CentOS 7 安裝 docker-compose

根據官方文件教學，看起來是適用所有Linux system。

1. 下載stable release的docker-compose binary: curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2. 給予執行權限: chmod +x /usr/local/bin/docker-compose

3. 測試安裝是否完成: docker-compose --version

若出現找不到docker-compose指令，執行以下cmd: $ ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
