Ubuntu + Vagrant + docker无需使用Virtualbox即可撰写

Question

Hy,

I have been using Vagrant + Docker on Windows PC for a while, with Virtualbox. Since few weeks I have turned my mind toward Ubuntu 16.04 LTS, and started to migrate my Vagrant stuff on my new hardware.

Some of Vagrants were using docker-compose on my old PC. Now, on Ubuntu, I want to use Docker and Docker-compose directly, without Virtualbox. Certainly I could forget Vagrant and work directly with Docker compose, but I prefer to have every environnement monitored via Vagrant, to stay homogeneous.

I can't find information on how to use "docker compose" in this new context (Ubuntu 16 + Vagrant : prodiver = Docker and Provisionner = Docker compose).

Some link display the usage of "vagrant-docker-compose" plugin, but it dosen't work for me. I don't realy hunderstand why, but I think it's logical as I am using Docker directly on my machine, whitout VBox, and every example seems stating that your are using VBox.

Am I mistaking about the right way to solve my issue ?

Now my Vagrantfile looks like this (I tried other stuff...without any more success..):

Vagrant.configure(2) do |config|

  config.vm.provider "docker" do |docker|

    docker.image="ubuntu:16.04"
    docker.compose=true

  end

    config.vm.provision :docker

    config.vm.provision :docker_compose, rebuild: true, yml: "/direct/docker-compose.yml", run: "always"

end

But the docker-compose.yml isn't loaded....andd Vagrant says

"he container started either never left the "stopped" state or very quickly reverted to the "stopped" state. ..."

In fact : I don't understand where I must indicate the path to my docker-compose.yml file....

Could you help me ? Do you have a clue, or a link to a tuto ? Can you enlight my mind saoul about the right way to solve it .... :[

Regards :)

First, just to clarify that even though you are on Ubuntu and running Linux natively, the docker and docker_compose provisioners (I'm assuming from https://github.com/leighmcculloch/vagrant-docker-compose ) will still run inside the Vagrant VM. It is not using the native Docker on your host.

Next, the docker-compose.yml file that it is referencing is from inside the Vagrant machine. Usually, this is the shared folder for the project at /vagrant . In this case, assuming the docker-compose.yml file lives next to the Vagrantfile , the yml path should be /vagrant/docker-compose.yml .
