Reverse Proxy Prometheus with Nginx Reverse Proxy Prometheus with Nginx


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


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
