I’m running Jupyterhub on AWS EKS K8s cluster . the error “Spawn failed: Server didn’t respond in 120 seconds” occurs when logging in as a user.
note: we r using istio too
log user pod:
other testconnection from differnet pods:
What am I doing wrong?
That seems like maybe single user container not able to reach hub container. If you see in single user pod, there is a log
Updating hub with activity <snippet>. So, hub is waiting for the single user container to notify its activity and I assume it never got that notification and hence, hub assumed that single user container never started.
Could you do a
curl request from single user container to hub container to see if it is reachable? Maybe Istio blocking the communication?
Thanks a lot!!
I disabled the istio side-car, then works perfectly!
