Agent for term.js to talk to a Docker container TTY over a WebSocket

Installation

  git clone https://github.com/rancherio/console-agent
  cd console-agent
  npm install

Usage

Start up the agent on a docker host:

  ./agent.js [--port <num>] [--bind <ip address>] [--docker <url for docker API>] [--key <PEM-encoded string or path to JWT public key file>]

Create an exec request through the cattle API to get a JSON Web Token:

  curl -X POST 'http://cattle-host:8080/v1/containers/<container_id>?exec'

Response:

  {
    ...
  }

And connect a websocket to the host and port specified:

  var socket = new WebSocket('ws://<host>:<port>/?token=<JWT string>');
  var term  = new Terminal({ // from term.js
    cols: 80,
    rows: 24
  });

  term.on('data', function(data) {
    socket.send(btoa(data));
  });

  socket.onmessage = function(message) {
    term.write(atob(message.data));
  });

  socket.onclose = function() {
    term.destroy();
  }

  term.open();
