A [Docker][docker] image for [ngrok][ngrok] v2, introspected tunnels to localhost.
It's based on the excellent work of [wizardapps/ngrok][wizardapps/ngrok] and [fnichol/ngrok][fnichol/ngrok].

## Features
2015-06-22 12:03:40 +00:00
2015-06-22 12:06:20 +00:00
* **Small**: Built using [busybox][busybox].
* **Simple**: Just link as `http` or `https` in most cases, see below; exposes ngrok server `4040` port.
2015-06-30 13:02:23 +00:00
* **Secure**: Runs as non-root user with a random UID `6737` (to avoid mapping to an existing UID).

## Usage
2015-06-30 13:02:23 +00:00
2015-07-07 13:08:44 +00:00
Supposing you've an Apache or Nginx Docker container named `web_service_container` listening on port 80:
2016-10-16 15:22:40 +00:00
$ docker run --rm -it --link web_service_container wernight/ngrok ngrok http web_service_container:80
2015-06-30 13:02:23 +00:00

2016-07-08 07:33:56 +00:00
### Environment variables
*Please consider using directly the command-line arguments of Ngrok.*
2016-07-08 09:35:19 +00:00
If you use the default `CMD` (i.e. don't specify the ngrok command-line but only `wernight/ngrok`),
then you can use instead envrionment variables magic below.
2016-07-08 07:33:56 +00:00
You simply have to link the Ngrok container to the application under the `app` or `http` or `https` aliases, and all of the configuration will be done for you by default.
Additionally, you can specify one of several environment variable (via `-e`) to configure your Ngrok tunnel:
* `NGROK_AUTH` - Authentication key for your Ngrok account. This is needed for custom subdomains, custom domains, and HTTP authentication.
* `NGROK_SUBDOMAIN` - Name of the custom subdomain to use for your tunnel. You must also provide the authentication token.
2017-03-16 23:52:33 +00:00
* `NGROK_HOSTNAME` - Paying Ngrok customers can specify a custom domain. Only one subdomain or domain can be specified, with the domain taking priority.
2016-07-08 07:33:56 +00:00
* `NGROK_USERNAME` - Username to use for HTTP authentication on the tunnel. You must also specify an authentication token.
* `NGROK_PASSWORD` - Password to use for HTTP authentication on the tunnel. You must also specify an authentication token.
* `NGROK_PROTOCOL` - Can either be `HTTP` or `TCP`, and it defaults to `HTTP` if not specified. If set to `TCP`, Ngrok will allocate a port instead of a subdomain and proxy TCP requests directly to your application.
* `NGROK_PORT` - Port to expose (defaults to `80` for `HTTP` protocol).
* `NGROK_REGION` - Location of the ngrok tunnel server; can be `us` (United States, default), `eu` (Europe), `ap` (Asia/Pacific) or `au` (Australia)

#### Full example
2015-06-22 12:03:40 +00:00
1. We'll set up a simple example HTTP server in a docker container named `www`:
$ docker run -v /usr/share/nginx/html --name www_data busybox true
$ docker run --rm --volumes-from www_data busybox /bin/sh -c 'echo "<h1>Yo</h1>" > /usr/share/nginx/html/index.html'
$ docker run -d -p 80 --volumes-from www_data --name www nginx
$ curl $(docker port www 80)
<h1>Yo</h1>
2. Now we'll link that HTTP server into an ngrok container to expose it on the internet:
$ docker run -d -p 4040 --link www:http --name www_ngrok wernight/ngrok
3. You can now access the [API][ngrok-api] to find the assigned domain:
$ curl $(docker port www_ngrok 4040)/api/tunnels
or access the web UI to see requests and responses:
$ xdg-open http://$(docker port www_ngrok 4040)
2016-06-29 05:55:26 +00:00
### Helper
For common cases you may want to create an alias in your `~/.profile` (or `~/.bashrc`, `~/.zshrc`, or equivalent):
function docker-ngrok() {
docker run --rm -it --link "$1":http wernight/ngrok ngrok http http:80
}
# For ZSH with Oh-My-Zsh! and 'docker' plugin enabled, you can also enable auto-completion:
#compdef __docker_containers docker-ngrok
Then to the simple example just do `docker-ngrok web_service_container`.
