## What it is
A Docker image wrapping the official Nginx images with automatic Let's Encrypt certificate creation and renewal via certbot. It supports RSA and ECDSA certs, wildcard domains through DNS-01 challenges, Diffie-Hellman parameter generation, and offline use with a local CA.

## Use cases
- automatically create and renew free SSL certificates for my website
- run nginx with https in docker without manual certbot setup
- get wildcard certificates using DNS-01 challenge
- self-host services with automatic Let's Encrypt renewal
- generate dhparam and ecdsa certificates automatically
- use nginx with local CA certificates for offline development
- serve multiple domains and subdomains with one nginx container

## When to choose
- you want a nearly zero-maintenance nginx reverse proxy with automatic HTTPS
- you need wildcard certificates via DNS authentication plugins
- you deploy on Docker and want cert renewal handled inside the container
- you need multi-architecture images (including ARM) for self-hosting

## When to avoid
- you use a web server other than nginx such as Caddy or Traefik
- you need a non-Docker bare-metal certbot setup
- you require fine-grained custom ACME workflows better served by raw certbot or acme.sh
