chisel-tunnel

Download releases of jpillora/chisel, a tool to create tcp-tunnels.

Chisel is a software written in Go that starts TCP-tunnels. It is a single binary that can be downloaded and started.

• As a server, it will listen on a port for incoming connections.
• As a client, it will connect to a chisel server and open a tunnel, similar to ssh port-forwarding.

The goal of this project is to download a specific version of chisel from the github-releases, matching your current architecture, in order to let you use it.

My specific goal is to use it as a reverse-tunnel to allow connections from a selenium-server to a local build-server in Gitlab-CI or docker-compose.

Such a reverse-tunnel can be achieved by running

chisel server -p 2222 --reverse

in the selenium docker-container. Then you can run

chisel client selenium:2222 R:6006:localhost:6006

to initiate the tunnel. Requests http://localhost:6006 on the selenium machine will then be forwarded to wherever you started your chisel client

Installation

npm install chisel-tunnel

Usage

The following example demonstrates how to use this module:

const chiselTunnel = require("chisel-tunnel");
const cp = require("child_process");
 
chiselTunnel.downloadChisel("~1.5.0").then(filename => {
  cp.spawnSync(filename, ["--version"], { stdio: "inherit" });
});

This will generate the following output

1.5.2
