[Script] Docker & Docker compose를 명령 한 번으로 설치

0. INTRO

• Docker 및 Docker-compose 실행 명령을 하나의 쉘 스크립트에 담아 쉘 스크립트 실행 명령 한 번으로 두 기능이 모두 설치되도록 script를 만들었다.
• EC2 인스턴트를 새롭게 만들때 user data에 명시하여 start와 동시에 자동 설치되게 하거나 인스턴트 start 후 접속하여 설치할 때 아주 용이하게 사용이 가능할 것이다.

1. Ubuntu에서 Docker 및 Docker-compose Install/Uninstall

• docker_install.sh

  #!/bin/bash
  echo "==========================================="
  echo "DOCKER INSTALL START!"
  echo "==========================================="
  
  sudo apt-get update -y &&\
      apt-transport-https &&\
      ca-certificates &&\
      curl &&\
      software-properties-common
  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
  sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
  sudo apt update
  apt-cache policy docker-ce
  sudo apt install -y docker-ce
  sudo usermod -aG docker $USER
  
  # install docker-compose
  sudo apt-get install docker-compose-plugin
  
  echo "DOCKER VERSION : $(docker --version)"
  echo "DOCKER COMPOSE VERSION : $(docker compose version)"

• docker_uninstall.sh

  #!/bin/bash
  
  echo "==========================================="
  echo "DOCKER UNINSTALL START!"
  echo "==========================================="
  
  sudo apt-get purge -y docker-engine docker docker.io docker-ce
  sudo apt-get autoremove -y --purge docker-engine docker docker.io docker-ce
  sudo rm -rf /var/lib/docker /etc/docker
  sudo rm /etc/apparmor.d/docker
  sudo groupdel docker
  sudo rm -rf /var/run/docker.sock
  sudo rm -rf /usr/local/bin/docker-compose
  sudo rm -rf /etc/docker
  sudo rm -rf ~/.docker
  
  echo "==========================================="
  echo "DOCKER UNINSTALLED!"
  echo "==========================================="

2. CentOS에서 Docker Install

• docker_install.sh

  #!/bin/bash
  
  sudo yum -y update
  sudo yum docker install -y
  sudo systemctl start docker
  sudo systemctl enable docker 
  sudo systemctl status docker

3. Shell Script 실행

bash docker_install.sh
