• [nitpick] The local variable 'DocumentDBContainer' should follow camelCase naming conventions (e.g., 'documentDbContainer').

var DocumentDBContainer = new DocumentDBServerResource(name, userName?.Resource, passwordParameter, tls, allowInsecureTls);

The value for 'Registry' does not match the remark comment ('ghcr.io/microsoft/documentdb') above. Please verify and update the registry URL to ensure consistency.

Suggested change

	public const string Registry = "ghcr.io/guanzhousongmicrosoft";
	public const string Registry = "ghcr.io/microsoft/documentdb";

Yes sorry for the confusion, I am working on the registry fix

Actually this should probably be hosted on mcr.microsoft.com right if its an officially built/signed image?
