vagrant dockerhost

This is a sample of a Vagrant Docker Provider configuration. It is based on ideas and samples from a comment by reddit user artsmeis. It uses dduportal/boot2docker-vagrant-box forked from yungsang/boot2docker, it appears that yungsang/boot2docker is no longer maintained.

Prerequisites

• Mac OS X
• Vagrant
• Virtualbox
• boot2docker

Sample Usage

using $HOME/projects/vagrant-dockerhost as the install location

$ cd $HOME/projects/vagrant-dockerhost
$ ./dockerenv
$ vagrant up
Bringing machine 'dockerhost' up with 'virtualbox' provider...

You should have some certs in the $HOME/projects/vagrant-dockerhost/tls directory now.

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

No container yet, but proves that the docker command can talk to the Virtualbox hosted docker.

Environment Variables

I recommend setting environment variables for the location of your docker host Vagrantfile.

sample contents of ~/.bash_profile replace $HOME/projects/vagrant-dockerhost with actual location.

export VAGRANT_DOCKERHOST="$HOME/projects/vagrant-dockerhost"
export VAGRANT_DOCKERHOST_VAGRANTFILE="$VAGRANT_DOCKERHOST/Vagrantfile"    
export VAGRANT_DOCKERHOST_NAME="dockerhost"
source "$VAGRANT_DOCKERHOST/dockerenv"

Sample Vagrantfile use by another project

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANT_DOCKERHOST_NAME = ENV['VAGRANT_DOCKERHOST_NAME'] || 'dockerhost'
VAGRANT_DOCKERHOST_VAGRANTFILE = ENV['VAGRANT_DOCKERHOST_VAGRANTFILE'] || './VagrantfileHost'
VAGRANTFILE_API_VERSION = "2"
ENV['VAGRANT_DEFAULT_PROVIDER'] = 'docker'

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.synced_folder ".", "/vagrant", disabled: true

  config.vm.define "mongodb" do |mdb|
  
    mdb.vm.provider "docker" do |d|
      d.name = "mongodb"
      d.image = "mongo:3.0.0"
      d.ports = ["27017:27017"]
      d.has_ssh = false
      d.vagrant_machine = VAGRANT_DOCKERHOST_NAME
      d.vagrant_vagrantfile = VAGRANT_DOCKERHOST_VAGRANTFILE
    end
  
  end
  
end

sample usage

$ vagrant up
Bringing machine 'mongodb' up with 'docker' provider...

$ docker ps
