docker compose file for setting up a nextcloud instance with postgres on arm32v7 qnap.

  • uses postgres as it is available for the arm32v7 architecture
  • creates a self signed certificate


  1. login to the webinterface of your NAS and open the container station application to create a new application:


  1. copy and past the content of the docker-compose.yml.

  2. make sure to set the postgres password in the docker-compose.yml: POSTGRES_PASSWORD=SUPERSECRETPASSWORD. if necessary change the port to which the nextcloud container gets exposed to. in this example it is 445 as the default port 443 it occupied by the NAS webinterface.

  3. create the application.

  4. to access the nextcloud instance via SSL we need to create a self signed certificate. access the shell of the nextcloud container.


activate ssl in apache

a2enmod ssl
a2ensite default-ssl

create a directory for the certificates and the certificates itself. openssl will ask for some information - make them up or leave them empty.

mkdir /etc/apache2/ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/nextcloud.key -out /etc/apache2/ssl/nextcloud.crt
cd ..

create the apache config file

echo "<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/nextcloud
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/apache2/ssl/nextcloud.crt
        SSLCertificateKeyFile /etc/apache2/ssl/nextcloud.key
</VirtualHost>" > nextcloud-ssl.conf

enable the config and restart apache

a2ensite nextcloud-ssl.conf
systemctl restart apache2.service
  1. now you can access your nextcloud instance via https://NAS-IP:445
  2. configure your nextcloud instance. when configuring the database use the settings from the docker-compose.yml and as hostname db.

if you want to use your nextcloud instance from outside your local network i would suggest following this guide: Docker-Compose with Let's Encrypt and NGINX
