Nextcloud

In this guide, we will deploy Nextcloud using Docker Compose with MariaDB as the database. This setup is simple, stable, and works well for home labs and self-hosted environments.

Requirements

• Docker installed
• Docker Compose installed
• Server running Linux (Ubuntu recommended)

---

Docker Compose File

Create a new directory

mkdir nextcloud
cd nextcloud

Create the docker-compose.yml file

services:
  db:
    image: mariadb:10.6
    restart: unless-stopped
    command: --transaction-isolation=READ-COMMITTED --log-bin=binlog --binlog-format=ROW
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=nextcloud
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  app:
    image: nextcloud
    restart: unless-stopped
    links:
      - db
    volumes:
      - nextcloud:/var/www/html
    environment:
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db
    ports:
      - 8080:80

volumes:
  nextcloud:
  db:

Start the Containers

docker-compose up -d

Once started, open Nextcloud in your browser http://YOUR-SERVER-IP:8080

Complete the web installation interface.

Using occ Command (Optional)

docker exec -u www-data nextcloud-app-1 ./occ

Conclusion

You now have a fully functional Nextcloud instance running with Docker Compose. You can optionally place it behind a reverse proxy like Nginx Proxy Manager or Traefik to enable HTTPS and domain access.
