구차니의 잡동사니 모음

화장실로 물이 새서 공사한다고 오가는 신세라.. 힘드네

검색하다 보면 window에 있다는데 구버전(5.x) 에서나 그랬지

그 이후 버전에는 view로 옮겨진듯

cpu와 ram에 대한건 보이는데 디스크에 대한건 안보이네?

큭.. 심심해서(!) 게임해보려고 했던 나의 계획은 이렇게 물건너 가고.. ㅠㅠ

(요건 바이오쇼크 인피니트.. 망할 openGL 4.1)

시리어스 샘 3는 서바이벌 모드로 기본설정으로 해보는데

노트북 해상도가 낮아서(1280x800) 그나마 33~40 프레임은 나와주는 듯

검콩으로 게임은 못하니 금세 얻어맞고 끝이지만 ㅠㅠ

아래의 두개를 깔아야 하는데 문제는 sudo로 깔아서

일반유저로 사용하면 경로에 파일이 없다고 하는데..

어쩔수 없이 root 권한으로 실행하면 정상적으로 나오긴 한다.

docker는 vm이 아니다.

어쩌면 이게 정말 핵심인데

docker내부에서 어떠한 서비스가 실행되는게 아니라면

이미지로 부터 생성되는 컨테이너는 바로 exit 상태로 전환된다.

docker pull 을 통해서 image를 docker hub 로 부터 받고

docker create로 image에서 container로 만들고 

docker start로 container의 설정파일대로 실행하게 된다.

docker attach로 tty를 해당 도커의 stdin/stdout에 붙여준다.

docker run은 pull + create + start를 하나로 합친 명령어이다.

그런 관계로 docker 내부의 서비스가 죽어서 exited가 되면

docker start [containerid]로 구동을 시키면 되겠지만..

어떤 원인이 있어서 죽은 거테니.. 다음번에 다시 시도해봐야겠네?
