Root module exported from require('docker-process').

var DockerProcess = require('docker');
var dockerProc = new DockerProcess(
  // dockerode-promise instance
  docker,
  {
    // http://docs.docker.io/en/latest/api/docker_remote_api_v1.8/#create-a-container
    create: {},

    // http://docs.docker.io/en/latest/api/docker_remote_api_v1.8/#start-a-container
    start: {}
  }
);

event: exit

Emitted when docker container stops

event: close

Identical to exit

event: container

Emitted once the container is created (not running yet)

event: container start

Emitted once the container is started

dockerProc.stdout

Readable stream for stdout.

dockerProc.stderr

Readable stream for stderr.

dockerProc.id

Container id populated during run.

dockerProc.exitCode

Exit code populated after run.

dockerProc.run([options])

Pull the image from the docker index then create then start the container and return a promise for its exit status.

Options:

  • (Boolean) pull=true when false assume the image is cached.
dockerProc.run().then(

Example Usage

var DockerProcess = require('docker-process');
var dockerProc = new DockerProcess(
  // dockerode-promise instance
  docker,
  {
    // http://docs.docker.io/en/latest/api/docker_remote_api_v1.8/#create-a-container
    create: {
      Image: 'ubuntu',
      Cmd: ['/bin/bash', '-c', 'echo "xfoo"']
    },

    // http://docs.docker.io/en/latest/api/docker_remote_api_v1.8/#start-a-container
    start: {}
  }
);

dockerProc.run();

// a reference to the container can be obtained by waiting for the
// container event
dockerProc.once('container', function(container) {
});

dockerProc.stdout.pipe(process.stdout);
dockerProc.once('exit', function(code) {
  process.exit(code);  
})
