Error creating and seeding database using Docker

When I run this code with IIS it is working, but if I am using Docker I get the below error. Could anybody help me solve this issue?

public static void Main(string[] args)
{
    var host = CreateHostBuilder(args).Build();

    //Seed database
    using (var scope = host.Services.CreateScope())
    {
        var services = scope.ServiceProvider;

        try
        {
            var databaseInitializer = services.GetRequiredService<IDatabaseInitializer>();
            databaseInitializer.SeedAsync().Wait();
        }
        catch (Exception ex)
        {
            var logger = services.GetRequiredService<ILogger<Program>>();
            logger.LogCritical(LoggingEvents.INIT_DATABASE, ex, LoggingEvents.INIT_DATABASE.Name);

            throw new Exception(LoggingEvents.INIT_DATABASE.Name, ex);
        }
    }

    host.Run();
}
