DigitalOcean
Quick Install
You can use our droplet which is registered in the DigitalOcean Marketplace under the name Supabase Realtime.
Before we start, this droplet enables UFW that allows port 22 for SSH, port 5432 for PostgreSQL, and port 4000 for serving Supabase Realtime subscriptions. If you want to use different ports for your PostgreSQL database or Realtime, you have to configure UFW to allow those ports. Otherwise, read on!
Once the droplet is up and running, you first need to point Realtime to listen to your PostgreSQL database. First, SSH to the droplet instance, and edit /etc/realtime/realtime.env:
You'll see some environment variables you will need to set. If you are using our Supabase Postgres droplet, you simply need to set DB_HOST to the Postgres droplet's public IP, DB_PASSWORD to the password you set with \password postgres, and SECRET_KEY_BASE to a randomly generated secret which you can get by running the command below:
Now you need the Realtime service to use the newly set environment variables:
You can now disconnect from SSH. Now you should be able to visit your Realtime endpoint at http://your_realtime_droplet_ip:4000 and receive the greeting page, which means you're ready to subscribe to changes to your database with Realtime!
