dockerode-build

Build a docker container using streams and Dockerode.

Install

npm i dockerode-build --save

Usage

'use strict'

var build = require('dockerode-build')
var path = require('path')
var pump = require('pump')

pump(
  build(path.join(__dirname, 'fixture', 'Dockerfile')),
  process.stdout,
  function (err) {
    if (err) {
      console.log('something went wrong:', err.message)
      process.exit(1)
    }
  }
)

API

dockerodeBuild(path[, opts])

Start a building stream from the given path to a Dockerfile. If the path is not absolute, it is resolved against process.cwd().

It returns a stream, that can be piped to the output destination.

If that stream is piped to a TTY, such as a process.stdout, the download progress bar will be automatically show, exactly like docker build ..

The opts are passed straight to dockerorde.buildImage(). If you add a docker opts, that would be used to instantiate the Dockerode instance with the given options (you would need this for auth).

Events:

• complete: building the image is complete, and the image id is the first argument.
• downloadProgress: emits the metadata returned by Docker to show the progress bars.
