AWS弹性beanstalk环境在asp.net core 1.0中 [英] AWS elastic beanstalk environment in asp.net core 1.0

问题描述

如何从弹性beanstalk中获取环境变量到asp.net核心mvc应用程序？我已经添加了一个包含app.config文件的.ebextensions文件夹，其中包含以下内容：

  option_settings：
  -  option_name ：HelloWorld 
值：占位符
 
  -  option_name：ASPNETCORE_ENVIRONMENT 
值：占位符
  

.ebextensions文件夹包含在发布包中。

部署时，这两个变量在aws elasticbeanstalk控制台中可见，配置>软件配置>环境变量

但是，当我尝试读取应用程序中的变量时，以下选项都不工作：

  Environment.GetEnvironmentVariable（HelloWorld）//在控制器
配置[HelloWorld] //在startup.cs 
  

有什么可以丢失的想法？谢谢。

解决方案

有同样的问题，刚收到AWS支持有关此问题的回复。显然，环境变量在弹性beanstalk中没有适当地注入到ASP.NET Core应用程序中。

据我所知，他们正在努力解决问题。

解决方法是解析 C：\Program Files\Amazon\ElasticBeanstalk\config\containerconfiguration 进入配置构建器。这个文件是弹性beanstalk环境的一部分，应该在部署项目时可以访问。

首先添加文件：

$ {code> var builder = new ConfigurationBuilder（）
.SetBasePath（C：\\Program Files\\Amazon\\\ElasticBeanstalk\\config ）
.AddJsonFile（containerconfiguration，可选：true，reloadOnChange：true）;

然后访问值：

  var env = Configuration.GetSection（iis：env）。GetChildren（）; 
 
 foreach（envKeyValue in env）
 {
 var splitKeyValue = envKeyValue.Value.Split（'='）; 
 var envKey = splitKeyValue [0]; 
 var envValue = splitKeyValue [1]; 
 if（envKey ==HelloWorld）
 {
 // use envValue here 
} 
}

How do I get environment variables from elastic beanstalk into an asp.net core mvc application? I have added a .ebextensions folder with app.config file in it with the following:
option_settings:
- option_name: HelloWorld
  value: placeholder

- option_name: ASPNETCORE_ENVIRONMENT
  value: placeholder
The .ebextensions folder is included in the publish package.

On deployment, both the variables are visible in the aws elasticbeanstalk console at Configuration > Software Configuration > Environment Variables

However, when I try to read the variables in the application, none of the below options are working:
Environment.GetEnvironmentVariable("HelloWorld") // In controller
Configuration["HelloWorld"] // In startup.cs
Any ideas on what I could be missing? Thanks.
解决方案
Had the same problem, and just received a reply from AWS support about this issue. Apparently environment variables are not properly injected into ASP.NET Core applications in elastic beanstalk. 

As far as I know, they're working to fix the problem.

The workaround is to parse C:\Program Files\Amazon\ElasticBeanstalk\config\containerconfiguration into the configuration builder. This file is part of your elastic beanstalk environment and should be accessible upon deploying your project.

First add the file:
var builder = new ConfigurationBuilder()
    .SetBasePath("C:\\Program Files\\Amazon\\ElasticBeanstalk\\config")
    .AddJsonFile("containerconfiguration", optional: true, reloadOnChange: true);
Then access the values:
var env = Configuration.GetSection("iis:env").GetChildren();

foreach (var envKeyValue in env)
{
    var splitKeyValue = envKeyValue.Value.Split('=');
    var envKey = splitKeyValue[0];
    var envValue = splitKeyValue[1];
    if (envKey == "HelloWorld")
    {
        // use envValue here
    }
}
