TimeourError after spawning container

[MarcoMeter]

This issue might be related to #55

Hello everybody,

I basically followed your instructions, but made a few adjustments. The issue is that the notebook container doesn't respond.

I tried these notebook images and called make nobteook_image:
jupyter/minimal-notebook:e1677043235c and jupyter/tensorflow-notebook:2c80cf3537ca (which is currently latest)

Maybe its due to some of my modifications:

• removed https stuff
• set port to 8080 (port 8000 is already in use by my gitlab server which is on the same host)
• set hub_port to 8081
• oauth via custom gitlab (works)
• assigned a subnet to the docker network docker network create --subnet=10.180.112.1/24 $(DOCKER_NETWORK_NAME) (otherwise it causes a conflict within my university's network)

I'm wondering if the issue is caused by the network setup.
jupyterhub-deploy-docker.zip
