HI All,

I created a custom image with dockerfile below : and deployed through helm Jupyterhub config file.

1. Config file below:

> > >

proxy:  
secretToken:

 

singleuser:  
defaultUrl: “/lab”  
profileList:  
- display\_name: “Data Science Spark environment”  
description: “Data Science libraries with the spark”

1. Created k8s ingress record to pointing to hub service.

2. When I am logging in – I am getting this redirect error:

 

![image](https://canada1.discourse-cdn.com/flex031/uploads/jupyter/original/2X/c/c63c8539317052923676562385cbe3aec86bb072.png)

 
1. Logs mention below for ssikarwa user:

 
# 500 : Internal Server Error

Redirect loop detected. Notebook has jupyterhub version 0.9.1, but the Hub expects 1.2.2. Try installing jupyterhub==1.2.2 in the user environment if you continue to have problems.

Any support will be highly appreciated.

Have you tried the suggestion from the error message? `jupyter/all-spark-notebook:2343e33dec46` is a very old image, can you use a more recent one?

Thanks for the reply @manics : Mistake was mine – I was connecting by ingress to hub service instead of proxy-public.

It worked after that.
