Exemple de génération de certificats. Notez que Traefik est capable d'utiliser **Let's Encrypt**
<code bash>
mkdir certs
openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/wildcard.docker.local.key -x509 -days 365 -out certs/wildcard.docker.local.crt
</code>

<code bash>
docker-compose up -d
