Installation times out when installing JupyterHub on kubernetes (OKD)

I am trying to install JupterHub on kubernetes (OKD) by following this guide http://z2jh.jupyter.org/

I run following commands:

[root@master-01 jhub]# helm repo add jupyterhub https://jupyterhub.github.io/helm-chart/
“jupyterhub” has been added to your repositories
[root@master-01 jhub]# helm repo update
Hang tight while we grab the latest from your chart repositories…
…Skip local chart repository
…Successfully got an update from the “jupyterhub” chart repository
…Successfully got an update from the “stable” chart repository
Update Complete.
[root@master-01 jhub]# RELEASE=jhub
[root@master-01 jhub]# NAMESPACE=jhub[root@master-01 jhub]# helm upgrade --install $RELEASE jupyterhub/jupyterhub --namespace $NAMESPACE --version=0.9.1 --values config.yaml
Release “jhub” does not exist. Installing it now.
Error: timed out waiting for the condition

I have set the time out to 1 hour, still same outcome. It seems to hang. It creates the pods below and that is it.

kubectl --namespace=jhub get pod
NAME READY STATUS RESTARTS AGE
hook-image-awaiter-hnzng 1/1 Running 0 2m
hook-image-puller-4bkb4 1/1 Running 0 2m
hook-image-puller-lgnr4 1/1 Running 0 2m
hook-image-puller-rfnv2 1/1 Running 0 2m
hook-image-puller-rh4xg 1/1 Running 0 2m

[root@master-01 jhub]# cat config.yaml
proxy:
secretToken: “f77fd3605c36991e4d0e870caad9f00da181dd7293cf78bee2b713c6473d9c5c”
hub:
uid: 0
fsGid: 0

[root@master-02 ~]# kubectl logs hook-image-awaiter-hnzng -n jhub
2020/07/20 09:33:45 4 of 10 nodes currently has the required images.

It keeps output the line above in the log till the installation times out.

logs empty for the other 4 pods.

Any help much appreciated!

Thanks
