kitchen-docker-vm

OSX w/ kitchen-docker + an ubuntu vm = <3 faster tests <3

This Vagrantfile launches an ephemeral vm that exposes a Docker api capable of running Chef test-kitchen kitchens directly from OSX via kitchen-docker.

Prereqs

• VirtualBox or VMware Fusion + Vagrant VMware connector
• Vagrant
• vagrant-omnibus
• vagrant-berkshelf
• Docker CLI installed on OSX

Installing the Docker client on OSX

Pull down a binary or build your own on OSX with Go. Either way the Docker CLI needs to be in your path on the OSX side.

Installing the Docker client on OSX from source

$ go get github.com/dotcloud/docker
$ cd $GOPATH/src/github.com/dotcloud/docker/
$ git checkout v0.6.6
$ cd docker && go install
$ $GOPATH/bin/docker

Installation notes

• The Docker versions must match between host & guest or this will not work.
• kitchen-docker expects Docker v0.6.6 at this point. Using an earlier version breaks kitchen operations.
• The Docker daemon does not run on OSX. The CLI is used for communication.
• If you get clang errors compiling Docker from source, override CC with gcc-4.2 (requires a brew install apple-gcc42).

Usage

bundle install
vagrant up
