var hostBuilder = new HostBuilder()    .ConfigureHostConfiguration((config) =>    {        config.AddEnvironmentVariables();    })    .ConfigureAppConfiguration((hostContext, config) =>    {        config.SetBasePath(Environment.CurrentDirectory);        config.AddJsonFile("appsettings.json", optional: false);        config.AddJsonFile($"appsettings.{hostContext.HostingEnvironment.EnvironmentName}.json", optional: true);        config.AddEnvironmentVariables();    });我在 Docker 文件中添加了新的全局環(huán)境變量ASPNETCORE_ENVIRONMENT = Development但我hostContext.HostingEnvironment.EnvironmentName總是Production如何使用默認(rèn)生產(chǎn)值覆蓋 Microsoft.Extensions.Hosting 中的 EnvironmentName？
