Hi, I am trying to follow the tutorial for setting up jupyterhub using minikube. However, after installing the helm chart, the hub pod gets a CrashLoopBackOff status.
After running describe, this is what I get:
Readiness probe failed: Get “http://10.244.205.200:8081/hub/health”: dial tcp 10.244.205.200:8081: connect: connection refused
And when I run kubectl logs, I got this;
[I 2024-05-25 10:24:04.883 JupyterHub app:2885] Running JupyterHub version 4.1.5

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) unable to open database file
(Background on this error at: https://sqlalche.me/e/20/e3q8)
I followed the instructions, and I left the config.yaml file as it’s shown in the tutorial (just some lines with comments). I am quite new to helm, so I don’t know if I’m missing something crucial
The minikube cluster is hosted on an AWS EC2 instance for which I increased the memory, so it could have enough.
