How to set the environment in a docker with Visual Studio 2019 in ASP.NET Core 3.1?

struggling in Visual Studio 2019 in ASP.NET Core 3.1 (Win10 with Docker Desktop). I only want to change the "ASPNETCORE_ENVIRONMENT" from "Development" to "Production.

So what I've done was then to edit launchSettings.json

and edit the environment variables section:

"profiles": {

   ///cut other

   "Docker": {
        "commandName": "Docker",
        "launchBrowser": true,
        "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}/version",
        "environmentVariables": {
           "ASPNETCORE_ENVIRONMENT": "Production",
           },

        "publishAllPorts": true,
        "useSSL": false
   }
 }

When I then start debugging in Visual Studio I get: "Unable to configure HTTPS endpoint", unless it is working fine with "Development". Nevertheless the container shows in docker inspect still the "Development"

enter image description here

When I then add "ASPNETCORE_URLS": "http://+:80" the container starts but still shows ASPNETCORE_ENVIRONMENT = Development. Also inside the docker when executing "ENV".

Don't really know, what else I can try.

Hope on your guidance.

Thanks in advance.

Maybe it is a UI Bug, you can check by

Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");

In my case, the application shows "Production", but Visual Studio container debug tool shows "Developement".

Besides, you can add a "appsetting.Production.json" to double check the config is changing to Production, hope it helps.

You can find this question helpful: ASPNETCORE_ENVIRONMENT in Docker

The proposed solution there - specify the environment in Dockerfile`s ENTRYPOINT: ENTRYPOINT ["dotnet", "CoreDocker.dll", "--environment=Production"]
