I need to deploy JupyterHUB-K8s locally on minikube inside the intranet environment with no internet access. I can only download the files outside of this environment and get them inside the base image ubuntu 22.04.
I have docker installed but cant use docker hub to pull the images. However I can create docker file for a new build on the Ubuntu base image. What steps do I need to follow to package the whole jupyterHUB keeping all its dependencies locally downloaded? and what all dependent files do I need to download for this? I want to create a docker file to build a JupyterHUB image on Ubuntu base 22.04.
If you just want a way to transfer a container image offline you can use docker save and docker load:
If you want to build the hub image form scratch you’ll need to recursively download the dependencies. Start from the official Z2JH hub image:
The configurable-http-proxy image:
Thanks @manics Hub image is built with no issues.
Configurable-http-proxy is also getting built but failed during the vulnerability checks.
I tried putting this command “npm install tough-cookie@latest --save” to upgrade the tough-cookie to latest in the docker file. Somehow still getting the same error during vulnerability checks.
I am using ubuntu:22.04 as my base image
If you possibly can, going to jupyterhub-traefik-proxy will remove your runtime dependency on configurable-http-proxy, and very likely, nodejs, which is an overall win from a vulnerability-checking perspective.

I am getting an error while building a docker image with this repo “GitHub - jupyterhub/configurable-http-proxy: node-http-proxy plus a REST API”
Below is the error

Can anyone please help fixing this error?
When I built this proxy image on redhat/ubi8. I got the vulnerability fixed. However its not getting containerized on the kubernetes cluster. The error that I get in the pod is “env: ‘node\r’: No such file or directory”.
So I thought of building the image as it is as mentioned in “GitHub - jupyterhub/configurable-http-proxy: node-http-proxy plus a REST API”. But that is also failed.
