Docker 최신 버전 설치 / PPA 설정

확인된 시스템: Ubuntu 14.04.3 LTS Ubuntu 16.04.1 LTS Windows 10 professional

Docker 1.11 부터 Docker for Linux, Windows, Mac에 대대적인 기능 변화가 있었다. 이제 Docker를 Windows, Mac, Linux에서 좀 더 편하고 빠르게 쓸 수 있도록 된 것도 그중 하나이다.

2가지 방법들을 적는데 Linux는 모두 할 수 있음을 알린다. 출처: docs.docker.com

1 (Windows, Mac, Linux) 먼저 Windows, Mac은 설치용 파일을 따로 받게 된다.

  • Windows (2016-8-3일 기준)

Windows는 필수 사양이 7, 8, 8.1, 10 이면서 64-bit 이여야 한다. 권장은 pro 또는 enterprise 버젼. 만약 pro 또는 enterprise 가 아니라면 다른 것을 설치하여야 한다.

Windows는 반드시 Hyper-V가 이용 가능한 Windows 10 pro 또는 enterprise 버젼으로 쓰기 바란다. 만약 그렇지 않는다면 Docker Toolbox, Oracle Virtualbox 라는 것들을 설치하여야 한다.

Pro 또는 Enterprise: Hyper-V를 검색하고 만약 검색하고도 보이지 않는다면 설치가 안되있다는 뜻이니 반드시 Windows 기능 켜기/끄기에서 Hyper-V를 활성화 해야 한다.

여기서 부터 7이상 이면서 64-bit 운영체제 이기만 하면 된다.

이제 모두 준비 됬으면 설치한다. 설치 파일(확장자가 msi 이다.)을 사용해 설치.

설치가 다되면 이제 남은 건 확인하는 것이다. cmd, powershell 또는 기타 등등의 Shell을 연다.

다음 명령어를 입력한다. docker run hello-world

반드시 어떤 가이드 같은 것들이 출력되어야 한다. 만약 그렇지 않는다면 문제가 있는 것이다.

출력이 되면 정상적으로 모든 것들이 설치가 된 것이다. 기본 설정이 Windows 시작시 Docker 시작이므로 그냥 쓰면 된다.


  • Mac OS X

Mac은 확인을 하지 않아 적지를 않는다. 하지만 링크를 적어둔다. https://docs.docker.com/toolbox/toolbox_install_mac/

  • Linux

웬만한 Linux 라면 다 된다. --> https://docs.docker.com/engine/installation/linux/ 여기서는 Ubuntu 배포판만 적어둔다. 하지만 위 링크에서 웬만한 배포판에 최적화된 설치 가이드가 주어지니 그걸 읽으면 그렇게 어렵진 않다.

먼저 Kernel이 3.10 이상의 것이여야 한다. 최신 Ubuntu라면 4.x 이상이니 확인할 필요는 없다. Ubuntu 12.04 LTS 이상이면 되므로 최신을 쓰면 이 역시 확인할 필요는 없다.

apt-transport-https 와 ca-certificates, 이 둘이 설치되어야 하는데 이건 운영체제 설치과정에서 주어지므로 하지 않아도 된다. 허나 만약 설치가 안되 있으면 설치한다.

터미널을 열고 그 다음 명령어를 입력한다. --> sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D


명령어를 입력하고 해당 키가 추가되면 /etc/apt/sources.list.d/에서 docker.list 라는 것을 편집해야 한다. 자신이 쓰고자 하는 편집기를 관리자 권한에서 실행하여 편집하면 된다. 없는 경우도 있는데 만들면 된다.

예시: sudo gedit /etc/apt/sources.list.d/docker.list

넣어야 할 내용은 다음 링크를 따라가면 된다. --> https://docs.docker.com/engine/installation/linux/ubuntulinux/#/update-your-apt-sources 버젼 별로 있으니 해당 내용을 읽고 자신 버젼에 맞게 넣으면 끝.

sudo apt-get update 로 설정들을 전부 설치. 만약 lxc-docker 가 있으면 그걸 purge 명령어로 지운다.

이것으로 준비가 되었다. 12.04 LTS는 다음 링크 --> https://docs.docker.com/engine/installation/linux/ubuntulinux/#/prerequisites-by-ubuntu-version

설치하는 단계이다. sudo apt-get install docker-engine 를 입력하고 sudo docker run hello-world로 설치된 docker가 돌아가는지 확인한다. 만약 안되면 sudo service docker start 로 service를 돌려야 한다.

그래도 안되면 무언가 잘못된 것이니 구글링 하는 것이 좋다.

이제 확인 단계는 Windows 처럼 똑같이 무언가 나올 것이다.


정상 설치가 되었는지 여부를 보는 방법

sudo docker run hello-world 를 입력하고 나서 다음 내용이 나오면 정상 설치된 것.

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker Hub account:
 https://hub.docker.com

 https://docs.docker.com/engine/userguide/

2 (Linux에만 해당) 이 내용을 따라하기 위해 먼저 필요한 것: curl이 설치된 Ubuntu, 관리자 권한을 얻기 위한 정보 (curl은 "sudo apt-get install curl" 명령을 사용하여 설치 가능)

다음 명령어를 실행하여 Docker 팀이 제공하는 설치 스크립트를 실행하면, Docker 팀이 관리하는 PPA가 추가되고 최신 버전의 Docker가 설치된다.

이 명령을 실행하기 위해서는 관리자 권한이 필요하기 때문에, 관리자 계정의 비밀번호를 입력하여야 한다.

$ curl -sSL https://get.docker.com/ubuntu/ | sudo sh

상기 주소에서 제공하던 배포판 별 설치 스크립트를 아래 주소로 통합하여 배포판을 자동 인식함.

$ curl -sSL https://get.docker.com/ | sudo sh


실행되는 스크립트의 내용은 아래와 같다.

#!/bin/sh
set -e
#
# This script is meant for quick & easy install via:
#   'curl -sSL https://get.docker.com/ | sh'
# or:
#   'wget -qO- https://get.docker.com/ | sh'
#
# For test builds (ie. release candidates):
#   'curl -fsSL https://test.docker.com/ | sh'
# or:
#   'wget -qO- https://test.docker.com/ | sh'
#
# For experimental builds:
#   'curl -fsSL https://experimental.docker.com/ | sh'
# or:
#   'wget -qO- https://experimental.docker.com/ | sh'
#
# Docker Maintainers:
#   To update this script on https://get.docker.com,
#   use hack/release.sh during a normal release,
#   or the following one-liner for script hotfixes:
#     s3cmd put --acl-public -P hack/install.sh s3://get.docker.com/index
#
