环境变量在Elastic Beanstalk Procfile中不可用

问题描述

我正尝试通过Procfile使用环境变量配置我的Elastic beantalk Java应用程序，如下所示:

I'm attempting to configure my elastic beanstalk java application using environment variables via the Procfile like so:

web: ./bin/myservice -Dhttp.port=$PORT

PORT环境变量是通过我的beantalk环境的软件配置"屏幕中的AWS ui设置的.

The PORT environment variable is set via the AWS ui in the "Software Configuration" screen of my beanstalk environment.

但是，日志表明未插入$PORT:

However, the logs are indicating that $PORT is not being interpolated:

Exception in thread "main" java.lang.ExceptionInInitializerError
    at com.whatever.services.myservice.Main.main(Main.scala)
Caused by: java.lang.NumberFormatException: For input string: "$PORT"
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
    at java.lang.Integer.parseInt(Integer.java:569)

将选项传递到我的应用程序的正确方法是什么?

What is the correct way to pass options to my application?

这似乎是与sbt本机打包程序插件有关的问题，我使用它来创建项目的可分发zip存档.它生成的bin/myservice文件从字面上解释$ PORT并将其传递给应用程序.

Edit 1: This seems to be an issue related to the sbt native packager plugin which I use to create a distributable zip archive of the project. The bin/myservice file it generates is interpreting $PORT literally and passing that to the application.

推荐答案

尝试从Procfile中删除-Dhttp.port=$PORT.

在ui的软件配置"中，尝试将变量JAVA_OPTS设置为-Dhttp.port=9000(将9000替换为您的nginx代理使用的任何端口-我相信默认值为5000.)

In the ui in "Software Configuration" try setting the variable JAVA_OPTS to -Dhttp.port=9000 (replace 9000 with whatever port your nginx proxy is using -- 5000 is the default I believe).
