Is `wandb launch -d` or `wandb job create image` uploading a whole Docker artifact and not pulling from a registry?

No, the wandb launch -d command doesn’t upload images to a registry. Upload images to a registry separately. Follow these steps:

Build an image.
Push the image to a registry.

The workflow is as follows. Replace [REPO-URL] with your registry URL and [TAG] with the image tag:

docker build -t [REPO-URL]:[TAG] .
docker push [REPO-URL]:[TAG]
wandb launch -d [REPO-URL]:[TAG]

The launch agent then starts a job pointing to the specified container. For examples of configuring agent access to pull images from a container registry, see Advanced agent setup. For Kubernetes, ensure that the Pods in the cluster have access to the registry where the image is pushed.
