Jupyter notebook on AWS with NGINX

We managed to get Jupyter notebook up in the cloud on AWS in this previous post.

However, it’s not really sustainable to have to keep adding the port 8888 at the end of the URL.

We shall add Nginx to the mix. Nginx is a HTTP server, which will allow us to redirect HTTP and HTTPS requests alike to the local server on port 8888.

Nginx

First, we install Nginx. SSH in as per the previous post.

sudo apt-get update
sudo apt-get install nginx

Once Nginx is installed, add the configuration file at /etc/nginx/conf.d/

nano sudo /etc/nginx/conf.d/configuration.conf

Copy and paste the lines below.

upstream notebook {
	server localhost:8888;
}

server {
	listen                    80;
	listen                    443;
	ssl                       on;
	server_name               54.213.41.70;
	ssl_certificate           /home/ubuntu/certs/mycert.pem;
	ssl_certificate_key       /home/ubuntu/certs/mycert.pem;
	ssl_protocols             TLSv1 TLSv1.1 TLSv1.2;
	access_log                /home/ubuntu/logs/nginx.access.log;
	error_log                 /home/ubuntu/logs/nginx.error.log;

	location / {
		proxy_pass            https://notebook;
		proxy_set_header      Host $host;
	}

	location ~ /api/kernels/ {
		proxy_pass            https://notebook;
		proxy_set_header      Host $host;
		# websocket support
		proxy_http_version    1.1;
		proxy_set_header      Upgrade "websocket";
		proxy_set_header      Connection "Upgrade";
		proxy_read_timeout    86400;
	}
}

This will neatly bring us via HTTPS from /notebook to the localhost:8888.

We need to first restart Nginx though.

sudo service nginx restart

And that’s it.
