ubuntu docker 설치 및 계정 권한 부여

1. curl 을 통해 docker 를 설치합니다.

$ curl -s https://get.docker.com/ |sudo sh
# Executing docker install script, commit: 49ee7c1
+ sh -c apt-get update -qq >/dev/null
+ sh -c apt-get install -y -qq apt-transport-https ca-certificates curl software-properties-common >/dev/null
+ sh -c curl -fsSL "https://download.docker.com/linux/ubuntu/gpg" | apt-key add -qq - >/dev/null
+ sh -c echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial edge" > /etc/apt/sources.list.d/docker.list
+ [ ubuntu = debian ]
+ sh -c apt-get update -qq >/dev/null
+ sh -c apt-get install -y -qq --no-install-recommends docker-ce >/dev/null
+ sh -c docker version

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
 
  sudo usermod -aG docker your-user
 
Remember that you will have to log out and back in for this to take effect!
 
WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
 

2. docker 설치 여부 확인

$ docker --version
Docker version 17.10.0-ce, build a4aab13

3. docker 관련 계정 권한 부여

$ sudo usermod -aG docker $USER
 

* docker 를 사용하는데 있어서 root 권한이 필요하기 때문에 sudo 명령어 없이 사용하기 위해선 docker 그룹에 추가하여 사용합니다.

* $USER 는 현재 접속 중인 사용자 계정을 뜻합니다.

$ echo $USER
test
 

4. 해당 계정의 권한 부여 후 docker service 를 재시작합니다.

$ sudo service docker restart
 

5. docker service 상태 확인

$ sudo service docker status
