CoreOS Packer

This is a packer template for CoreOS. The template currently supports only for Vagrant with Parallels images, but other builders will be added soon.

Getting Started with Vagrant and Parallels

1. Preparation

Install Homebrew

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Homebrew Cask

$ brew install caskroom/cask/brew-cask

Install Parallels Desktop & Virtualization SDK

You need an appropriate license to use Parallels Desktop & Virtualization SDK.

$ brew cask install parallels-desktop
$ brew cask install parallels-virtualization-sdk

Install Vagrant & Parallels Provider

$ brew cask install vagrant
$ vagrant plugin install vagrant-parallels

Install Packer

$ brew cask install packer

2. Build a Vagrant Box

$ git clone https://github.com/jgkim/coreos-packer.git
$ cd coreos-packer
$ packer build -var 'channel=stable' -var 'version=647.2.0' -var 'checksum=adef94fabf7c3573b37b35fc7cf7ff2c' coreos.json

3. Add the Box to Vagrant

$ vagrant box add --force --provider=parallels -name {name}/coreos-stable builds/stable/647.2.0/coreos_production_vagrant_parallels.box

4. Vagrant Up

$ vagrant init {name}/coreos-stable
$ vagrant up
$ vagrant ssh

Known Issues

• Building images fails from time to time due to coreos/bugs#152.
• Vagrant Cloud Post-Processor has some bugs in the latest release (0.7.5), but works properly with the recent code.
• There are bugs regarding use of only or except configurations in post-processors.
• The version description option in Vagrant Cloud Post-Processor is not interpolated with template variables.
• Atlas Post-Processor also works only with the development version of Packer, and it does not use the interpolation in metadata blocks.
