Is there any way to see a list of images within my k3d registry?

I am asking the same question. One can dig through the docker volumes, but a listing of images seems an awfully useful (but missing) feature.

Discussed in #1407

I'm getting started with k3d and learning how things work. So far, k3d registries feel like black boxes with no visibility to what's inside. After pushing an image to a k3d registry, I haven't found a way to verify that the image is in there.

My use case is a kubernetes cluster in a development environment. I'm using Skaffold and helm to automatically build and push images to a k3d registry, but I'm running into errors.

Cleaning up...
release "web" uninstalled
1/1 deployment(s) failed

It looks like an image from my k3d registry can't be pulled. My initial thought for troubleshooting is to look inside the k3d registry to see if the image with that name is actually in there. However, I don't know of a way to look inside the k3d registry.

The only k3d registry commands I see in the docs are create, delete, and, list. List seems like it could be helpful, but all it does is display the registry name, not it's image contents.

Are there any recommended approaches for this situation?
