Certbot and letsencrypt require a first validation over http (port 80). If you run an nginx configured with https and http auto-redirect to 443 letsencrypt can't validate your environment.
For this reason I created this simple docker-compose and script that deploy a docker compose with a step procedure to start, validate and deploy full TLS website.
By the way, the nginx.conf has a lot configuration to use nginx (and your web server) with some best practices.
Feel free to configure as you need ...and, obviously, send me a PR ;)
- a server with public ip
- a dns associated to that IP address
