it also means that the `kubectl exec {pod} kill 1` pattern will cause the Pod to be restarted rather than a single container.

- If using cgroups v2, then the cgroup aware OOM killer will be enabled for container cgroups via  `memory.oom.group` .  This causes processes within the cgroup to be treated as a unit and killed simultaneously in the event of an OOM kill on any process in the cgroup.
