+# Docker 支持
+
+## 使用 docker-compose 快速搭建开发环境（MySQL / Memcached）
+
+我们提供了 `dev-environment-setup.yml` 用于快速搭建开发环境。
+
+```shell script
+docker-compose -f ./docker-support/dev-environment-setup.yml up
+```
+
+运行这条命令后，可以快速搭建起以下环境：
+
+- MySQL 5.7 - 端口 `3306`，用户名 `root`，密码 `djangoblog_123`，自动以 UTF8MB4 编码创建 `djangoblog` 数据库
+- Memcached - 端口 `11211`
+
+## 构建镜像
+
+```shell script
+docker build -f .\docker-support\Dockerfile -t <你的 Docker Hub 用户名>/django_blog:latest .
+```
+
+## 运行自定义指令（例如数据库迁移）
+
+```shell script
+docker run -it --rm <你的 Docker Hub 用户名>/django_blog:latest <指令>
+```
+
+例如：
+
+```shell script
+docker run -it --rm -e DJANGO_MYSQL_HOST=192.168.231.50 django_blog/django_blog:latest makemigrations
+docker run -it --rm -e DJANGO_MYSQL_HOST=192.168.231.50 django_blog/django_blog:latest migrate
+docker run -it --rm -e DJANGO_MYSQL_HOST=192.168.231.50 django_blog/django_blog:latest createsuperuser
+```
