docker.io

docker.io

Node.JS wrapper for low-level Docker.io HTTP interface

Usage

Using unix sockets (most secure)

// Sockets are used by default.
var docker = require('docker.io')({ socketPath: '/var/run/docker.sock' });

Using TCP connection

// You must specify socketPath: false to indicate you want to use TCP connections.
var docker = require('docker.io')({ socketPath: false, host: 'http://localhost', port: '4243'});

The defaults for the connection options are:

• socketPath: /var/run/docker.sock
• host: http://localhost
• port: 4243

API calls

Here is an example API call, more examples can be found here

var options = {}; // all options listed in the REST documentation for Docker are supported.

docker.containers.list(options /* optional*/, function(err, res) {
    if (err) throw err;
    console.log("data returned from Docker as JS object: ", res);
});

API calls (w/streams)

//tty:true
docker.containers.attach('hi74y2i34yi23', {stream: true, stdout: true, stderr: true, tty: true}, function(err, stream) {
  stream.pipe(process.stdout);
});

//tty:false
docker.containers.attach('hi74y2i34yi23', ({stream: true, stdout: true, stderr: true, tty: false}, function(err, stream) {
  //http://docs.docker.io/en/latest/api/docker_remote_api_v1.7/#post--containers-(id)-attach
  docker.demuxStream(stream, process.stdout, process.stderr);
});

docker.image.create({fromImage: 'ubuntu'}, function(err, stream) {
  stream.pipe(process.stdout);
});

Changes

0.9.7

- A MAJOR issue was fixed where the wrong endpoints were being called. If you were using a 0.9.x version of docker.io already, you should upgrade ASAP!

0.9.3

- Uses docker-modem now for a better shared codebase with the community!
- Known issues: attach still needs to be updated for the new API

0.9.2

- Streams! APIs that have a streaming response, docker.io returns a Stream object now!
- Now has support for ALL API  endpoints
- Attach endpoint now works again
- Known issues: attach still needs to be updated for the new API
