在Heroku中从python应用程序运行Java子进程 [英] Running a java subprocess from a python app in Heroku

问题描述

我是Heroku的新手. flask Web应用程序的后端逻辑实际上正在运行Java子进程(subprocess.call( ...))以获取一些帮助程序数据. (我知道这是一件坏事)
部署后，Heroku可以按预期工作，并从Requirements.txt(而非JDK)安装Python运行时和框架.

I am new to Heroku. The backend logic of my flask web app is actually running a Java subprocess (subprocess.call( ...) ) to get some helper data. (I know it's a bad thing to do)
On deployment, Heroku works as expected and installs Python runtime and frameworks from requirements.txt but not JDK.

无论哪种方式，我都可以用相同的方式配置Java并使之工作?

Any way I can configure Java in the same and make this work ??

推荐答案

运行以下命令:

$ heroku buildpacks:add heroku/jvm

然后使用git push heroku master重新部署.这会将JDK安装到您的插件中.

Then redeploy with a git push heroku master. This will install the JDK into your slug.
