+# Docker Compose
+
+>  [compose](https://github.com/docker/compose) 项目是 Docker 官方的开源项目，负责实现对 Docker 容器集群的快速编排。从功能上看，跟 `OpenStack` 中的 `Heat` 十分类似。 
+
+## 一、Compose 简介
+
+**`Compose` 的定位是：定义和运行多个 Docker 容器的应用**。 使用一个 `Dockerfile` 模板文件，可以让用户很方便的定义一个单独的应用容器。然而，在日常工作中，经常会碰到需要多个容器相互配合来完成某项任务的情况。例如要实现一个 Web 项目，除了 Web 服务容器本身，往往还需要再加上后端的数据库服务容器，甚至还包括负载均衡容器等。 
+
+`Compose` 恰好满足了这样的需求。它允许用户通过一个单独的 `docker-compose.yml` 模板文件（YAML 格式）来定义一组相关联的应用容器为一个项目（project）。 
+
+`Compose` 中有两个重要的概念：
+
+- **服务 (`service`)**：一个应用的容器，实际上可以包括若干运行相同镜像的容器实例。
+- **项目 (`project`)**：由一组关联的应用容器组成的一个完整业务单元，在 `docker-compose.yml` 文件中定义。
+
+ `Compose` 的默认管理对象是项目，通过子命令对项目中的一组容器进行便捷地生命周期管理。 
+
+## 二、安装卸载
+
+`Compose` 支持 Linux、macOS、Windows10 三大平台。 
+
+Linux 安装方式：
+
+```bash
+sudo curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
+sudo chmod +x /usr/local/bin/docker-compose
+```
+
+> :bell: 详情请参考：[Install Docker Compose](https://docs.docker.com/compose/install/)
+
+## 三、快速入门
+
+### web 应用
+
+新建文件夹，在该目录中编写 `app.py` 文件
+
+```python
+from flask import Flask
+from redis import Redis
+
+app = Flask(__name__)
+redis = Redis(host='redis', port=6379)
+
+@app.route('/')
+def hello():
+    count = redis.incr('hits')
+    return 'Hello World! 该页面已被访问 {} 次。\n'.format(count)
+
+if __name__ == "__main__":
+    app.run(host="0.0.0.0", debug=True)
+```
+
+### Dockerfile
+
+编写 `Dockerfile` 文件，内容为
+
+```docker
+FROM python:3.6-alpine
+ADD . /code
+WORKDIR /code
+RUN pip install redis flask
+CMD ["python", "app.py"]
+```
+
+### docker-compose.yml
+
+编写 `docker-compose.yml` 文件，这个是 Compose 使用的主模板文件。
+
+```yaml
+version: '3'
+services:
+
+  web:
+    build: .
+    ports:
+     - "5000:5000"
+
+  redis:
+    image: "redis:alpine"
+```
+
+### 运行 compose 项目
+
+```bash
+$ docker-compose up
+```
+
+此时访问本地 `5000` 端口，每次刷新页面，计数就会加 1。
+
+## 四、命令

+> - [Compose 命令说明中文文档](https://yeasy.gitbooks.io/docker_practice/content/compose/commands.html)
+
+## 五、模板文件
+
+> `docker-compose.yml` 文件是 Docker Compose 的模板文件，其作用类似于 Dockerfile 和 Docker。

+## 一、Dockerfile 简介
+
+Docker 镜像的定制实际上就是定制每一层所添加的配置、文件。如果我们可以把每一层修改、安装、构建、操作的命令都写入一个脚本，用这个脚本来构建、定制镜像，那么之前提及的无法重复的问题、镜像构建透明性的问题、体积的问题就都会解决。这个脚本就是 Dockerfile。
