当在宿主机启动较多的容器时候如果都是手动操作会觉得比较麻烦而且容易出错 并且每个容器之间也会有先后启动的顺序依赖等。这个时候推荐使用 docker 单机 编排工具 docker-composedocker-compose 是 docker 容器的一种单机编排服务 docker-compose 是一个管理多个容器的工具比如可以解决容器之间的依赖关系 就像启动一个 nginx 前端服务的时候会调用后端的 tomcat那就得先启动 tomcat 但是启动 tomcat 容器还需要依赖数据库那就还得先启动数据库docker-compose 就可以解决这样的嵌套依赖关系其完全可以替代 docker run 对容器进行创建、启动 和停止。
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)及容器(container)。
docker-compose 是一个用于定义和运行多个容器 Docker 应用程序的工具。使用 Compose可以使用 YAML 文件来配置应用程序的服务。然后使用一个命令从 配置中创建并启动所有服务。所以在使用 docker-compose 时编写比较规范的.yaml 或则.yml 文件是比较重要的。Compose 文件就是一个 YAML 文件用其来定义 服务、网络和数据卷等。docker-compose 默认会在当前目录找该文件即 ./docker-compose.yml。

1.1 安装 python-pip 包管理器
在 linux 平台安装python-pip 包会安装 pip 命令pip 命令是一个 pyhton 安装包的安装管理工具其类似于 ubuntu 的 apt 或者 redhat 的 yum但是 pip 只安装 python 相关的安装包。pip 工具可以在多种 操作系统安装和使用。

二. 使用 docker-compose 启动单个容器
编写 yaml 格式的 compose 文件时可以在任意目录新建.yaml文件并从 该目录启动容器。
2.1 编写构建单个容器的 compose 文件
编写 yml 格式的 docker-compose 文件启动一个 nginx 服务yaml 文档 的语法严格要求上下各行缩进的关系。
rootubuntu-suosuoli-node1:~# mkdir /data/compose
rootubuntu-suosuoli-node1:~# cd /data/compose
rootubuntu-suosuoli-node1:/data/compose# vim docker-compose.yamlservice-nginx:image: nginx:compiled_V1expose:- 80- 443ports:- 80:80- 443:4432.2 启动容器
在 docker compose 文件所在的目录执行docker-compose up -d 不加-d选项表示前台启动容器。
