Setup Ubuntu 16.04 to be used with Vagrant and Virtualbox

Prepare Vagrant box with Ubuntu 16.04

We will use official box "ubuntu/xenial64" and modify it to work with Vagrant.

• Vagrantfile

Vagrant.configure(2) do |config|

  config.vm.box = "ubuntu/xenial64"

  config.vm.provider "virtualbox" do |vb|
    #   # Display the VirtualBox GUI when booting the machine
    #   vb.gui = true
    #
    #   # Customize the amount of memory on the VM:
    vb.memory = "1524"
  end


end

• run Virtual machine (VM)

vagrant up

• login to VM

vagrant ssh

Hostname

• fix hostname in /etc/hosts

127.0.0.1 ubuntu-xenial

This will fix error:

"sudo: unable to resolve host ubuntu-xenial

Rename interfaces

• login to VM (vagrant ssh)

• add (or modify) lines in /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0 net.ifnames=0 biosdevname=0 net.ifnames=0 biosdevname=0"
GRUB_CMDLINE_LINUX=" net.ifnames=0 biosdevname=0"

• or update using command:

# 
sudo sed -i "s/GRUB_CMDLINE_LINUX_DEFAULT=\"\(.*\)\"/GRUB_CMDLINE_LINUX_DEFAULT=\"\1 net.ifnames=0 biosdevname=0\"/" /etc/default/grub

sudo sed -i "s/GRUB_CMDLINE_LINUX=\"\(.*\)\"/GRUB_CMDLINE_LINUX=\"\1 net.ifnames=0 biosdevname=0\"/" /etc/default/grub

• update

sudo update-grub

• so we will have interface named 'eth1'

• reboot VM from the host

vagrant reload

Install python

• To use Ansible we need to install Python 2

sudo apt-get install python

Setup VM

Provision with Ansible

• Vagrantfile

Vagrant.configure(2) do |config|

  ...
  
 
  config.vm.provider "virtualbox" do |vb|
    #   # Display the VirtualBox GUI when booting the machine
    #   vb.gui = true
    #
    #   # Customize the amount of memory on the VM:
    vb.memory = "1524"
  end


  config.vm.provision "ansible" do |p|
    p.playbook = "playbook.yml"
    p.verbose        = true
    p.extra_vars =
        {
            var1: "value1",
            ..
        }
  end
  
end  

• Ansible playbook.yml

---
- hosts: all
  sudo: true

  tasks:
    # tasks here
    

hostname

• Ansible playbook.yml

---
- hosts: all
  tasks:
  
# base
#    - hostname: name={{hostname}}
    - lineinfile: dest=/etc/hosts regexp='ubuntu-xenial' line='127.0.0.1 ubuntu-xenial'       state=present
    - lineinfile: dest=/etc/hosts regexp='{{hostname}}' line='127.0.0.1 {{hostname}}' state=present
    - shell: sudo bash -c 'hostnamectl set-hostname {{hostname}}'

Setup network

Static IP

• we will add a new interface 'eth1' with static IP

• Vagrantfile

HOSTNAME = 'debugserver'
IP = "51.0.99.120"
NETWORK_MASK = "255.0.0.0"
NETWORK_GATEWAY = "51.0.0.1"


Vagrant.configure(2) do |config|

  ...
  
  # IP
  config.vm.network "public_network", auto_config: false, :bridge => "eth0", ip: "#{IP}"

  config.vm.provider "virtualbox" do |vb|
    #   # Display the VirtualBox GUI when booting the machine
    #   vb.gui = true
    #
    #   # Customize the amount of memory on the VM:
    vb.memory = "1524"
  end


  config.vm.provision "ansible" do |p|
    p.playbook = "playbook.yml"
    p.verbose        = true
    p.extra_vars =
        {
            machine: "main",
            public_ip: IP,
            public_mask: NETWORK_MASK,
            public_gateway: NETWORK_GATEWAY,
        }
  end
  
end
