Host NextCloud

NextCloud is a free and open-source file hosting service that allows you to store your files in a centralized location and sync them across devices. NextCloud is an alternative to proprietary services like Dropbox, Google Drive, and Microsoft OneDrive. NextCloud is self-hosted, which means you can host it on your own server and have full control over your data.

To host NextCloud on AnduinOS, run the following commands.

First, make sure Docker is installed on your machine. If not, you can install Docker by running the following commands:

Install Docker

curl -fsSL get.docker.com -o get-docker.sh
CHANNEL=stable sh get-docker.sh
rm get-docker.sh

Create a new folder to save the service configuration files:

Prepare a clean directory

# Please install Docker first
mkdir -p ~/Source/ServiceConfigs/nextcloud
cd ~/Source/ServiceConfigs/nextcloud

Make sure no other process is taking 80 port on your machine.

Check if the port is occupied

function port_exist_check() {
  if [[ 0 -eq $(sudo lsof -i:"$1" | grep -i -c "listen") ]]; then
    echo "$1 is not in use"
    sleep 1
  else
    echo "Warning: $1 is occupied"
    sudo lsof -i:"$1"
    echo "Will kill the occupied process in 5s"
    sleep 5
    sudo lsof -i:"$1" | awk '{print $2}' | grep -v "PID" | sudo xargs kill -9
    echo "Killed the occupied process"
    sleep 1
  fi
}

port_exist_check 80

Then, create a docker-compose.yml file with the following content:

Create a docker-compose.yml file

cat << EOF > ./docker-compose.yml

Then, deploy the service:

Deploy the service

sudo docker swarm init  --advertise-addr $(hostname -I | awk '{print $1}')
sudo docker stack deploy -c docker-compose.yml nextcloud --detach

You need to update the permission for /mnt/data inside the container. You can do this by running the following command:

Update the permission for /mnt/data

sudo docker exec -it $(sudo docker ps -qf "name=nextcloud_web") chown -R www-data:www-data /mnt/data
sudo docker exec -it $(sudo docker ps -qf "name=nextcloud_web") chmod -R 0770 /mnt/data

You can access NextCloud by visiting http://localhost in your browser.

The default user is set during the first login.

During initial setup, it may ask you the password for the database. You can use the following credentials:

Database: nextcloud
User: nextcloud
Password: dbpassword

That's it! You have successfully hosted NextCloud on AnduinOS.

Uninstall

To uninstall NextCloud, run the following commands:

Uninstall NextCloud

sudo docker stack rm nextcloud
sleep 20 # Wait for the stack to be removed
sudo docker system prune -a --volumes -f # Clean up used volumes and images

To also remove the data, log, and config files, run the following commands:

Remove the data, log, and config files

sudo rm /swarm-vol/nextcloud -rf

That's it! You have successfully uninstalled NextCloud from AnduinOS.
