- [X] Fill out repository and branch below
- [X] Set up CodeForPhilly.org project profile and add link below
- [X] Record any additional notes, if any

## Deployment specifications

- **Repository:** https://github.com/phlask/phlask-map

## Additional notes

从 dockerize 分支上的 phlask-map 仓库开始，并验证现有的 `docker-compose up` 设置。该 issue 没有明确部署环境、部署文件，也没有明确说明除部署应用程序之外的具体完成检查，因此请在开始之前明确这些要求。
