Raspberry Pi as your Cloud Storage - with Nextcloud & Docker

To install nextcloud in RPi, we need to include a DB.

For example, lets use MariaDB in the installation (it supports ARM/x86 processors, not like mysql).

Installing Docker Stuff

First things first.

Get Docker and Docker-Compose ready in your Rpi.

Deploy Nextcloud with Docker

Let’s use Docker-Compose to have nextcloud server installed without any complications.

See the Nextcloud config file and more here

version: '2'

volumes:
  nextcloud:
  db:

services:
  db:
    image: linuxserver/mariadb
    restart: always
    container_name: nextclouddb
    volumes:
      - /home/Docker/nextcloud/db:/var/lib/mysql
    environment:
      - MYSQL_INITDB_SKIP_TZINFO=1
      - MYSQL_ROOT_PASSWORD=rootpass
      - MYSQL_PASSWORD=ncpass
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
#    networks: ["nginx_nginx_network"] #optional 

  app:
    image: nextcloud #latest #27.0.0
    container_name: nextcloud
    restart: always
    ports:

FAQ

Remember to update the list of trusted domains so that other devices can log, we can see the current list with:

sudo docker exec --user www-data nextcloud_container php occ config:system:get trusted_domains

To add a new domain/internal/local ip, simply pass it in the end of this CLI command:

sudo docker exec --user www-data nextcloud_container php occ config:system:set trusted_domains 7 --value 192.168.1.22:8080
#sudo docker exec --user www-data nextcloud_container php occ config:system:set trusted_domains 7 --value nextcloud.yourgreatname.duckdns.org

Remember that you can check your device (the RPi here) internal IP adress with:

hostname -I

To access nextcloud while being out of home, simply configure your VPN, for example with tailscale, and add the internal Ip address assign by tailscale as shown two commands before.

You can also see your files with the WebDav, just add in your file manager:

davs://example.com/nextcloud/remote.php/dav/files/USERNAME/
davs://nextcloud.yourgreatname.duckdns.org/nextcloud/remote.php/dav/files/USERNAME/

If your server connection is not HTTPS-secured, use dav:// instead of davs://.

Alternatively - you can try FileBrowser

How to use a External Drive with NextCloud

lsblk
lsblk -a
lsblk -f
sudo fdisk -l

Once you have identify the drive, format it (for example) with NTFS:

#sudo mkfs.ntfs /dev/sda1 #make sure it is /dev/sda1 as well for you
#sudo mkfs.ntfs -Q /dev/sda1 #quick version

sudo mkdir /usbdrive
sudo mount /dev/sda1 /usbdrive

If you df -h - you will see the drive mounted.

And you can always copy the data with:

#sudo cp -R ./files/* /mnt/mydrive/
sudo rsync -avh --progress ./files/* /mnt/mydrive/ #with progress

And you can check the full size of the copied folder

du -sh ./files
