This is a demo project using Vagrant, Ansbile and Docker. An Ansible playbook is used to build a Docker image, and then start a Docker container. The Docker container runs a Django app which is executed within the Vagrant VM. After successful launch, the django App can be accessed from the host machine via http://localhost:8000.

Download ubuntu, forward port 8000, and run the Ansible playbook
Vagrant.configure(2) do |config|
config.vm.box = "raring"
config.vm.box_url = "https://cloud-images.ubuntu.com/vagrant/raring/current/raring-server-cloudimg-amd64-vagrant-disk1.box"
config.vm.network :forwarded_port, host: 8000, guest: 8000
config.vm.provision "ansible" do |ansible|
ansible.verbose = 'vvv'
ansible.playbook = 'playbook.yml'
end
end
Update packages installed on the Vagrant machine, configure ansible role for docker_ubuntu, build the docker image and run it with port 8000
