使用 Docker 为开发安装 Discourse

[hawm]

嗨，我想我们应该在这里添加一段关于 Ember-CLI 的描述，并为下方的命令提供一个快捷方式，这样就不需要进入 Docker 容器了。

而且，我在容器内执行上述命令时无法使其正常工作，似乎容器没有暴露 4200 端口。

通过编辑 d/boot_dev 手动暴露 4200 端口：

重启容器后，我访问 localhost:4200 却得到了这个结果：

discourse@discourse:/tmp$ cat error.dump.cab4cc444229d44fc0fce2deb8695880.log

将 bin/ember-cli 中的 PORT 从 3000 改为 9292 后，一切正常了。

看起来 ember-cli 的 bash 脚本无法与 ENV["UNICORN_PORT"] 协同工作。
