Build From Tarball

Module that takes a path to a git archive tarball and uses heroku-style buildpackg to build the repo into a docker image.

NPM Dependency Status

Requirements

You will need the following installed. To get started you can use the supplied vagrant file which automatically installs docker and node.js on startup

Docker

The docker daemon must be installed and running. Visit https://docker.io for instructions on installing docker

Buildstep base image

A valid buildstep base docker image must be available in the list of docker images. There is an image available in the public docker index that will work if you do not wish to build your own

docker pull nisaacson/buildstep
 
# optionally tag this image with your own name 
# docker tag nisaacson/buildstep foo_buildstep 

Installation

npm install -S build-docker-image-from-tarball

Usage

Specfiy the following

  • sourcePath: /path/to/git/archive.tar.gz
  • buildImageName: buildstep base image that containers the builder script and heroku buildpacks
  • repo foo the name of the image that will be built and appear in docker images once the build completes
var buildFromTarball = require('build-from-tarball')
var data = {
  sourcePath: '/path/to/git/archive.tar.gz',
  buildImage: 'foo_buildstep',
  destImageName: 'foo_app'
}
 
buildFromTarball(data, function(err) {
  if (err) {
    console.dir('failed to build docker image from git archive tarball', err)
    return
  }
  console.log('image built correctly. You should now see the image %s when you execute `docker images`', data.destImageName)
})

Since the build progress is quite long, you may wish to monitor the progress of the build as it progresses. To monitor the progress, the builder is an instance of EventEmitter that emits log events instead of spamming stdout.

var Builder = require('build-from-tarball')
var data = {
  sourcePath: '/path/to/git/archive.tar.gz',
  buildImage: 'foo_buildstep',
  repo: 'foo_app'
}
var builder = new Builder()
 
// emit log events to avoid spamming stdout
builder.on('log', function(log) {
  console.dir(log)
})
 
builder.build(data, completeHandler)
