Please add the module label, I'm not sure how to do that

Thanks for creating the issue. Do you know if any changes to the module are necessary? Could you simply override the default image instead? Typically, we try to avoid changing the default image version to prevent introducing breaking changes; instead, we recommend developers to pin the version.

[keshramjith]

Yes, I did try overriding the image with .WithImage(), however I encountered a bunch of issues and some module changes are required.

[HofmeisterAn]

I see, thanks for the clarification. In this case, we usually make the necessary changes but try to support both configurations and ensure backward compatibility.
