Allow running TLJH under a URL prefix

[yuvipanda]

Currently TLJH runs in the root of the domain (example.com), and can not easily work under a URL prefix (example.com/hub). Would be nice to support this.

Setting c.JupyterHub.base_url = '/jupyterhub/' should be everything that's needed for this, so I think this should just be a docs update.

Hello,

Thanks. It worked correctly by setting c.JupyterHub.base_url.

How about traefik.toml for sharing with other services, such as nbviewer.

I tried as below and it worked.
pip install nbviewer at TLJH user(conda) env.
python3 -m nbviewer --localfiles=/public --port=5000

For setting based on traefik service.
It looks like possible by updating traefik.toml.tpl at soruce.

Do you have any guide for sharing traefik service ?

Thanks in advance.

Hi,

Below is my updating traefik.toml to share treafik service between jupyterhub and nbviewer.
nbviewer is an public web service based on docker container, just sharing public folders with jupyterhub by mounting the folders at the container.

[frontends.default]
backend = "jupyterhub"
passHostHeader = true
priority = 100
[frontends.default.routes.rule1]
rule = "Path:/;AddPrefix:/jupyterhub"

[frontends.jupyterhub]
backend = "jupyterhub"
passHostHeader = true
priority = 90
[frontends.jupyterhub.routes.rule1]
rule = "PathPrefix:/jupyterhub"

[frontends.nbviewer]
backend = "nbviewer"
passHostHeader = true
priority = 80
[frontends.nbviewer.routes.rule1]
rule = "PathPrefix:/nbviewer"

[backends]
[backends.jupyterhub]
[backends.jupyterhub.servers.chp]
url = "http://127.0.0.1:15003"

[backends.nbviewer]
[backends.nbviewer.servers.nbv]
url = "http://127.0.0.1:25000"

Welcome any better approaches.

Hello,

I added an extra_config.py file under /opt/tljh/config/jupyterhub_config.d/ with c.JupyterHub.base_url = '/jupyter/'. However, when I run tljh-config reload hub it does not exit and remains stuck in a loop with the following continuous output:

/opt/tljh/hub/lib/python3.6/site-packages/urllib3/connectionpool.py:988: InsecureRequestWarning: Unverified HTTPS request is being made to host '127.0.0.1' etc...
