COMMON RESOLUTION

Error while adding migration: Unable to create an object of type 'OrderContext'

While creating migrations from Ordering.Infrastructure where it reads connecting string from appsettings.json which locates under Ordering.API it will throw the error saying Unable to create an object of type 'OrderContext'. To avoid this, for successful migrations we must pass --project and --startup-project arguments with ef migration command.

Here's the example below

dotnet ef migrations add initialMigration --project Ordering.Infrastructure --startup-project Ordering.API

Here 'startup-project' is project where connectionString settings are configured and 'project' is project directory where OrderContext is created. It will create migration folder under 'Ordering.Infrastructure'

NOTE: Microsoft.EntityFrameworkCore.Design is also required in .NET 6 for migrations. This should be installed under the project directory where OrderContext is created, in this case 'Ordering.Infrastructure'

Ocelot API Gw routing error in docker container

Docker is case sensitive environment. Handle any constant filename with sensitive operation.

If the filename is "Ocelot.Development.json" than rather using this line: $"ocelot.{builder.Environment.EnvironmentName}.json"

It should be like this with "O" in caps: $"Ocelot.{builder.Environment.EnvironmentName}.json"
