Docker-compose

컨테이너를 사용하기 위해 CentOS에 Docker / Docker-compose 를 설치 및 설정에 대해서 정리한 문서를 작성합니다.

0. Enviroment

OS : CentOS 7
Docker : 19.03
Docker-Compose : 1.27.4

1. Default Enviroment Setting

mkdir -p /usr/local/umount/Src/docker
mkdir -p /usr/local/umount/Download

2. Install Docker

yum -y install yum-utils
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache
yum -y install docker-ce

3. Auto start & User permission setting

systemctl enable --now docker
usermod -aG docker $USER

Docker는 기본적으로 root권한으로 실행되며, sudo 없이 사용하기 위해서 권한 설정을 해 줘야 합니다.

4. Install docker-compose

version=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep 'tag_name' | cut -d\" -f4)
curl -L https://github.com/docker/compose/releases/download/${version}/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
curl -L https://raw.githubusercontent.com/docker/compose/${version}/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose
source /etc/bash_completion.d/docker-compose

최신 버전을 받기 위한 방법이며 특정 버전을 받고 싶으면 version의 값을 원하는 값으로 하시면 됩니다.
