Setting up Nextcloud

The official image plus a database container, then the setup wizard does the rest in the browser.

  1. 1

    Run the containers

    Nextcloud needs a real database for anything beyond casual use; MariaDB is the most common pairing.

    services:
  nextcloud:
    image: nextcloud:latest
    container_name: nextcloud
    restart: unless-stopped
    ports:
      - "8081:80"
    volumes:
      - ./data:/var/www/html
    depends_on:
      - db

  db:
    image: mariadb:11
    container_name: nextcloud-db
    restart: unless-stopped
    environment:
      - MYSQL_ROOT_PASSWORD=change-this
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_PASSWORD=change-this-too
    volumes:
      - ./db:/var/lib/mysql
  2. 2

    Run the setup wizard

    The first visit to port 8081 asks for an admin account and the database connection details, matching the environment variables set above.

  3. 3

    Install the sync clients

    Desktop apps for Windows, macOS, and Linux, plus mobile apps for iOS and Android, all point at this server's address and sync a chosen folder automatically, the same experience as Dropbox.

  4. 4

    Add more apps as needed

    The built-in App Store (gear icon → Apps) has official add-ons for Calendar, Contacts, and browser-based document editing (Nextcloud Office), each one turning this from file sync into a fuller productivity suite.
