Can not pass (or read) environment variables from docker + .net core

.Net core 5.0.103

docker version: 20.10.2, build 2291f61 (Ubuntu)

I create docker image + try to get environment variables from command line. So:

docker run -it --rm robust_tapir -e ADDRESS='127.0.0.1' -e Port='5000' -e Schema='http'

And result is:

[15:08:57 ERR] Hello World!
[15:08:57 ERR] Address:
[15:08:57 ERR] Port:
[15:08:57 ERR] Schema:

In my .net core console app:

            Logger = CreateLogger();
            Logger.Error("Hello World!");

            await Task.Delay(5);

            Address = Environment.GetEnvironmentVariable("ADDRESS");
            Port = Environment.GetEnvironmentVariable("Port");
            Schema = Environment.GetEnvironmentVariable("Schema");
       
#if DEBUG
            Address = "127.0.0.1";
            Port = "5000";
            Schema = "http";
#endif
            Logger.Error($"{nameof(Address)}:{Address}");
            Logger.Error($"{nameof(Port)}:{Port}");
            Logger.Error($"{nameof(Schema)}:{Schema}");

            while (string.IsNullOrEmpty(Address))
            {
                await Task.Delay(1000);
            }

So, what i do wrong? Wrong pass into container or wrong read it from .net core?

Quotes goes around the entire env. argument:

docker run -it --rm robust_tapir -e "ADDRESS=127.0.0.1" -e "Port=5000" -e "Schema=http"
