Tôi đã thực hiện câu trả lời khác để tạo giải pháp thuận tiện để tải các thuộc tính môi trường từ Cây đậu đàn hồi trực tiếp vào cấu hình ứng dụng ASP.NET Core của bạn.
Đối với ASP.NET Lõi 2.0 - chỉnh sửa Program.cs bạn
Lưu ý rằng WebHost build này được lấy từ mã nguồn của WebHostBuilder.CreateDefaultBuilder()

// TEMP CONFIG BUILDER TO GET THE VALUES IN THE ELASTIC BEANSTALK CONFIG
IConfigurationBuilder tempConfigBuilder = new ConfigurationBuilder();
tempConfigBuilder.AddJsonFile(

IConfigurationRoot tempConfig = tempConfigBuilder.Build();

}
Đối ASP.NET Core 1.0
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddJsonFile(@"C:\Program Files\Amazon\ElasticBeanstalk\config\containerconfiguration", optional: true, reloadOnChange: true)
.AddEnvironmentVariables();
var config = builder.Build();
builder.AddInMemoryCollection(GetEbConfig(config));
Configuration = builder.Build();
}
private static Dictionary<string, string> GetEbConfig(IConfiguration configuration)
{
Dictionary<string, string> dict = new Dictionary<string, string>();
foreach (IConfigurationSection pair in configuration.GetSection("iis:env").GetChildren())
{
string[] keypair = pair.Value.Split(new [] {'='}, 2);
dict.Add(keypair[0], keypair[1]);
}
return dict;
}
Dường như cùng một vấn đề khi triển khai ứng dụng .NET Standard sử dụng 'aws-windows-deployment-manifest.json': https://serverfault.com/questions/892493/windows-custom-elastic-beanstalk-deployment -missing-environment-variables – andrewf
