How do I provision a Dockerfile from Vagrant

Question

How can I start the provisioning of Docker via an external Dockerfile? My Vagrantfile looks like this at the moment

Vagrant.configure("2") do |config|
  config.vm.box = "precise64"
  config.vm.define :server_infrastructure do |t|
  end

  config.vm.provision "docker" do |d|
    d.pull_images "ubuntu"
    #how does the below work?
    #d.build "new-container-name" "local-docker-file-name"
  end
end

Your help is greatly appreciated

Answer 1

An option for the Docker provisioner to build images was added in v1.6.0. Download the latest version from the Vagrant website.

Once you've done that, put a Dockerfile next to your Vagrantfile. Add this to your Vagrantfile:

config.vm.provision "docker" do |d|
  d.build_image "/vagrant", args: "-t my-name/my-new-image"
  d.run "my-name/my-new-image"
end

Now your Docker image will be built and run with vagrant up.

Answer 2

one workaround is through shell provisioning:

config.vm.provision "shell", inline: "docker build -t username/image /vagrant; docker run -d username/image"
