Overview

Docker 사용법 정리

Basic

Docker 에는 크게 두가지 버전이 있다. CE(Community Edition) 과 EE(Enterprise Edition)이다. CE 는 개인/개발용 무료버전, EE 는 기업/상품용 유료 제품이다.

Installation

Commands

attach

현재 동작중인 container 에 접속한다. 

$ sudo docker attach --help

Usage:	docker attach [OPTIONS] CONTAINER

Attach local standard input, output, and error streams to a running container

Options:
      --detach-keys string   Override the key sequence for detaching a container
      --help                 Print usage
      --no-stdin             Do not attach STDIN
      --sig-proxy            Proxy all received signals to the process (default true)

Ctrl+P, Ctrl+Q 를 차례대로 입력하면 컨테이너를 정지하지 않고, 빠져나올 수 있다.

exec

외부에서 현재 running 중인 container 안의 명령을 실행한다. 

$ sudo docker exec --help

Usage:	docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

Run a command in a running container

Options:
  -d, --detach               Detached mode: run command in the background
      --detach-keys string   Override the key sequence for detaching a container
  -e, --env list             Set environment variables
      --help                 Print usage
  -i, --interactive          Keep STDIN open even if not attached
      --privileged           Give extended privileges to the command
  -t, --tty                  Allocate a pseudo-TTY
  -u, --user string          Username or UID (format: <name|uid>[:<group|gid>])

컨테이너 이름 대신 컨테이너 ID 를 사용해도 된다. 하지만 컨테이너가 running 상태인 경우에만 사용할 수 있으며, stop 상태에서는 사용할 수 없다.
