Problem Statement / Requirements:
(1) I need to establish a docker environment in a VirtualBox VM for testing a project.
(2) Boot2Docker and other pre-baked docker environments are great but they do not allow me to specialize the virtual machine for my specific needs.
(3) Sometimes testing can damage the virtual machines and snapshots have a heavy performance cost. Therefore, any solution I build needs to be reproducible through automation.
Solution:
(1) The following Vagrantfile will create a fresh vm and network
# Docker VM Builder # scaldwell@atlassian.com <Sam Caldwell> # require 'json' curr_dir = File.dirname(File.expand_path(__FILE__)) json = File.read("#{curr_dir}/Vagrantfile.json") global = JSON.parse(json) Vagrant.require_version global["api_require_version"] Vagrant.configure(global["api_version"]) do |config| config.vm.provider :virtualbox do |vb| vb.gui = global['vb_gui'] end config.vm.box = global['box'] config.vm.hostname="charlie-docker" config.ssh.guest_port=22 config.vm.boot_timeout = global['boot_timeout'] config.vm.provider :virtualbox do |v| v.customize ["modifyvm", :id, "--memory", global['ram']] v.customize ["modifyvm", :id, "--cpus", global['cpu']] v.customize ["modifyvm", :id, "--natdnshostresolver1", global['natdnshostresolver1']] v.customize ["modifyvm", :id, "--natdnsproxy1", global['natdnsproxy1']] end docker_host="tcp://#{global['docker_host']}" config.vm.network "private_network", virtualbox__intnet: global['network'], ip:global['ip_addr'] config.vm.network "forwarded_port", guest: 2376, host: 2376 config.vm.provision "shell", inline: <<-SHELL # # Configure hostfiles to use local squid proxy. # export DEBIAN_FRONTEND=noninteractive sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9 sudo su -l -c "echo deb https://get.docker.com/ubuntu docker main >> /etc/apt/sources.list.d/docker.list" sudo apt-get update --fix-missing -y sudo apt-get upgrade -y sudo apt-get install docker.io -y sudo apt-get install lxc-docker-1.5.0 -y sudo apt-get install lxc-docker -y echo export DOCKER_HOST="\\"#{global['docker_host']}\\"" > ~/docker.sh sudo mv ~/docker.sh /etc/profile.d/docker.sh sudo chmod +x /etc/profile.d/docker.sh sudo bash -c "echo 'DOCKER_OPTS=\\"--host #{global['docker_host']}\\"'>>/etc/default/docker" service docker restart SHELL end
(2) Note that this Vagrantfile works to abstract code from data by importing a JSON file called Vagrantfile.json. This keeps things clean and portable. The contents of the JSON file are--
{ "api_version": "2", "api_require_version":">= 1.6.0", "box": "ubuntu/trusty64", "vb_gui": false, "cpu":4, "ram":4096, "docker_host":"192.168.40.2:2376", "ip_addr":"192.168.40.2", "net_addr":"192.168.40.0/24", "network": "private_network", "natdnshostresolver1":"on", "natdnsproxy1":"on", "ssh_port": "22", "boot_timeout": 600 }
