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 follo

Answer 1

.NET Core 2 + posrgresql RDS

Further to @sebastian's great answer above, I found that the settings were in a different part of the file, viz. plugins:rds:env.

Also there was no need to split on =, so the parsing code I have is:

private static void SetEbConfig()
        {
            var tempConfigBuilder = new ConfigurationBuilder();

            tempConfigBuilder.AddJsonFile(
                @"C:\Program Files\Amazon\ElasticBeanstalk\config\containerconfiguration",
                optional: true,
                reloadOnChange: true
            );

            var configuration = tempConfigBuilder.Build();

            var ebEnv = configuration.GetSection("plugins:rds:env")
                                        .GetChildren()
                                        .ToDictionary(child => child.Key, child => child.Value);

            foreach (var keyVal in ebEnv)
            {
                Environment.SetEnvironmentVariable(keyVal.Key, keyVal.Value);
            }
        }

The relevant (and redacted ;-)) JSON is as follows:

{
    "plugins": {
        "rds": {
            "Description": "RDS Environment variables",
            "env": {
                "RDS_PORT": "....",
                "RDS_HOSTNAME": "....",
                "RDS_USERNAME": "....",
                "RDS_DB_NAME": "....",
                "RDS_PASSWORD": "...."
            }
        }
    }
}
