Docker를 설치합니다. (Windows, Mac, Linux)

Windows에 설치합니다.

https://store.docker.com/editions/community/docker-ce-desktop-windows

설치 파일을 받아 실행합니다. 설치 과정에서 Windows가 재시작할 수 있습니다.

설치가 완료되면 Windows Tray에 Docker 아이콘이 생성됩니다.

정상적으로 설치가 되었는지 cmd창을 열고 버전을 확인해 봅니다.

C:\Users\jake>docker --version
Docker version 17.12.0-ce, build c97c6d6

C:\Users\jake>docker-compose --version
docker-compose version 1.18.0, build 8dd22a96

C:\Users\jake>docker-machine --version
docker-machine version 0.13.0, build 9ba6da9

Mac에 설치합니다.

https://docs.docker.com/docker-for-mac/install

Docker.dmg 파일을 다운받아 설치합니다. 실치가 완료되면 Mac의 메뉴바에 아이콘이 보입니다.

terminal을 열어 버전과 info를 확인해 봅니다.

Docker repository를 추가합니다.

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

apt-get을 업데이트 합니다.

$ sudo apt-get update

Docker를 설치할 수 있는지 확인합니다.

$ apt-cache policy docker-ce

위 메시지는 docker-ce가 설치된것은 아니며 repository에 존재하는 것을 확인합니다.

이제 Docker를 설치합니다.

$ sudo apt-get install -y docker-ce

Docker가 정상적으로 실행되고 있는지 확인해 봅니다.
