TL;DR if you’re lucky and everything is installed right and you don’t want to understand deeper, try:
First, let’s install Vagrant on the host computer (a MacOS X Mavericks here, using Homebrew Cask that can install binary install packages):
Then let’s create a directory where we’ll store the Vagrant related file for this host:
mkdir vagrant-docker
And let’s create this “Vagrantfile” file to describe our new VM in the Vagrant language:
Vagrant.configure(“2”) do |config|
config.vm.box = “trusty”
config.vm.box_url = “https://cloud-images.ubuntu.com/vagrant/trusty/trusty-server-cloudimg-amd64-juju-vagrant-disk1.box”
# we’ll forward the port 8000 from the VM to the port 8000 on the host (OS X)
config.vm.network :forwarded_port, host: 8000, guest: 8000
config.vm.synced_folder(“vagrant-docker”, “/vagrant”)
# add a bit more memory, it never hurts. It’s VM specific and we’re using Virtualbox here.
config.vm.provider :virtualbox do |vb|
vb.customize [“modifyvm”, :id, “–memory”, 2048]
end
end
Now it’s done, we can create the VM:
$ vagrant up

If you have some problems about conflicting local host and guest ports, it’s ONE of the different Vagrantfile being used that may be the cause of your trouble: https://stackoverflow.com/questions/10953070/how-to-debug-vagrant-cannot-forward-the-specified-ports-on-this-vm-message/25142933#25142933
Watch out, your Vagrantfile is **not the only one** being used when bringing up a Vagrant box/instance.
When you get this:
~/dev/vagrant user$ vagrant reload
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 8001 is already in use
on the host machine.
To fix this, modify your current projects Vagrantfile to use another
port. Example, where ‘1234’ would be replaced by a unique host port:
config.vm.network :forwarded_port, guest: 8001, host: 1234
Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn’t allow modifying port forwarding.
~/dev/vagrant user$
You are actually not only using the Vagrantfile from ~/dev/vagrant but also the one from your “box” distribution .box file which is typically located here:
~/.vagrant.d/boxes/trusty/0/virtualbox/Vagrantfile
And if you have a look at it you’ll see it has plenty of **default** port mappings:
$ cat ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile
$script = <<SCRIPT
bzr branch lp:jujuredirector/quickstart /tmp/jujuredir
bash /tmp/jujuredir/setup-juju.sh
SCRIPT
Vagrant.configure(“2”) do |config|
# This Vagrantfile is auto-generated by ‘vagrant package’ to contain
# the MAC address of the box. Custom configuration should be placed in
# the actual ‘Vagrantfile’ in this box.
config.vm.base_mac = “080027DFD2C4”
config.vm.network :forwarded_port, guest: 22, host: 2122, host_ip: “127.0.0.1”
config.vm.network :forwarded_port, guest: 80, host: 6080, host_ip: “127.0.0.1”
config.vm.network :forwarded_port, guest: 8001, host: 8001, host_ip: “127.0.0.1”
config.vm.network “private_network”, ip: “172.16.250.15”
config.vm.provision “shell”, inline: $script
end
# Load include vagrant file if it exists after the auto-generated
# so it can override any of the settings
include_vagrantfile = File.expand_path(“../include/_Vagrantfile”, __FILE__)
load include_vagrantfile if File.exist?(include_vagrantfile)
So, go ahead and edit this file to remove the offending colliding forwarding port(s):
config.vm.network :forwarded_port, guest: 22, host: 2122, host_ip: “127.0.0.1”
config.vm.network :forwarded_port, guest: 80, host: 6080, host_ip: “127.0.0.1”
# config.vm.network :forwarded_port, guest: 8001, host: 8001, host_ip: “127.0.0.1”
By:
~/dev/vagrant user$ cp ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile.old
~/dev/vagrant user$ vi ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile
and watch out for other Vagrantfiles inclusion i.e.:
include_vagrantfile = File.expand_path(“../include/_Vagrantfile”, __FILE__)
And now it works:
$ vagrant up

Type then:
vagrant ssh
And you will be connected.
Enjoy your Vagrant install of Ubuntu Server 14.04 LTS (Trusty Tahr).
Packaged with this Ubuntu Server 14.04 LTS (Trusty Tahr), you will get Juju and Docker pre-installed. This will enable you to connect to http://127.0.0.1:8001 to access Juju web UI.
Update:
Then you want to run Docker. Two ways to do that:
- Run Docker from within Linux Ubuntu 14.04
- Run Docker from within Mac OS X with Boot2Docker
