Spawn and expose docker containers over http and websockets
npm install -g docker-browser-server
Running the above will expose a command line tool called docker-browser-server.
To run the server do
docker-browser-server docker-image-name --port 8080
Make sure you pulled docker-image-name from a docker registry first.
Running the above will start the server on port 8080
Visit http://localhost:8080 after to attach to a container using a web browser.
You can also pass --hostNetworking to run the containers in host network mode, meaning the network is not virtualized (may be necessary for p2p connections to work)
To spawn a new container create a websocket to the server and pipe it to a docker-browser-console instance
// using browserify
var docker = require('docker-browser-console')
var websocket = require('websocket-stream')
var container = docker()
var socket = websocket('ws://localhost:8080')
container.appendTo(document.body)
socket.pipe(container).pipe(socket)A demo interface is available if you simply visit http://localhost:8080 after starting the server
If you run expose-fs inside your container the containers file system will be exposed using the following rest api
GET /files/{container}/{path}Get a file or directory listingPUT /files/{container}/{path}Write a new file with the http bodyPOST /files/{container}/{path}Create a new directory
When you spawn a new container a special env var called $HOST will be set to a http address.
If you listen on port 80 inside the container all requests going to $HOST will be forwarded to this server.

The easiest way to create your own workshop is creating a new Dockerfile and inheriting from the mafintosh/docker-browser-adventure image. This will setup expose-fs and install node among other things
FROM mafintosh/docker-adventure-time
RUN npm install -g your-workshop-stuff
var server = require('docker-browser-server')
var s = server('mafintosh/dev')
s.on('spawn', function(container) {
console.log('spawned new container', container.id)
})
s.on('kill', function(container) {
console.log('killed container', container.id)
})
s.listen(8080)MIT
