'tljh-config set http.port' option does not work

[taeshahn]

Hi. I tried to set up The Littlest JupyterHub on a machine whose 80 port is already in use by apache2. I added the config to change the port of TLJH from 80 to 8080, and then reloaded/restarted the service. it seems that, however, the port change option does not work. How should I do in this case?

admin@server:~$ sudo tljh-config show

users:
  admin:
  - adminuser
http:
  port: 8080
user_environment:
  default_app: jupyterlab

admin@server:~$ sudo tljh-config reload

active
Hub reload with new configuration complete

admin@server:~$ sudo service jupyterhub restart

admin@server:~$ sudo netstat -tnlp (traefik still listen on 80 port)

Thank you in advance :)

Hi @ts-han! Thanks for reporting this.

http.port is part of the proxy's configuration, so in order for the change to take place, the proxy's configuration should be also reloaded with:

sudo tljh-config reload proxy

tljh-config reload can be used to either reload the hub or the proxy. If no arguments are provided, it defaults to hub.

Thank you, @GeorgianaElena!

sudo tljh-config reload proxy works well!

Happy it worked @ts-han! I'm going to close this issue now, but feel free to open a new one if you have any other question.
