使用 nodeJs/Adonis 在 heroku 上部署：我收到 503 状态 - 服务不可用
Deploy on heroku with nodeJs/Adonis: I'm getting 503 Status - Service Unvailable
我正在尝试使用 heroku 进行部署，但是当我进入 URL/route 时，我得到：
Status: 503 Service Unvailable.
我的申请只有api;
我的 ProcFile：
release: ENV_SILENT=true node ace migration:run --force
网络：ENV_SILENT=true npm start
当我 运行 git push heroku master 我得到：
Enumerating objects: 5, done. Counting objects: 100% (5/5), done.

我尝试在 localhost 中工作的不同路由，但是当我在 heroku 中尝试时，我得到 503。

答案：尝试将HOST更改为0.0.0.0（在您的Heroku环境变量中）
