@tnc1997's container not support TLS and his module uses the insecure port of that container.

As had been previously discussed,

ConfigurationClient refuses to connect to a URI endpoint over an unsecured HTTP connection.

The Azure SDK (and specifically ConfigurationClient) enforce TLS everywhere.

The official CosmosDB emulator offers an endpoint for fetching the PEM certificate to make this requirement a little easier to deal with, however there are more issues in play such as the app config domain and scope/identity requirements which had also been discussed extensively.

I worked very hard to [address these issues in my Testcontainers module](https://github.com/goldsam/azure-app-configuration-emulator/blob/9adc28f418b7ae9030c90f859f77fa137aa46311/src/AzureAppConfigurationEmulator.Test containers/AzureAppConfigurationEmulatorBuilder.cs#L71-L91), and was quite disappointed that you discarded that work.

@tnc1997 I had spent a LOT of time contributing to your project throughout our discussions addressing these matters, so this feels like a bit of a slap in the face.

Hi @goldsam, I appreciate your concerns.

Firstly, the Azure SDK does not enforce TLS everywhere, for example the storage clients to name a few:

• https://github.com/testcontainers/testcontainers-dotnet/blob/develop/src/Testcontainers.Azurite/AzuriteContainer.cs#L30-L32
• https://github.com/testcontainers/testcontainers-dotnet/blob/develop/tests/Testcontainers.Azurite.Tests/AzuriteContainerTest.cs

Secondly, a test has been added that shows that the ConfigurationClient works fine without TLS:

• https://github.com/tnc1997/testcontainers-dotnet/blob/feat/1198/tests/Testcontainers.AzureAppConfiguration.Tests/AzureAppConfigurationContainerTest.cs

Connecting to the emulator using HMAC authentication is the recommended approach, hence the GetConnectionString convenience method which aligns with other Testcontainer modules in this repository such as Azurite. Extending the out-of-the-box container that is returned to align with custom requirements is very easy due to the ContainerBuilder interface:

.crt & .key

var container = new AzureAppConfigurationBuilder()
    .WithEnvironment("ASPNETCORE_HTTP_PORTS", "8080")
    .WithEnvironment("ASPNETCORE_HTTPS_PORTS", "8081")
    .WithEnvironment("Kestrel__Certificates__Default__Path", "/usr/local/share/azureappconfigurationemulator/emulator.crt")
    .WithEnvironment("Kestrel__Certificates__Default__KeyPath", "/usr/local/share/azureappconfigurationemulator/emulator.key")
    .WithResourceMapping("emulator.crt", "/usr/local/share/azureappconfigurationemulator/emulator.crt")
    .WithResourceMapping("emulator.key", "/usr/local/share/azureappconfigurationemulator/emulator.key")
    .Build();

.pfx

var container = new AzureAppConfigurationBuilder()
    .WithEnvironment("ASPNETCORE_HTTP_PORTS", "8080")
    .WithEnvironment("ASPNETCORE_HTTPS_PORTS", "8081")
    .WithEnvironment("Kestrel__Certificates__Default__Password", "password")
    .WithEnvironment("Kestrel__Certificates__Default__Path", "/root/.aspnet/https/aspnetapp.pfx")
    .WithResourceMapping("aspnetapp.pfx", "/root/.aspnet/https/aspnetapp.pfx")
    .Build();
