バーチャルマシンみたいに使う場合の構成。

プロセス毎にコンテナ作るのが正当ですが、開発環境なら１つにまとめちゃって配布してもOK。

 

 

docker-composeインストール

sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

一度ログインし直す(重要)
$ exit

 

$ docker-compose -v
docker-compose version 1.22.0, build f46880fe

 

Dockerインストール

$ sudo yum install -y docker
$ sudo usermod -aG docker ${USER}

sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker

 

$ mkdir -p $HOME/docker-lamp/{mysql,php,centos}
$ mkdir -p $HOME/docker-lamp/data/{html,db}

 

Docker 構成ファイル作成

$ vi $HOME/docker-lamp/data/html/index.php


<?php

echo "Hello Docker-Lamp!";

 

$ vi $HOME/docker-lamp/docker-compose.yml
