Nginx Let's Encrypt Proxy

This repository contains the necessary configuration files and instructions to set up an Nginx reverse proxy with Let's Encrypt SSL certificate.

Prerequisites

Before getting started, make sure you have the following:

  • A registered domain name

Installation

  1. Copy the nginx.conf and change the server_name to your domain and the proxy_pass to your application.

  2. Upload the nginx.conf to Gist or any other file hosting service. Make sure the file is publicly accessible.

  3. Go to console.akash.network and create a new deployment with the SDL in deploy.yml.

  4. Replace the NGINX_CONF_URL in the SDL with the URL of the nginx.conf file you uploaded in step 2.

  5. Replace the DOMAIN in the SDL with your domain name.

  6. Make sure FIRST_START is set to true in the SDL.

  7. Deploy the application and select a Provider.

  8. Once the deployment starts, you can see the leased IP address in the Leases tab of the Akash Console. Copy the IP address and create an A record in your domain's DNS settings pointing to this IP address.

  9. Wait for the DNS changes to propagate. You can check the status of the DNS propagation using online tools like DNS Checker.

  10. Update the FIRST_START to false in the SDL.

  11. You should now be able to access your application using your domain name over HTTPS.

A successful deployment should look similar to this:

FAQ

How do I renew the SSL certificate?

The SSL certificate is automatically renewed by Certbot. You don't need to do anything to renew the certificate.

How do I update the Nginx configuration?

To update the Nginx configuration, you need to update the nginx.conf file and upload it to a publicly accessible URL. Then update the NGINX_CONF_URL in the SDL with the new URL. Note that it will recreate the Certificate.

What do i do if i run in to the error too many registrations for this IP?

If you run into the error too many registrations for this IP, it means that you have reached the Let's Encrypt rate limit for the number of registrations from a single IP address. You can wait for the rate limit to reset or use a different Provider to register the certificate.
