Setup

Create your .env (see example.env)

DB_NAME=mydb
DB_USER=myuser

HOSTNAME=example.com

Setting up certificates

To initialize your ssl certificate run the following

export NGINX_CONFIG_FILE=nginx.challenge.conf && \
docker compose up -d webserver
docker compose run --rm certbot certonly --webroot --webroot-path /var/www/certbot/ --dry-run

Note: --dry-run is included for testing purposes, remove it once you have tested your setup

Once you have the certificate, reset your NGINX_CONFIG_FILE to the default

export NGINX_CONFIG_FILE=nginx.conf && \
docker compose up -d webserver

Certificate renewal

Renew the certificate

docker compose run --rm certbot renew

Test and reload nginx

docker compose exec webserver nginx -t && \
docker compose exec webserver nginx -s reload

You can use the included renew-ssl.sh in crontab, make sure to change the paths as needed
