Jupyterhub in docker container not working with nginx reverse proxy #390

Open abashkinas opened 4 years ago

abashkinas commented 4 years ago

Bug description

Hello, I have started jupyterhub as a service in dockerswarm. Without nginx reverse proxy it works without problems. When I configure nginx reverse proxy with the following configuration:

server {

    listen 80;

    server_name jupyter.ifora.hse.ru;

    index index.html index.htm;

    access_log /var/log/nginx/jupyter.ifora.hse.ru-access.log ;
    error_log /var/log/nginx/jupyter.ifora.hse.ru-error.log error;

    location / {
      proxy_pass http://172.18.207.29:8000;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      # websocket headers
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
    }
}

The following messages begin to appear in the jupyterhub logs:

Please encapsulate your code into backticks (`) so that they are formatted appropriately. You can just edit your old entry.

As we can see in the logs, the error message stems from Jinja and it seems pretty awkward to me. I am not deeply rooted in the projects though. Have you tried running a debugger as described in https://code.visualstudio.com/docs/python/debugging to see what the template engine tries to do before it dies and creates problems for you?

This doesn't so much seem to be a problem with JupyterHub or the dockerspawner, but more with your nginx configuration. I would suggest that you direct these questions to https://discourse.jupyter.org which is a most welcoming forum.

As for your issue: JupyterHub will do a redirect to /hub if you hit it at the base path /, as indicated by the logs:

jupyter_hub.1.vkcroo6bu1zt@swarm_manager    | [I 2020-08-18 12:25:55.101 JupyterHub log:181] 302 GET / -> /hub/ (@172.18.207.29) 0.97ms
jupyter_hub.1.vkcroo6bu1zt@swarm_manager    | [I 2020-08-18 12:25:55.106 JupyterHub log:181] 302 GET /hub/ -> /hub/login (@172.18.207.29) 0.66ms

And the recursion limit being reached:

jupyter_hub.1.ry6cazaavyrc@swarm_manager    |     RecursionError: maximum recursion depth exceeded

Maybe try to stop nginx from also trying to do the redirection by adding to your location configuration:

    location / {
      [... the other configuration ...]
      proxy_redirect  off;
      [... the other configuration ...]
    }

I've managed to run several JupyterHubs inside Docker container. I've set my nginx as followed:

    location / {
            proxy_pass https://127.0.0.1:8000;

            proxy_set_header X-Real-IP $remote_addr;

            proxy_set_header X-Scheme $scheme;

            proxy_buffering off;
        }
        location ~* /(user/[^/]*)/(api/kernels/[^/]+/channels|terminals/websocket)/? {

            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            #proxy_set_header X-NginX-Proxy true;
