Installation Instructions Using Docker Compose

Installing Nextcloud using Docker Compose allows you to set up your cloud server quickly and efficiently. Docker Compose manages the configuration and orchestration of the necessary containers, simplifying the deployment process.

Prerequisites
  • Ubuntu server (18.04 or later)
  • Docker and Docker Compose installed
Docker Compose Configuration for Nextcloud

  1. Create a Directory for Nextcloud:

    mkdir nextcloud
cd nextcloud

  2. Create a Docker Compose File:

    Create a file named docker-compose.yml in the Nextcloud directory with the following content:

    services:
  db:
    image: mariadb
    restart: unless-stopped
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW --innodb-file-per-table=1 --skip-innodb-read-only-compressed
    volumes:
      - ${DOCKER}/nextcloud/db:/var/lib/mysql
    env_file:
      - .env

  redis:
    image: redis
    restart: always
    command: redis-server --requirepass  ${REDIS_HOST_PASSWORD}

  app:
    image: icsy7867/nextcloud:latest
    restart: unless-stopped
    ports:
      - ${HTTP_PORT}:80
    links:
      - db
      - redis
    volumes:
      - ${DOCKER}/nextcloud/var:/var/www/html
    environment:
      - MYSQL_HOST=${MYSQL_HOST}
      - REDIS_HOST_PASSWORD=${REDIS_HOST_PASSWORD}
    env_file:
      - .env
    depends_on:
      - db
      - redis

    This configuration sets up Nextcloud and MySQL containers, maps port 8080 for web access, and manages data persistence with Docker volumes.

  3. Start the Nextcloud Containers:

    Run the following command to start Nextcloud using Docker Compose:

    sudo docker-compose up -d

    This command downloads the Nextcloud and MySQL Docker images (if not already available), creates and starts the containers in detached mode.

  4. Verify the Installation:

    Open your web browser and navigate to http://<your_server_ip>:8080 to access the Nextcloud web interface. You should see the Nextcloud setup page if the installation was successful.

Basic Setup Instructions

  1. Initial Configuration:

    After navigating to http://<your_server_ip>:8080, you will see the Nextcloud setup page. Create an admin account by providing a username and password. Configure the database connection using the details from the docker-compose.yml file (e.g., database user, password, and database name).

  2. Configure Email Settings:

    Set up email notifications by configuring the SMTP server settings in Nextcloud. Go to Settings > Basic settings > Email server and enter your SMTP server details.

  3. Connect External Storage:

    To integrate with external storage services, go to Settings > External storage and add the external storage providers (e.g., Dropbox, Google Drive, Amazon S3) you want to use.

  4. Install Apps:

    Enhance Nextcloud’s functionality by installing additional apps. Visit the Nextcloud App Store to browse available apps and install them directly from the Nextcloud interface.

  5. Set Up Nextcloud Talk:

    Install and configure Nextcloud Talk for secure video and audio calls. This app provides integrated communication features within your Nextcloud instance.

  6. Create and Manage Users:

    Create additional user accounts and manage permissions from the Users section in the Nextcloud admin settings. Set up groups and assign roles to control access to different parts of your Nextcloud instance.
