How to Set Up Nextcloud on Docker for Private Storage

Self-Hosted Cloud Storage: Deploying Nextcloud via Docker

Taking complete ownership of your personal files, photo libraries, contacts, and calendar events is simple with Nextcloud. By deploying Nextcloud inside a Docker Compose environment paired with a MariaDB database and Redis cache, you eliminate monthly cloud subscription fees while maintaining total data privacy. At Android People (androidpeople.in), we share a complete step-by-step deployment guide.

Step 1: Preparing Project Directories

Connect to your Linux server via SSH, create a dedicated directory named nextcloud, and navigate into it:

mkdir -p ~/nextcloud && cd ~/nextcloud

Step 2: Writing Docker Compose Configuration File

Create a file named docker-compose.yml and add the following configuration stack:

version: '3.8'
services:
  db:
    image: mariadb:10.11
    restart: always
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    volumes:
      - db_data:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=YourSecureRootPassword
      - MYSQL_PASSWORD=YourDatabasePassword
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  redis:
    image: redis:alpine
    restart: always

  app:
    image: nextcloud:latest
    restart: always
    ports:
      - 8080:80
    volumes:
      - nextcloud_data:/var/www/html
    environment:
      - MYSQL_PASSWORD=YourDatabasePassword
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db
      - REDIS_HOST=redis
    depends_on:
      - db
      - redis

volumes:
  db_data:
  nextcloud_data:

Step 3: Launching Containers and Initial Web Setup

Launch the container stack in detached mode by running:

docker compose up -d

Once the containers are running, open a web browser and navigate to http://<YOUR_SERVER_IP>:8080. Create your administrator account and follow the wizard to complete initial setup.

Frequently Asked Questions

Should I use Nextcloud All-in-One (AIO) or custom Docker Compose?
Nextcloud AIO is recommended for users wanting automated backups and built-in SSL, while custom Docker Compose offers full flexibility for existing reverse proxy environments.
