Cloudflared Setup Guide

This guide will walk you through setting up Cloudflared on your system.

Pre-Requisites

You need to have administrative (doas) access to your system.

Add nano editor using: doas apk update && doas apk add nano

Here are the steps to install Cloudflared.

# Download the latest version of cloudflared, change `arm64` to `arm` at the end of the URL for 32-bit version.
doas wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64 -O /usr/bin/cloudflared

# Give executable permissions to the downloaded file
doas chmod +x /usr/bin/cloudflared

# Check the version of cloudflared to confirm the installation
cloudflared -v

Creating a Cloudflare Tunnel

After installing Cloudflared, you need to create a Cloudflare tunnel.

1. Visit https://one.dash.cloudflare.com.
2. Navigate to Networks -> Tunnels -> Create a tunnel.
3. Fill in a name you like and save the tunnel.
4. Find the code block below After you have installed cloudflared on your machine, you can install a service to automatically run your tunnel whenever your machine starts:.
5. Replace sudo with doas before executing. Make note of the your <TOKEN> which comes after sudo cloudflared service install

Starting the Cloudflared Service, while sustaining reboots

To automatically start the Cloudflared service on your machine, follow the steps below:

# Backup the original SysVinit file created by Cloudflared
doas mv /etc/init.d/cloudflared /etc/init.d/cloudflared.bak

# Create a new service file using:
doas nano /etc/init.d/cloudflared

With the following contents, replace <TOKEN> with the one noted above:

#!/sbin/openrc-run

name=$(basename $(readlink -f $0))

pidfile="/var/run/$name.pid"

command="/usr/bin/cloudflared"

command_args=" --pidfile /var/run/$name.pid  --autoupdate-freq 24h0m0s tunnel run --token <TOKEN>"

command_background=yes

stdout_log="/var/log/$name.log"

stderr_log="/var/log/$name.err"

depend() {
	need net
	after firewall
	use logger dns
}

Make the service file executable:

doas chmod +x /etc/init.d/cloudflared

Now, add the service file to OpenRC:

# Remove the service from the default runlevel (just in case it was added earlier)
doas rc-update del cloudflared

# Add the service to the default runlevel
doas rc-update add cloudflared default

# Start the service immediately
doas rc-service cloudflared start

That's it! You have successfully installed and set up Cloudflared on your system.
