The Complete Guide to Mastering Nextcloud AIO with Docker Compose 🚀☁️

🌟 What is Nextcloud AIO?

Nextcloud All-In-One (AIO) is the official solution to deploy all Nextcloud services with a single command!

• It is an integrated package: Automatic configuration of all components, including database (MySQL), reverse proxy (Traefik), backup system, etc.
• Automatic updates: support for one-click updates from the web UI 🔄.
• Security enhancements: integrated Let’s Encrypt TLS certificate, security enhancement settings by default

—.

⚙️ Prerequisites

1. install Docker & Docker Compose

   
   # Ubuntu example
   sudo apt update && sudo apt install docker.io docker-compose
   ```bash # Ubuntu example

2. Prepare a domain
   • Public domain required (for Let’s Encrypt certificate issuance)
   • Edit the hosts file for local testing (192.168.0.10 cloud.yourdomain.com)

🐳 Create a Docker Compose file

Example docker-compose.yml (based on the official template):

version: '3.8'

services:
  nextcloud-aio:
    container_name: nextcloud-aio
    image: nextcloud/all-in-one:latest
    restart: always
    ports:
      - 80:80
      - 8080:8080
      - 443:443
    volumes:
      - nextcloud_aio:/var/lib/docker
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      - APACHE_PORT=11000 # Internal Apache port.
      - apache_ip_binding=0.0.0.0.0
      - NEXTCLOUD_DATADIR=/nc_data # Data storage path
      - NEXTCLOUD_MOUNT=/mnt/nas # external storage mount (optional)
      - TRUSTED_PROXIES=192.168.0.0/24

volumes:
  nextcloud_aio:

🔍 Setup key points

1. **Port mappings

   • 80`: HTTP redirects
   • 443`: HTTPS traffic
   • 8080`: AIO management interface (for initial setup)

2. volume settings

   • nextcloud_aio: Store AIO metadata
   • Example of adding a host directory mount:

     volumes:
     - /mnt/ssd/nextcloud:/var/www/html

3. environment variables

   • trusted_proxies: IP banding when using load balancer/reverse proxy.
   • SKIP_DOMAIN_VALIDATION=true`: Skip domain validation when testing locally

—.

🚀 Running and Initialization

1. Start the service.

   docker-compose up -d

2. complete configuration (Web UI)

   • Access https://yourdomain.com:8080 → Follow the wizard to set up: (1) Create an administrator account → (2) Specify the data directory → (3) Confirm the domain

3. Automate deployment

   • After 5-10 minutes, you can log in to Nextcloud at https://yourdomain.com!

🛠️ Admin Tips & Troubleshooting

🔧 Useful commands

# Check AIO container logs
docker logs nextcloud-aio --tail 100

# Create a backup (AIO interface or CLI)
docker exec nextcloud-aio backup

# Update manually
docker-compose pull && docker-compose up -d

⚠️ Notes

• Mount /var/run/docker.sock required: required for AIO to create subcontainers
• Data backup: Regular backup of host volume path (/var/lib/docker/volumes/...)
• Port Conflict: Stop ports 80, 443 when using existing Nginx/Apache

🚨 Troubleshooting common errors

[ERROR] Can't connect to the Docker daemon

→ Check docker.sock permissions:

sudo chmod 666 /var/run/docker.sock # Temporary use in test environment only

—]

💡 Advanced Utilization

1. **Interfacing with external storage Add to docker-compose.yml after mounting NAS:

   volumes:
    - /nfs/nextcloud:/mnt/nas

   Select /mnt/nas path in Nextcloud settings → External Storage app

2. optimize performance

   environment:
    - PHP_MEMORY_LIMIT=4G
    - OPCACHE_ENABLE=1

3. Integrate Traefik (replace AIO built-in proxy) Refer to Official Guide

🎯 Why deploy with Docker Compose?

• Reproducibility: Ensure consistency across dev/test/production environments
• Extensibility: Easy to integrate additional services such as Redis, OnlyOffice, etc.
• Manageability: Version control your entire infrastructure with a single file
