# v1.3.0-alpha.2

리눅스 컨테이너를 사용하는 데에는 **보안**, **반복 가능성**, **단순함** 등의 장점이 있습니다.

* removed unsafe double RLock in cpumanager ([#62464](https://github.com/kubernetes/kubernetes/pull/62464), [@choury](https://github.com/choury))
* Fix container StartTime in the kubelet's stats/summary endpoint ([#64229](https://github.com/kubernetes/kubernetes/pull/64229), [@dashpole](https://github.com/dashpole))

```

* Fix fetching pids running in a cgroup, which caused problems with OOM score adjustments & setting the /system cgroup ("misc" in the summary API). ([#36614](https://github.com/kubernetes/kubernetes/pull/36614), [@timstclair](https://github.com/timstclair))

Linuxコンテナの使用には、**セキュリティ**、**反復可能性（レプリカビリティ）**、**シンプリシティ**など、いくつかの利点があります。
