Docker 容器编排之 — compose 详解

• 我们知道使用一个 Dockerfile 模板文件可以定义一个单独的应用容器，如果需要定义多个容器就需要服务编排。服务编排有很多种技术方案，今天给大家介绍 Docker 官方产品 Docker-Compose。
• Dockerfile 可以定义一个单独的应用容器；而 docker-compose 则允许用户在一个模板（YAML 格式）中定义一组相关联的应用容器（被称为一个 project，即项目），例如一个 Web 服务容器再加上后端的数据库服务容器（LNMP）等。
• Docker-Compose 项目由 Python 编写，调用 Docker 服务提供的 API 来对容器进行管理。因此，只要所操作的平台支持 Docker API，就可以在其上利用 Compose 来进行编排管理。

• 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。
• Docker-Compose 将所管理的容器分为三层，分别是工程（project），服务（service）以及容器（container）。
• Docker-Compose 运行目录下的所有文件（docker-compose.yml，extends 文件或环境变量文件等）组成一个工程，若无特殊指定工程名即为当前目录名。一个工程当中可包含多个服务，每个服务中定义了容器运行的镜像、参数、依赖。一个服务当中可包括多个容器实例。
• Docker-Compose 并没有解决负载均衡的问题，因此需要借助其他工具实现服务发现及负载均衡，比如 Consul。

• Docker-Compose 的工程配置文件默认为 docker-compose.yml，可通过环境变量 COMPOSE_FILE 或 -f 参数自定义配置文件，其定义了多个有依赖关系的服务及每个服务运行的容器。

YAML 是一种标记语言，它可以很直观的展示数据序列化格式，可读性高。类似于 SML 数据描述语言，语法比 XMA 简单很多。YAML 数据结构通过缩进来表示，连续的项目通过符号 - 来表示，键值对用符号 : 分割，数组用中括号 [ ] 括起来，hash 用花括号 {} 括起来。

1.对象：键值对的字典

• animal: pets

2.数组：一组按次序排列的结果

• CAT
• DOG
• GOLDFISH

3.布尔值

• debug: true
• debug: false

示例：

Docker-Compose 是 Docker 的独立产品，因此需要安装 Docker 之后再单独安装 Docker-Compose
