docker-browser-server

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)

Spawn a new container

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

Expose filesystem

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 listing
  • PUT /files/{container}/{path} Write a new file with the http body
  • POST /files/{container}/{path} Create a new directory

Expose a http server

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.

Adventure time

Checkout maxogden/adventure-time for a complete client environment that integrates with docker-browser-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

Programmatic usage

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)
