Vagrant with Docker provider and Ansible provisioning

vagrant-docker-ansible.md

# Vagrantfile

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

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.provider "docker" do |d|
    d.build_dir = "./provisioning"
    d.has_ssh = true
    d.name = "vm-docker"
  end

  config.ssh.forward_agent = true

  config.vm.synced_folder ".", "/vagrant"

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "provisioning/playbook.yml"
    ansible.limit = 'all'
  end
end
```

Don't forget to run vagrant specifying the docker provider :

```
vagrant up --provider=docker
```

# Dockerfile

Basically you take a bare distro, add vagrant user and public key, and install openssh and python
