Docker compose---安裝

1. 簡介

Compose 是 docker 提供的一個指令行工具，用來定義和運作由多個容器組成的應用。

使用 compose，我們可以通過 YAML 檔案聲明式的定義應用程式的各個服務，并由單個指令完成應用的建立和啟動。

Compose 的使用方式非常簡單，基本上就是下面的三闆斧：

• 定義 Dockerfile
• 定義 docker-compose.yml

• 運作 docker-compose up

  其實 compose 提供的指令可以管理應用的整個生命周期：

• Start, stop, rebuild services
• 檢視運作中 service 的狀态
• 輸出運作中 service 的日志
• 在 service 中執行一次性的指令

2. 安裝Docker compose

安裝 Docker Compose 前請先在本地安裝 Docker

安裝dockercompose的方式有兩種，curl和pip兩種，本文直接附上安裝腳本，腳本直接安裝docker和dockercompose

#!/bin/bash
DEBIAN=$(uname -v |grep -o Debian)
CENTOS=$( uname -r |grep -o el7)
read -p "please enter hostname:  " hostname
hostnamectl set-hostname $hostname
