Z2JH installation on k8s using helm chart

JupyterHub
1

Hi, I have setup k8s cluster with one control plane and three worker nodes, and installed helm and add JH repo to this chart which mentioned in Installing JupyterHub — Zero to JupyterHub with Kubernetes documentation and now when I am trying to install JH helm chart it’s taking too much time to install and finally throwing an message that “timed out waiting for the condition”.
When I checked the pod logs I am getting the below mentioned error

2024/01/04 13:04:59 [DEBUG] GET https://kubernetes.default.svc:443/apis/apps/v1/namespaces/default/daemonsets/hook-image-puller: retrying in 30s (1 left)

Hi @Pramod_Lomte

dial tcp: lookup kubernetes.default.svc on 10.96.0.10:53: read udp 192.168.193.70:52699->10.96.0.10:53: read: no route to host

From the log, the pods in the cluster can’t connect to one IP.

Thanks for the reply, but I am not able to understand how to resolve this, where to change and what to change.

the kube-scheduler,pause, in google_containers can not be downloaded in china, we always push this image in our own docker image repository to speed up downloads. maybe you can try this way
