Add an SSL Certificate for HTTPS

This is the last step in this tutorial If you do not have a domain name yet, you can skip this part.
If you have a domain name assigned to the application, we can install a Free SSL certificate using Let’s Encrypt. It is always recommended to secure your website with an SSL certificate.

We need to install the Certbot client on our server.

sudo apt install certbot python3-certbot-nginx -y

Once Certbot is installed, you can now request an SSL certificate for your domain name

sudo certbot --nginx -d example.com

This will generate an SSL certificate for you and certbot will rewrite your Nginx configuration file to handle redirects from HTTP to HTTPS and also set the path to the SSL certificates.

By default Let’s Encrypt certificates expire after 90 days and we might want to renew them as soon as they expire.
