Summary
I am adding a node to the Kubernetes cluster as a node using flannel. Here are the nodes on my cluster:
kubectl get nodes
NAME STATUS ROLES AGE VERSION
jetson-80 NotReady <none> 167m v1.15.0
p4 Ready master 18d v1.15.0
This machine is reachable through the same network. When joining the cluster, Kubernetes pulls some images, among others k8s.gcr.io/pause:3.1, but for some reason failed in pulling the images:
Warning FailedCreatePodSandBox 15d
kubelet,jetson-81 Failed create pod sandbox: rpc error: code = Unknown desc = failed pulling image "k8s.gcr.io/pause:3.1": Error response from daemon: Get https://k8s.gcr.io/v2/: read tcp 192.168.8.81:58820->108.177.126.82:443: read: connection reset by peer
The machine is connected to the internet but only wget command works, not ping
How I tried to solve it
I tried to pull images elsewhere and copy them to the machine.

Here are the list of pods on the master :

but it didn’t work either when I check the associated flannel pod kube-flannel-ds-arm64-4s7kk:

I still can’t identify if it’s a Kubernetes or Flannel issue and haven’t been able to solve it despite multiple attempts. Please let me know if you need me to share more details
