Nginx + LetsEncrypt configuration for docker-compose usage

assume you have already created a certificate

1. sudo ufw allow 80 && sudo ufw allow 443
2. sudo apt install letsencrypt
3. sudo certbot certonly --standalone --agree-tos --preferred-challenges http -d [example.org]

The certonly option means that the certificate will only be obtained without installation on any web server, standalone allows you to start your own web server for authentication, agree-tos means acceptance of the ACME server subscription agreement, which is a prerequisite, and preferred-challenges http means performing authorization using HTTP
