A Docker image for ngrok, introspected tunnels to localhost. The image is built using progrium/busybox to keep the footprint as small as possible.
The container will tunnel either HTTP or HTTPS traffic by using the HTTPS_PORT or HTTP_PORT environment variables. Either environment variable can be set using the -e flag when running an ngrok container or by using linked containers, which is shown below.
This image is hosted on the Docker index as a trusted build and can be pulled down with:
docker pull fnichol/ngrok
We'll set up a simple HTTP server in a docker container called www:
docker run -v /www --name www_data busybox true
docker run --rm --volumes-from www_data busybox \
/bin/sh -c 'echo "<h1>Yo</h1>" > /www/index.html'
docker run -d -p 80 --volumes-from www_data --name www fnichol/uhttpd
Now we'll link the HTTP server container into an ngrok container to expose the server on the internet:
docker run -d -p 4040 --link www:http --name www_ngrok fnichol/ngrok
To get the *.ngrok.com address, check the container's logs:
docker logs www_ngrok
The ngrok web inspection interface is running on port 4040. To get the exposed port:
docker port www_ngrok 4040

Pull requests are very welcome! Make sure your patches are well tested. Ideally create a topic branch for every separate change you make. For example:
- Fork the repo
- Create your feature branch (
git checkout -b my-new-feature) - Commit your changes (
git commit -am 'Add support for feature') - Push to the branch (
git push origin my-new-feature)
