Hi there,
We have jupyterhub desployment over our Kubernetes infrastructure. We have different user profiles, one of these profiles is specially configured to run on a host with arm (and nvidia gpu):
- display_name: " environment with one NVIDIA"
description: "ARM, Edge, NVIDIA, GPU"
kubespawner_override:
image: step21/jupyter-minimal-notebook:arm64
extra_resource_guarantees:
nvidia.com/gpu: "1"
extra_resource_limits:
nvidia.com/gpu: "1"
node_affinity_required:
- matchExpressions:
- key: ARCH
operator: In
values:
- "arm64"
- matchExpressions:
- key: LAYER
operator: In
values:
- "edge"
start_timeout: 90
When I try to deploy a Server with this profile it finanlizes with a pod crash error. I have realized that in some moment, “something”, is trying to configure some iptables:
Going into that iptables container, I get:
# docker logs e43b920d5628
standard_init_linux.go:211: exec user process caused "exec format error"
Typical error produced by a docker image for a wrong architecture. But as you can see, the profile we try to deploy, uses an arm64 notebook.
The image used which runs the container with the exec error is: jupyterhub/k8s-network-tools. Which seems to have amd64 images but not arm64. What could we do?
