How to debug the creation of docker container container in Vagrant

Question

I am trying out a basic example of running a container in a vagrant docker host. For this I created

The Dockerfile:

FROM ubuntu
#Other instructions

The Vagrantfile

 Vagrant.configure("2") do |config|
  config.vm.provider "docker" do |d|
   d.build_dir =  "."
   d.has_ssh = true
   d.name = "vagrant-docker-test"
 end
end

When I run vagrant up it creates a virtualbox with the docker-host and a docker container with state -preparing. When I try to see all running containers in the docker host I see none. Is tehre a way to debug if the creation of container failed?

Answer 1

I also had difficulties working on Dockerfile with the Vagrant Docker provider. In the end I now use a different approach: I use vagrant to run a Ubuntu VM on which Docker is installed ; and I use docker-compose to build and run the containers.

This way I can get a shell in the Ubuntu vm and run docker build at will.

Here's the Vagrantfile I use to get that Docker enabled Ubuntu VM. Also take a look at this answer I made earlier which is related to the subject.
