1. 컨테이너 기술이란 무엇입니까? (100자 이내로 요약) | ||
|
||
컨테이너란 '모듈화되고, 격리된 컴퓨팅 환경'을 의미한다. | ||
기존의 VM은 가상화를 위해 하이퍼바이저와 게스트OS가 필요했는데, 컨테이너는 운영체제를 제외하고 어플리케이션 실행에 필요한 모든 파일만 패키징한 형태이므로 VM보다 훨씬 가볍고 빠르게 동작이 가능 | ||

2. 도커란 무엇입니까? (100자 이내로 요약) | ||
|
||
도커란 리눅스 컨테이너에 리눅스 어플리케이션을 프로세스 격리기술을 사용하여 더 쉽게 | ||
컨테이로 실행하고 관리할 수 있게 하는 오픈소스 프로젝트다. | ||

||
도커이미지) | ||
컨테이너를 만들때 사용되는 읽기전용 템플릿이다. 도커컨테이너를 생성할때 필요한 요소이며 iso 파일과 비슷한 개념이다. | ||
도커이미지와 도커컨테이너는 1:N의 관계이다. | ||

도커 컨테이너) | ||
도커 이미지로 생성되는 인스턴트이다. | ||
가상화된 공간을 생성할때 리눅스 자체기능을 사용하여 프로세스 단위의 격리환경을 만드므로 성능손실이 없음 | ||
