docker NGINX server sub location issue - docker

Question

I have the following NGINX that works without issue for root https / . However whenever I try to change location / { to a subdomain like location /example { it breaks everything. if you go to domain.com/exmaple it takes you to a 404 error no matter where you go.

You're missing the root parameter in your nginx configuration.
You should check in the guide how to use it http://nginx.org/en/docs/beginners_guide.html
It reports you should do something like
location / {
root /var/www/webapp/public; // something like that
// .. config
}
location ~* /(api/kernels/[^/]+/(channels|iopub|shell|stdin)|terminals/websocket)/? {
root /var/www/webapp/api; // something like that
// .. config
}
