Greetings @anthonyabboud,
I believe the issue here is more or less what is described in this comment here: Pre-provisioned image from local docker - #6 by jeremias.tx
Basically for the --dind-param you need to pass the IP address of the container that is running the local registry. Not the IP address of your laptop itself. Though you’ll also need to push your container image to the registry with the name pattern <registry container IP address>:5000/my-custom-image.
Best Regards,
Jeremias
