The official Certbot documentation (https://certbot.eff.org/instructions) does not provide configuration examples for Docker and Docker Compose. This guide fills that gap.

1. Copy the certbot service from docker-compose.yml file

2. Add volumes to your nginx service using docker-compose.yml example

3. Change nginx conf, add location into your server section for port 80 and 443, which shares the location for ACME challenges location /.well-known/acme-challenge/ { root /var/www/certbot; } into 80 and 403 ports

4. run certbot container and inside this conainer run command: certbot certonly -d yourdomain.com --webroot -w /var/www/certbot

5. Add in 443 port server section

ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;

into nginx.conf

docker-compose
