I was afraid to hear that. I just don’t want to spend too much time on learning FCOS because I clearly see that CAPI is the best way forward.

My approach to get NVIDIA driver working in FCOS is quite simple.

I deploy NVIDIA gpu Operator using Helm without driver:

I add a new node group to my existing K8s cluster with one worker node e.g latest FCOS image and a flavor that has a GPU.

Next I assign a Floating IP to the new worker node and ssh to it.

Then I just follow the steps to install the rpmfusion.org repo, reboot and then install the driver.

After that I take an image of the worker node:

OpenStack server image create

And then I try to deploy a node group using this new image but it just doesn’t work. I already checked the worker heat logs but could find any clue why the node is no joining the cluster. To be honest, I can’t even remember if heat actually deploys the new worker node using the modified image. Seems there is some mechanism in FCOS that can only run once and I would need to test this. Or maybe I’m completely off track and need to use the assembler.

I’m currently also looking into getting the gpu Operator working with a working NVIDIA driver container. I made some good progress yesterday. To me it seems that the existing code just needs some fixing for the download links for the rpm’s.

Cheers,
