将管理/管理任务作为JVM中的一次性进程运行（12因子应用程序）

Question

有人可以提供一个运行管理/管理任务作为一次性流程的例子（如12因素应用宣言的第12个因素中提出的那样），请记住它将在依赖于Gradle buildpack的JVM应用程序的上下文中在Heroku上运行？

Answer 1

It's quite easy.

In your codebase, build a script that can be run using some command-line invocation.

For instance:

java myscript

Once you've verified this works locally, push your code to Heroku, open up the scheduler addon via $ heroku addons:open scheduler , then define how often you want the task to run, and in the command box put in your command to run it: java myscript

All Heroku will do is run a dyno and run that command you specify. Super basic!
