-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | ## 如何用 Docker Compose 配置 Django 应用开发环境 2 | 3 | > 目标：搭建基于 Docker 的 Django 应用开发环境。 4 | > 5 | > 本项目代码维护在 **[DaoCloud/python-django-sample](https://github.com/DaoCloud/python-django-sample)** 项目中。 6 | > 7 | > 您可以在 GitHub 找到本项目并获取本文中所提到的所有代码文件。 8 | 9 | ### 前言 10 | 11 | 工欲善其事，必先利其器。这次我们将使用： 12 | 13 | * Docker >= 1.8.0 14 | * Docker Machine >= 0.4.1 15 | * Docker Compose >= 1.4.0 16 | 17 | 等工具，配置基于 Docker 的 Django 开发环境。 18 | 19 | #### Docker 20 | 21 | 一款轻量级容器管理引擎，由 Docker Daemon、Docker Client 组成。 22 | 23 | #### Docker Daemon 24 | 25 | Docker 架构中常驻后台的系统进程，负责接收处理用户发送的请求和管理所有的 Docker 容器，所谓的**运行 Docker** 即代表**运行 Docker Daemon**。 26 | 27 | #### Docker Client 28 | 29 | Docker 架构中用户与 Docker Daemon 建立通信的客户端。 30 | 31 | #### Docker Machine (!!deprecated) 32 | 33 | Docker 官方提供的部署工具。帮助用户快速在运行环境中创建虚拟机服务节点，在虚拟机中安装并配置 Docker，最终帮助用户配置 Docker Client，使得 Docker Client 有能力与虚拟机中的 Docker 建立通信。 34 | 35 | #### Docker Compose 36 | 37 | Docker 官方提供的容器编排工具。随着服务的复杂度增长，容器管理过程的配置项将变得冗长，Compose 可有效帮助用户缓解甚至解决容器部署的复杂性。 38 | 39 | #### 通过 Docker Machine 安装 Docker (!!deprecated) 40 | 41 | > 如果你是 Windows 或 OS X 用户推荐阅读以下章节，将指导您使用 Docker Machine 安装与管理 Docker。 42 | 43 | * 首先通过 `create` 命令创建一台名为 dev 的 VirtualBox 虚拟机，并已经安装好了 Docker。 44 | 45 | ```bash 46 | $ docker-machine create -d virtualbox dev; 47 | INFO[0000] Creating CA: /Users/dev/.docker/machine/certs/ca.pem 48 | INFO[0000] Creating client certificate: /Users/dev/.docker/machine/certs/cert.pem 49 | INFO[0001] Downloading boot2docker.iso to /Users/dev/.docker/machine/cache/boot2docker.iso... 50 | INFO[0035] Creating SSH key... 51 | INFO[0035] Creating VirtualBox VM... 52 | INFO[0043] Starting VirtualBox VM... 53 | INFO[0044] Waiting for VM to start... 54 | INFO[0094] "dev" has been created and is now the active machine. 55 | To point your Docker client at it, run this in your shell: $(docker-machine env dev) 56 | ``` 57 | 58 | > **提示** 59 | > 60 | > 由于 `create` 命令在初始化的时候，会从海外下载一个 ISO 镜像，由于国内网络不稳定，所以可能会在这一步耗费很长时间。 61 | > 62 | > 我们可以通过以下办法进行加速。 63 | > 64 | > OS X 65 | > 66 | > ```bash 67 | > $ mkdir ~/.boot2docker 68 | > $ echo ISOURL = \"https://get.daocloud.io/boot2docker/boot2docker-lastest.iso\" > ~/.boot2docker/profile 69 | > ``` 70 | > 71 | > Win 72 | > 73 | > ```bash 74 | > $ ISOURL = "https://get.daocloud.io/boot2docker/boot2docker-lastest.iso" 75 | > ``` 76 | 77 | * 设置环境变量以将本机的 Docker Client 和 dev 上的 Docker Daemon 建立通信。 78 | 79 | ```bash 80 | $ eval "$(docker-machine env dev)" 81 | ``` 82 | 83 | * 查看当前所有正在运行的 Machines 84 | 85 | ```bash 86 | $ docker-machine ls 87 | NAME ACTIVE DRIVER STATE URL 88 | dev * virtualbox Running tcp://192.168.99.100:2376 89 | 90 | ``` 91 | 92 | * 启动 Machine(dev) 93 | 94 | ```bash 95 | $ docker-machine start dev 96 | Starting VM ... 97 | ``` 98 | 99 | * 获取 Machine(dev) 的 IP 100 | 101 | ```bash 102 | $ docker-machine ip dev 103 | 192.168.99.100 104 | ``` 105 | 106 | * 通过 SSH 进入 Machine(dev) 107 | 108 | ```bash 109 | $ docker-machine ssh dev 110 | Starting VM ... 111 | ``` 112 | 113 | #### 通过 Docker Compose 编排应用 114 | 115 | > 因所有官方镜像均位于境外服务器，为了确保所有示例能正常运行，示例中使用与官方镜像保持同步的 DaoCloud 境内镜像： 116 | 117 | *docker-compose.yml* 118 | 119 | ```yaml 120 | web: 121 | build: . 122 | ports: 123 | - "8000:8000" 124 | links: 125 | - mysql:mysql 126 | - redis:redis 127 | env_file: .env 128 | command: /code/manage.py runserver 0.0.0.0:8000 129 | 130 | mysql: 131 | image: daocloud.io/mysql:latest 132 | environment: 133 | - MYSQL_DATABASE=django 134 | - MYSQL_ROOT_PASSWORD=mysql 135 | ports: 136 | - "3306:3306" 137 | 138 | redis: 139 | image: daocloud.io/redis:latest 140 | ports: 141 | - "6379:6379" 142 | ``` 143 | 144 | 在这个文件中。我们定义了 3 个 Docker 微服务 `web`、`mysql`、`redis`。 145 | 146 | - 通过 `build/image`，为微服务指定了 Docker 镜像 147 | - 通过 `links`，为 `web` 关联 `mysql` 与 `redis` 服务 148 | - 通过 `ports`，指定该服务需要公开的端口 149 | - 通过 `command`，指定该服务启动时执行的命令（可覆盖 Dockerfile 里的声明） 150 | 151 | 现在万事俱备，该让我们使应用运行起来啦，构建镜像并运行服务： 152 | 153 | ```bash 154 | $ docker-compose build 155 | $ docker-compose up -d 156 | ``` 157 | 158 | 别忘记要为项目初始化数据库哦： 159 | 160 | ```bash 161 | $ docker-compose run web /usr/local/bin/python manage.py migrate 162 | ``` 163 | 164 | 这样我们的 Demo 就可以通过浏览器来访问了 165 | 166 | **！！！**如果是使用 Docker Machine 的读者，您需要用 167 | 168 | ```bash 169 | $ docker-machine ip dev 170 | ``` 171 | 172 | 获取容器实际运行环境的 IP，并访问 `:8000`。 173 | 174 | 对于 Docker 安装在本地 Linux 机器上的读者，则直接使用 `127.0.0.1:8000` 即可。不出意外的话，您应该可以看到如下页面： 175 | 176 | ![](http://7xi8kv.com5.z0.glb.qiniucdn.com/python-django-sample-pic.png) 177 | 178 | #### 总结 179 | 180 | * Docker Machine 安装 Docker 181 | * Docker Compose 编排服务 182 | * 在开发状态下，容器只是单纯的运行环境 183 | * 通过 `docker-compose run service xxx` 执行 `xxx` 指令 184 | --------------------------------------------------------------------------------
