How to setup Nextcloud AIO (with Docker & Caddy)

Untested

Description

Nextcloud is an open-source cloud storage platform.
It's a FOSS alternative to Google Drive, Microsoft OneDrive, Dropbox (and others).

Create a DNS record

Go to cPanel and add a new record (e.g. nextcloud.akdscloud.eu).

Caddy

nextcloud.akdscloud.eu:443 {
    # TLS and security headers
    header {
        Strict-Transport-Security "max-age=31536000;"
        X-XSS-Protection "1; mode=block"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "SAMEORIGIN"
        Referrer-Policy "no-referrer-when-downgrade"
    }

    request_body {
        max_size 34359738368 # 32GB in bytes
    }

    # Enhanced reverse proxy configuration
    reverse_proxy localhost:11000 {
        header_up X-Real-IP {remote_host}
        header_up Host {host}
    }
}

Folders

Create the folder structure

# Create Nextcloud data mount point
sudo mkdir -p /media/ncdrive
sudo chown dan:dan /media/ncdrive
sudo chmod 750 /media/ncdrive

Mount Storage for Nextcloud

# Get drive UUID
sudo blkid

# Add to /etc/fstab (replace UUID with your actual drive UUID)
sudo nano /etc/fstab
# Add line:
UUID=your-drive-uuid /media/ncdrive btrfs defaults 0 0

# Mount the drive
sudo mount -a

# Create and set permissions for Nextcloud data directory
sudo mkdir -p /media/ncdrive/ncdata
sudo chown -R 33:33 /media/ncdrive/ncdata
sudo chmod -R 750 /media/ncdrive/ncdata

# Verify permissions
ls -la /media/ncdrive
ls -la /media/ncdrive/ncdata

Docker

Add the nextcloud section to your docker-compose.yml file:

services:
  nextcloud-aio-mastercontainer:
    image: nextcloud/all-in-one:latest
    container_name: nextcloud-aio-mastercontainer
    restart: unless-stopped
    ports:
      - "8080:8080"
      - "8443:8443"
    environment:

      - MYSQL_TRANSACTION_ISOLATION=READ-COMMITTED
      - NC_DEFAULT_PHONE_REGION=RO
    volumes:
      - nextcloud_aio_mastercontainer:/mnt/docker-aio-config
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /media/ncdrive:/media/ncdrive
    depends_on:
      - caddy

volumes:
  nextcloud_aio_mastercontainer:
    name: nextcloud_aio_mastercontainer # This line is not allowed to be changed

Download and start nextcloud:
```
docker compose up -d nextcloud
```
Restart Caddy to get an SSL certificate (details here)

Try it out

See if you can access the nextcloud web interface.

Troubleshooting

If it doesn't work, see the troubleshooting guide.

Configuration

Initial Setup

Access the Nextcloud AIO interface at http://your_server_ip:8080
Complete the initial setup process
When prompted, configure:
- Domain: nextcloud.akdscloud.eu
- Data directory: /media/ncdrive/ncdata

How to change Nextcloud environment variables

docker stop nextcloud-aio-mastercontainer
docker rm nextcloud-aio-mastercontainer

Add/modify the (new) variable to your docker-compose file (in nextcloud --> environment).

Then simply restart the services:

docker compose up -d nextcloud-aio-mastercontainer

Also, you will need to stop the NC containers (from the web interface) and then restart them.

Afterwards, check if your changes we made.

No data is lost during this process. And you don't need to redo the whole setup again.
