[Docker] 도커 간단하게 설치하자

도커를 설치하기 위해 이것 저것 명령어들이 많다.

가뜩이나 잘 모르겠는데, 한줄 한줄 설치할때 모르고 진행할 때가 대부분이며, 필자도 가이드만 있으면 따라할 뿐 알면서 따라하는 건 아니다.

하지만 도커를 설치할 때 쉘 하나로 설치할 수 있도록 제공하고 있으니, 참고하기 바란다.

참고로 한줄 씩 이해하면서 설치하고 싶을 경우 아래 도커 사이트에서 OS 환경별로 설치 방법이 있으니 궁금할 경우 방문하여 보기 바란다.

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.


To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker.com/go/attack-surface/

docker-compose를 설치하기 전 pip3가 설치되어 있어야합니다. python3 및 pip3가 설치되지 않은경우 다음 코드를 통해 설치합니다

sudo apt-get install libffi-dev libssl-dev
sudo apt install python3-dev
sudo apt-get install -y python3 python3-pip

libffi-dev, libssl-dev 설치 화면

python3과 pip3가 설치되면 다음 코드로 docker-compose를 설치합니다

sudo pip3 install docker-compose
