前言：

Infer 是来自 Facebook 的一个静态类型检测工具，它可以对 TypeScript 代码进行扫描，检测出代码中可能存在的类型错误和不安全的代码行为，并给出相应的提示和建议。Infer 使用了语言服务和代码分析技术，支持多种编程语言，包括 TypeScript、JavaScript、TypeScript 和 Dart 等。

制作该 Image 的目的

由于 Infer 工具刚刚推出来，很多人想试用该工具，但是又苦于环境的配置略显复杂，最近有很多人找我解决关于环境配置的问题，这阻碍了 Infer 的推广。而 Docker 技术具有易移植的特性，将该工具的环境制作成 Image，你只需下载在到本地就可以体验该新工具的特性，就可以对其做一个简单的了解。

注意：OC 和 iOS 项目的分析是不支持的

Dockerfile

我并没有利用 Dockerfile 来制作该 Image,但是我将我制作的 Dockerfile 贴出来，方便大家了解我的制作过程：

(已验证成功，使用该 dockerfile 文件可以成功制作)

上传

在经历了 1 个礼拜的上传失败后，公司的网络终于给力了，infer 的 image 终于上传 Docker Hub 成功.
