rootless docker: nvidia-device-plugin is failing with crashloopbackoff

What Happened?

I am trying to create a minikube cluster with nvidia GPU using docker driver. I have followed all the instructions mentioned into docs. On Using GPU with docker container directly it works as shown below

docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi

But when I try to create a minikube cluster with GPU support nvidia-device-plugin-daemonset pod is failing due to below error

failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: Auto-detected mode as 'legacy' nvidia-container-cli: mount error: failed to add device rules: unable to find any existing device filters attached to the cgroup: bpf_prog_query(BPF_CGROUP_DEVICE) failed: operation not permitted: unknown

Command I am using to create Cluster and output for the same

@ComradeProgrammer do you mind taking a look ?

medyagh commented 1 month ago

@nitishkumar71 I noticed you are using the rootless docker, do you mind trying with normal docker ? it might be that it is not supported for rootless

the "operation not permitted" error related to cgroups indicates a permissions problem. Docker needs access to manipulate cgroup settings for proper device management and isolation. this could be rootleess docker does not have permission to access that

additionally acording to our docs https://minikube.sigs.k8s.io/docs/drivers/docker/ it is recommended to try rootless docker with "containerd" --container-runtime flag to “containerd”.

so you if you have to use rootless, you might also wanna try it with containerd runtime instead

/triage needs-information /kind support

@medyagh Thanks for pointing it out. Running docker in root mode did worked. Since, GPU is only supported for docker container runtime only. Trying to use it with containerd gives proper error message.

I think use of root mode for docker should be highlighted in docs.. I can send a PR for it.

medyagh commented 1 month ago

thank you for confirming, we should have guard that if user has rootless docker they should not be able to enable gpu in first place or at least give them warmnining that this is not gonna work and they need Rooted Docker

NVIDIA runtime is known to work with Rootless Docker: https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html#rootless-mode

sudo nvidia-ctk config --set nvidia-container-cli.no-cgroups --in-place

Haven't tried with minikube though

kubernetes / minikube
