Expose localhost to the internet
Cloudflare Tunnel provides you with a secure way to
connect your resources to Cloudflare without a publicly
routable IP address. With Tunnel, you do not send traffic to an external IP — instead,
a lightweight daemon in your infrastructure (cloudflared) creates
outbound-only connections to Cloudflare’s edge. Cloudflare Tunnel
can connect HTTP web servers, SSH servers, remote desktops, and other
protocols safely to Cloudflare. This way, your origins can serve
traffic through Cloudflare without being vulnerable to attacks that bypass
Cloudflare.

Source Cloudflared |
How it works
Cloudflared establishes outbound connections (tunnels) between your resources and the Cloudflare edge. Tunnels are persistent
objects that route traffic to DNS records. Within the same
tunnel, you can run as many cloudflared processes
(connectors) as needed. These processes will establish connections to
the Cloudflare edge and send traffic to the nearest
Cloudflare data center.
Here we can use cloud tunnel with 2 methods and the first one is installed the cloud tunnel in your system and other one is through binary method.
Cloud Tunnel
First of all let's see how we can install it and use it, first of all
we have copied its deb file. After this download in your terminal,
for this you will use this command.
sudo wget

Lets see how to install it after download deb file, you can use this command for installation -

for this you have to use this command

But before that you have to enable Apache webserver service on your
system.

Let's see the demo that we can open our webpage by sitting
anywhere from the internet on our local webserver.
Here I
have made a webpage on my system's localhost, so as you can see
Here you can type the URL of your localhost or you
can also write the IP address or if you web page is running on any
particular port then you can use this way.
- localhost
- 127.0.0.1

Here the tunnel of cloud flare will start and here you will get
the external link from where you can access the webpage through that
link.
https://justify-caribbean-surveillance-align.trycloudflare.com
So as you can you can use this URL to anywhere to open your webpage.
Binary Format
Now we will use cloud flare tunnel through binary format and lets see how to run localhost webpage in cloud tunnel without any installation .
Download Here - Click Here
wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64
After downloading this binary file we will give it executable permission with this command.
chmod +x filename
