Attach subdomains to ngrok tunnels

Attach custom domain to ngrok tunnel

Ngrok is an awesome tool which let you expose port on your local machine to the internet. Ngrok gives you a random hostname for each tunnel.

This tool enables you to attach subdomains against those tunnels.

Currently supported DNS includes GoDaddy only.

Build and install from source

This requires Golang to be installed

$ go get -v github.com/alyyousuf7/ngrok-custom-domain/cmd/ngrokcd

Usage

ngrokcd requires ngrok to be already running.

ngrokcd can be used in three different ways mentioned below.

Attach a single subdomain to the first tunnel

This is useful if you expose only one tunnel to the internet using ngrok http 8080 and wish to have a subdomain against it.

$ ngrokcd attach-first [subdomain] [domain] [service=godaddy] [key] [secret]

Attach a single subdomain to a specific tunnel

This is useful if you expose only one tunnel to the internet using ngrok configuration file and wish to have a subdomain against it.

In ngrok configuration, you mention a tunnel name. In the following configuration, it is mytunnel.

authtoken: [your ngrok authtoken]
tunnels:
  mytunnel:
    proto: http
    addr: 8080

$ ngrokcd attach [ngrok tunnel name] [subdomain] [domain] [service=godaddy] [key] [secret]

Attach multiple subdomains to a number of tunnels

This is useful if you expose multiple tunnels to the internet and wish to attach subdomains to couple of them.

You must have already used ngrok configuration file to expose them. For example you have the following tunnels:

authtoken: [your ngrok authtoken]
tunnels:
  api:
    proto: http
    addr: 4000
  web:
    proto: http
    addr: 8080

Now to attach one subdomain to api and two subdomains to web, you have to modify the configuration file (~/.ngrok2/ngrok.yml) to something like this:

authtoken: [your ngrok authtoken]
tunnels:
  api:
    proto: http
    addr: 4000
    records:
    - myapp-api
  web:
    proto: http
    addr: 8080
    records:
    - myapp-app
    - myapp-www
records:
  myapp-api:
    dns: personal-domain
    cname: api
  myapp-app:
    dns: personal-domain
    cname: app
  myapp-www:
    dns: personal-domain
    cname: www
dns:
  personal-domain:
    domain: aliyousuf.com
    service: godaddy
    key: [godaddy api key]
    secret: [godaddy api secret]
