• Download the `.deb` package:

wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64.deb

• Install the package using `dpkg`:

sudo dpkg -i cloudflared-linux-amd64.deb

• Verify the installation:

cloudflared --version

• Run the following command to log in and create a tunnel:

cloudflared tunnel login

• The authentication process will prompt you to open a URL in your browser to log in with your Cloudflare account.

• Create the tunnel and give it a name:

cloudflared tunnel create my-tunnel

• Note the tunnel ID and the location of the `cert.pem` file, which will be used for routing traffic.

• Create a configuration file:

sudo nano /etc/cloudflared/config.yml

• Example configuration:

tunnel: 72a29ddd==== TUNNEL ====cc4d8e3fc2ba
credentials-file: /home/facundo/.cloudflared/72a29ddd-7ef4-46e3-97ef-cc4d8e3fc2ba.json

ingress:
    - hostname: *.facundoitest.space
      service: http://192.168.88.250:443
    - service: http_status:404

• Start the tunnel:

sudo cloudflared tunnel run my-tunnel

• Ensure the tunnel is active and routing traffic correctly.

• Update the NGINX configuration on your Raspberry Pi to handle requests coming from the tunnel.

• Create a systemd service file:

sudo nano /etc/systemd/system/cloudflared.service

• Add the following configuration:

[Unit]
Description=Cloudflare Tunnel
After=network.target

[Service]
Type=simple
User=facundo
ExecStart=/usr/local/bin/cloudflared tunnel run my-tunnel
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

• Enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable cloudflared
sudo systemctl start cloudflared

• Check the status of the service:

sudo systemctl status cloudflared

• Ensure that the tunnel is running and NGINX is properly handling requests by checking the logs and testing the subdomains.

Following these steps will ensure that your `cloudflared` tunnel is correctly set up on your LXC and that it integrates smoothly with your existing reverse proxy setup on your Raspberry Pi.
