build-docker-image-from-tarball v0.1.0

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.

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
• buildImage: foo_buildstep base image that containers the builder script and heroku buildpacks
• destImageName foo_app 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)
})
