Exposing HTTP’s Services

$ ngrok http 8080

Then, you can see the ngrok UI in your terminal, for example:

ngrok by @inconshreveable
 
Tunnel Status           online
Version                 2.2.8
Web Interface           http://127.0.0.1:4040
Forwarding              http://92832de0.ngrok.io  -> localhost:8080
Forwarding              
https://92832de0.ngrok.io -> localhost:8080 
Connnections            ttl     opn     rt1     rt5     p50     p90
                        0       0       0.00    0.00    0.00    0.00

In this example, you can access to your service (localhost:8080) through https://92832de0.ngrok.io Sure, https it’s hot to go!

Now, you can access to your localhost from anywhere, including the International Space Station (ISS).

Awesome, right?

What, are you using Virtual Hosts? Not problem.

You just need include the host-header flag:

$ ngrok http -host-header=myservice.local.vh port

For example, if I wanna expose this virtual host: f1soft.local.vh:80

$ ngrok http -host-header=jotarios.local.vh 80
