Vagrant Ansible provisioning SSH error - vagrant

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.

Answer 1

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
Please refer to the "WHY DOES THE ANSIBLE PROVISIONER CONNECT AS THE WRONG USER?" section Ansible Provisioning of Vagrant Documentation

Answer 2

Vagrant will create it's own ansible inventory file (which you've seen) with the defaults of 127.0.0.1 and 2200.
You need to specify the ansible inventory file using ansible.inventory_path
A very simple inventory file for use with Vagrant might look like:
default ansible_ssh_host=192.168.111.222 Where the above IP address is
one set in your Vagrantfile:
config.vm.network :private_network, ip: "192.168.111.222"
From https://docs.vagrantup.com/v2/provisioning/ansible.html

I had Ansible on Vagrant 1.7 trying to connect as root, probably because of some separate deployment repo group vars defaults. Possible fixes:
set ansible.force_remote_user = true or ansible_ssh_user extra/host/group vars appropriately
or move to Vagrant 1.8, which forces remote user by default, as per the changelog

Answer 4

I was having a similar problem, where it wouldn't ssh into the server for whatever reason for provisioning.
vagrant ssh worked fine, but vagrant provision would fail to ssh, due to a timeout.
I finally connected the dots and realized that this was actually because of the VPN client that my employer has us use. Cisco AnyConnect VPN client does some kind of buggery and makes it so that I have to restart my entire workstation to be able to run it.
Luckily, I don't have to be connected to a VPN for many things, so this only happens sporadically for me.
