Hi ,
I am new to JH and wanted to run dockerised JH with DockerSpawner spawning docker containers for each user.
Based on GitHub - jupyterhub/jupyterhub-deploy-docker: Reference deployment of JupyterHub with docker I want to use sapwner with native authentication (GitHub - jupyterhub/nativeauthenticator: JupyterHub-native User Authenticator https://native-authenticator.readthedocs.io/en/latest/).
My main problem is with connections /networs - i think 
My configs are as follows:
.env file for docker compose:
#------------------------------------------------------------------
#JupyterHub
#------------------------------------------------------------------
# To override these values, set the shell environment variables.
JUPYTERHUB_VERSION=2.3.1
# Name of Docker machine
DOCKER_MACHINE_NAME=jupyterhub
# Name of JupyterHub container data volume
DATA_VOLUME_HOST=jupyterhub-data
# Name of Docker network
DOCKER_NETWORK_NAME=jupyterhub-network
DATA_VOLUME_HOST=jupyterhub-data
docker-compose.yml:
version: "3.9"
services:
jupyterhub: # Configuration for Hub
build:
context: ./jupyterhub/ # path to the Dockerfile
args:
JUPYTERHUB_VERSION: 2.3.1
image: mc_jupyterhub_img:v1 # image name
container_name: jh_container # container name

tty: true
stdin_open: true
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:rw"

environment:

DOCKER_NETWORK_NAME: ${DOCKER_NETWORK_NAME}
env_file:
- .env
command: >
jupyterhub --debug -f /etc/jupyterhub/jupyterhub_config.py
networks:
jupyterhub-network:
name: ${DOCKER_NETWORK_NAME}
jupyter_config.py:
import os
c = get_config()
import nativeauthenticator

c.JupyterHub.template_paths = [f"{os.path.dirname(nativeauthenticator.__file__)}/templates/"]
c.Authenticator.admin_users = {"myadmin"}

c.DockerSpawner.use_internal_ip = True
c.DockerSpawner.network_name = network_name
c.DockerSpawner.extra_host_config = { 'network_mode': network_name }
c.DockerSpawner.remove = True
JupyterHub ‘Dockerfile’
ARG JUPYTERHUB_VERSION
FROM jupyterhub/jupyterhub:$JUPYTERHUB_VERSION
# Copy the JupyterHub configuration in the container
COPY jupyterhub_config.py /etc/jupyterhub/jupyterhub_config.py
RUN apt-get update &&\
apt-get install python3-netifaces
# Install dependencies (for advanced authentication and spawning)
RUN pip install \
dockerspawner\
jupyterhub-nativeauthenticator
However, I can’t spawn my jupyterlab notebook due to 500 redirects:
I can create some myadmin user and sign in but when I click `Start server i get teh above error with following log:
sudo docker-compose up
