Asp net core EF Ошибка при создании миграции

При попытке создать миграцию пишет: Build started... Build succeeded. An error occurred while accessing the Microsoft.Extensions.Hosting services. Continuing without the application service provider. Error: Этот хост неизвестен. Unable to create an object of type 'AppDbContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728 Process terminated with exit code 1.

DbContext:

    public DbSet<User> Users { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.ApplyConfiguration(new UserConfiguration());
        base.OnModelCreating(modelBuilder);

}

файл docker:

FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
WORKDIR /src
COPY ["COMPOSETEST/COMPOSETEST.csproj", "COMPOSETEST/"]
RUN dotnet restore "COMPOSETEST/COMPOSETEST.csproj"
COPY . .
WORKDIR "/src/COMPOSETEST"
RUN dotnet build "COMPOSETEST.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "COMPOSETEST.csproj" -c Release -o /app/publish /p:UseAppHost=false

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "COMPOSETEST.dll"]

вот файл appsetings.json:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "DB": "Server=postgres_db;port=5432;User id=postgres;password=123;database=DB"
  }
}

вот подключение к бд:

var connectionString = builder.Configuration.GetConnectionString("DB");

builder.Services.AddDbContext<AppDbContext>(options =>
{
    options.UseNpgsql(connectionString);
});

база данных Postgres контейнеры запускаются без ошибок
