How can I use the image factory with docker to test out the extensions?

[wundersmiths]

Hello talos community! I want to do something like this:

• Create a customized image with a set of extensions from https://factory.talos.dev e.g. to test out longhorn locally
• Run it locally in docker e.g. using talosctl cluster create --workers 3 --image factory.talos.dev/nocloud-installer/376567988ad370138ad8b2698212367b8edcb69b5fd68c80be1f2ec7d603b4ba:v1.10.7

However, after the second step, it'll be stuck at waiting for API - looking at the container logs, I see

Usage:
  installer [command]


Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  install     

I suspect I'm missing something obvious here... Thanks!

Docker provisioner does not support extensions, you'd need to use qemu provisioner or a proper machine, since modules etc provided by extensions are signed and validated for the version of kernel that Talos ships

Thanks for the prompt response @frezbo! I'm using Windows and my understanding is the only way to use GPU in Linux is via WSL (at least unless you've two GPUs so you can pass one through) and running docker there is the simplest approach. Is there an alternative path to get it running on docker e.g. if host the image myself?

For my own understanding, can you clarify how this makes it incompatible with having a corresponding docker image?

docker uses the host kernel, the modules provided by talos are signed to be loaded by the kernel talos ships, so using docker will not work here
