• Nextcloud benötigt zur Funktion eine Datenbank und einen Webserver
• Let's encrypt benötigt zur Funktion einen Webserver

Daher benötigen wir die Dienste in dieser Reihenfolge:

• Webserver - nginx-Reverse Proxy
• SSL - Let's encrypt
• Datenbank - MariaDB
• App - Nextcloud

su - docker

mkdir -p ~/projects/nextcloud/
cd ~/projects/nextcloud/

nano .env

LETSENCRYPT_HOST=<your.domain></your.domain>
