I’m trying to set up jupyter lab behind an nginx reverse proxy on the subpath /jlab
Here’s my minimal example:
docker-compose.yml
version: "3.7"
services:
nginx:
image: nginx:alpine
volumes:
- "./default.conf:/etc/nginx/conf.d/default.conf:ro"
ports:
- 8080:80
links:
- "jupyterlab"
jupyterlab:
image: jupyter/scipy-notebook
container_name: jupyterlab
volumes:
- "./jupyter_server_config.py:/home/jovyan/.jupyter/jupyter_server_config.py:ro"
default.conf
server {
listen 80;
listen [::]:80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location /jlab {
proxy_pass http://jupyterlab:8888;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_redirect off;
proxy_buffering off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
}
}
jupyter_server_config.py
c.ServerApp.allow_remote_access = True
c.ServerApp.allow_root = True
c.ServerApp.base_url = '/jlab'
c.ServerApp.ip = '*'
c.ServerApp.token = u''
This can be run with docker compose up --build -d
jupyterlab can now be reached at localhost:8080/jlab
Everything appears to be working. But if you look at the logs you get this repeated message:
jupyterlab | [W 2022-08-06 00:18:27.783 ServerApp] 404 GET /api (127.0.0.1) 1.04ms referer=None
The status of the container turns to Up About a minute (unhealthy), so I’m guessing this will be a problem, but I’m not sure what the problem is or how to fix it.
