Add a volume to frontend if you want to keep let's encrypt configurations and certificates after update:

• ./letsencrypt:/etc/letsencrypt

./letsencrypt will contain the data, you won't need to setup SSL again after restarting/recreating the containers.

Deploy and Setup SSL

docker-compose up -d
docker exec -it <frontend_container> bash       # bash into the nginx container
certbot --nginx -d domain.com -d www.domain.com     # setup SSL certificate
