Vagrant Ansible provisioning SSH error

Question

I'm trying to do some Vagrant/Ansible stuff, but running into problems from the start. Here's my Vagrantfile:

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

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"

  config.vm.network "private_network", ip: "192.168.6.66"

  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "site.yml"
  end
end

site.yml is simply

---
- name: Bring up server with MySQL, Nginx, and PHP-FPM
  hosts: all
  remote_user: root

  roles:
    - common

and common/tasks/main.yml is

---
- name: Update apt
  apt: update_cache=yes

When doing vagrant up, the output is

If I look at .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory, I see the following:

default ansible_ssh_host=127.0.0.1 ansible_ssh_port=2200

I would expect the IP there to be the same as set in the private_network? I've been staring at this for over an hour, did I do something wrong? I have a feeling the IP isn't being set properly or something. I can ping 192.168.6.66.

The problem here that your site.yml overrides the remote user ansible will use to root. But, you do not provide the private key for it, nor password.

So the way, I fixed it was to set ansible_ssh_user to "vagrant", because it is default known user, and ansible will behave the same as vagrant ssh if remote_user is not overriden. And set sudo true, because "vagrant" user is sudoer, but not su.

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

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"

  config.vm.network "private_network", ip: "192.168.6.66"

  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "site.yml"
    ansible.extra_vars = { ansible_ssh_user: 'vagrant' }
    ansible.sudo = true
    #ansible.verbose = 'vvvv'
  end
end
