How to properly change Java Runtime on Dokku app container?
问题
我正在服务器上的Dokku容器内运行Ktor后端应用程序。默认情况下似乎使用的是Java 8。我应该如何正确地将Dokku容器上的Java运行时更改为Java 11？
我不确定是否应该进入Dokku应用程序容器并更新Java，还是在Dokku或我的Ktor项目中是否有可用的配置，或者是否还有其他方法。
英文:
I'm running a Ktor backend app inside of a Dokku container on a server. It seems that by default Java8 is used. How can I properly change Java Runtime on dokku container to be Java 11?
I'm not sure if I should enter the dokku app container and update the Java, or is there some configuration available that I can use either on the dokku or my Ktor project side, or something else.

If deploying via the official Heroku buildpack for Java, you can specify a java.runtime.version in your system.properties as documented here.
