This is a fork project for ngrok, make its easier to use.

SECURITY ALERT

PLEASE READ THIS PARAGRAPH FIRST, VERY IMPORTANT !!!

To simplify the ngrok client build/usage, the tls verify logic will be skipped, so your traffic is in-secure, please DO NOT use this service to transfer sensitive/production data.

The server will generate a self-signed ssl cert as its tls encryption cert, and client will connect to server without ssl chain verify (but still transfer data under tls protection), in this solution, the users of self hosted service doesn't need to build the client/server again and again.

Client install & Usage

download binary from snapshot build

then start your tunnel with command

ngrok --serveraddr self_host_domain.com:4443 81

• the serveraddr is mandatory for your own server
  • format: self_host_domain:transfer_port, defaultly, the transfer port should be 4443
  • your service provider will tell you the serviceaddr
• the second parameter 81 is your local service port
  • format is same with serviceaddr
  • you can expose any services in your local network like 192.168.3.24:3000

another way: just run docker build -t ngrok -f client.Dockerfile . to build ngrok client image

Server setup

run following command in your server

docker run --name ngrokd -d --restart=always -p 4080:80 -p 4443:4443 -e DOMAIN=self_host_domain.com theosun/ngrok-fork

• you must create domain & sub-domain DNS records for your server firstly
  • self_host_domain.com -> your server ip
  • *.self_host_domain.com -> your server ip
• the DOMAIN environment variable is mandatory
  • DOMAIN env should be the root domain of your server, like self_host_domain.com
• port 4080, the http service port
• port 4443, the ngrok transfer port, the client users need to get this port to setup their tunnels
• setup reverse proxy for the ngrok http service port

Get a wildcard cert for your domain

(first of first, you should have your own domain)

just ref this doc

Server example reverse proxy config (for caddy server v1)

*.your_host_domain:443 {
  gzip
  proxy / http://127.0.0.1:4080 {
    transparent
    websocket
  }
  tls wildcardcertpath wildcardcertkeypath
}

for other server like nginx, you can find many many docs from search engine.
