docker-mock

docker-mock

A mock for Docker!

Usage

Require it from your node program:

var dockerMock = require('docker-mock');
dockerMock.listen(5354);

You can also use the command line interface, just run docker-mock after installing the package globally.

Examples

See the tests for some sample usage, but you should be able to point your docker client at this mock and test against it.

Failures

This does have support for simulating failures during build. This is done (using dockerode) by doing the following:

// file is a tar containing at minimum a Dockerfile
var file = ...;
docker.buildImage(
  file,
  {
    t: 'doomedImage',
    fail: true
  },
  function (err, res) {
    // err will not be null
  });

Configuration

If you want to disable randomly generated events exposed under /events endpoint please use ENV var: DISABLE_RANDOM_EVENTS=true.

Events

You can manually emit docker mock events.

  var dockerMock = require('docker-mock');
  dockerMock.listen(5354);
  dockerMock.events.stream.emit('data', JSON.stringify({ status: 'die', from: '..', id: '...', time: '...' }));
  // or
  dockerMock.events.stream.emit('data', dockerMock.events.generateEvent());

Contributing

Please make sure all unit tests pass, lint passes, and coverage remains high during development (see below for details).

Testing

Testing is done locally via npm test.

Coverage

Coverage is now run by Lab via npm test. Output at the bottom shows percent coverage verses a threshold set in package.json.
