왜 Docker를 사용해야하는가?

Why Should I Care (For Developers)

"나에게 Docker의 매력은 간단히 격리된 환경을 만들 수 있다는 것과, 그러한 환경을 재사용할 수 있다는 점이다."런타임 환경을 한 번 만들어 패키지로 만들면, 이 패키지를 다른 어떤 머신에서도 다시 사용할 수 있다. 또한 여기서 실행되는 모든 것은 마치 가상머신과 같이 호스트로부터 격리되어있다. 무엇보다도 이런 모든 일들이 빠르고 간단히 가능하다.

    Adventures in Python Core Dumping

After watching Bryan Cantrill's presentation on
[Running Aground: Debugging Docker in Production][aground] I got all
excited (and strangely nostalgic) about the possibility of
core-dumping server-side Python apps whenever they go awry. This would
theoretically allow me to fully inspect the state of the program
at the point it exploded, rather than relying solely on the information
of a stack trace.
