Reverse Proxy Prometheus with Nginx
Video Lecture
Description
One option to help secure our Prometheus server is to put it behind a reverse proxy so that we can later add SSL and an Authentication layer over the default unrestricted Prometheus web interface.
We can use Nginx.
sudo apt install nginx
CD to the Nginx sites-enabled folder
cd /etc/nginx/sites-enabled
Create a new Nginx configuration for Prometheus
sudo nano prometheus
And copy/paste the example below
server {
listen 80;
listen [::]:80;
server_name YOUR-DOMAIN-NAME;
location / {
proxy_pass http://localhost:9090/;
}
}
Save and test the new configuration has no errors
nginx -t
Restart Nginx
sudo service nginx restart
sudo service nginx status
Test it by visiting again
http://YOUR-DOMAIN-NAME
Visiting your IP address directly will still show the default Nginx welcome page. If you don't want this to happen, then you can delete its configuration using the command below.
rm /etc/nginx/sites-enabled/default
