Publish ASP 5 application to Azure in a custom environment

Question

In my ASP.NET 5 (core, vNext) application I have:

appsettings.test.json
appsettings.development.json
appsettings.staging.json
appsettings.production.json
appsetings.cloud.json

Each of these include different connection strings (for different environments).

Problem

When I publish my application to Azure, it automatically uses the Production environment.

I want to use the Cloud environment, when I publish to Azure.

Note

I am using the one month free trial of Azure, which wont allow me to create deployment slots (I need to upgrade).

Question

So, is there anyways I can publish to Azure in my custom environment (Cloud) by default?

Yes.

The easiest way is the Azure portal. Go to MyWebApp > Settings > Application Settings > App settings. Set the ASPNET_ENV variable to Cloud.

We can test this with a simple ASP.NET Core application.

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json");

        builder.Build();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        app.Run(async (context) =>
        {
            await context.Response
                .WriteAsync("Hello from " + env.EnvironmentName);
        });
    }
}

It works as expected.
