I got a K8S+DinD issue:
could not select device driver "nvidia" with capabilities: [[gpu]]Full error
http://localhost:2375/v1.40/containers/long-hash-string/start: Internal Server Error ("could not select device driver "nvidia" with capabilities: [[gpu]]")
exec to the DinD image inside of K8S pod, nvidia-smi is not available.
Some debugging and it seems it's due to the DinD is missing the Nvidia-docker-toolkit, I had the same error when I ran the same job directly on my local laptop docker, I fixed the same error by installing nvidia-docker2 sudo apt-get install -y nvidia-docker2.
I'm thinking maybe I can try to install nvidia-docker2 to the DinD 19.03 (docker:19.03-dind), but not sure how to do it? By multiple stage docker build?
Thank you very much!
update:
pod spec:
spec:
containers:
- name: dind-daemon
image: docker:19.03-dind
I got it working myself.
Referring to
First, I modified the ubuntu-dind image (https://github.com/billyteves/ubuntu-dind) to install nvidia-docker (i.e. added the instructions in the nvidia-docker site to the Dockerfile) and changed it to be based on nvidia/cuda:9.2-runtime-ubuntu16.04.
Then I created a pod with two containers, a frontend ubuntu container and the a privileged docker daemon container as a sidecar. The sidecar's image is the modified one I mentioned above.
But since this post is 3 year ago from now, I did spent quite some time to match up the dependencies versions, repo migration over 3 years, etc.
My modified version of Dockerfile to build it

When I use exec to login into the Docker-in-Docker container, I can successfully run nvidia-smi (which previously return not found error then cannot run any GPU resource related docker run)
