如何创建 play heroku procfile? [英] How to create play heroku procfile?

问题描述

我按照这里的指示

http://blog.heroku.com/archives/2011/8/29/play/

但我做了play run然后git push heroku master但是没有找到procfile.

but I do play run and then git push heroku master but a procfile is not found.

-----> No Procfile found. Will use process: 
       play run --http.port=$PORT $PLAY_OPTS

1. 如何显式创建 procfile?
2. 说明似乎表明我应该在应用程序运行时推送到 heroku master.我读错了吗?
3. 在哪里可以为 mydomain.herokuapp.com 指定 $PORT 和 $PLAY_OPTS?
4. 是否只修改 application.conf 中 %prod 的值更好?

1. How do I explicitly create a procfile?
2. The instructions seem to indicate that I should push to heroku master while the app is running. Am I reading that wrong?
3. Where can I specify $PORT and $PLAY_OPTS for mydomain.herokuapp.com?
4. Is it better to just modify the values for %prod in application.conf?

推荐答案

您需要在项目的根目录中创建一个名为 Procfile 的文件，并且对于 Play，它应该包含

You need to create a file named Procfile in the root of your project and for Play it should contain

web: play run --http.port=$PORT $PLAY_OPTS

然后部署应用程序时，$PORT 和 $PLAY_OPTS 将在应用程序启动时由 heroku 设置.

When you then deploy your application the $PORT and $PLAY_OPTS will be set by heroku when the application is started.
