instant-subdomain-proxy

Automatic creation of HTTPS subdomain reverse proxy using nginx and certbot.

Prerequisites

1. A Debian-based system as the script uses apt.
2. The subdomain's A/AAAA DNS record must be configured to be pointing to this machine.
3. The machine must be able to receive the HTTP inbound message for certbot verification.

Usage

./create-proxy.sh {subdomain} {service-uri}

For example, let say you want to create a reverse proxy of a local service localhost:8080 to app1.example.com:

./create-proxy.sh app1.example.com localhost:8080
