Docker Command 정리 #01
문서버전: 2018.02.20 v0.1
docker help 명령어 확인시 아래와 같은 명령어를 확인 할수 있습니다.
자주 사용하는 명령어 위주로 정리 하였습니다.
일부 내용의 오타가 있을수 있습니다. 🙂
옵션 부분의 경우 차후 정리할 예정입니다.
test@docker-test01:~$ docker help

docker attach 커맨드를 이용하여 ssh-server 컨테이너에 접속을 하였지만 접속이 안되는것처럼 보입니다.??
docker 명령어 입력마지막 부분에 /bin/bash 를 입력 하지 않을경우 위와같이 접속만 되어 있습니다.
Ctrl+\ 를 입력하여 attach를 종료 합니다.
종료후 아래와 같이 컨테이너가 종료 합니다.
test@docker-test02:~$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES test@docker-test02:~$
Ctrl+ p q 입력시 아래와 같이 컨테이너 실행상태에서 나올수 있습니다.

docker attach 로 컨테이너에 접속하기 위해서는 -d -it 옵션을 사용해야 합니다.
