VM Provisioning with vagrant the ansible way

Requirements

• vagrant
• vagrant-virtualbox
• virtualbox

Vagrantfile

No modification should be needed to the Vagrantfile Vagrant loads the box and configures virtualbox

Create your own scenario

1. Create a value under children, this is the name of the scenario
2. adjust the name of the variable scenario
3. for all hosts in your scenario:
   1. copy paste the hostone directory under host_vars
   2. rename to your host names
   3. adjust to your needs, eg. memory and cpu
4. vagrant up --color --provision

hosts.yml

Variable	default	description
scenario	dev	The name for your scenario. You can have multiple scenarios
group	dev	create a group and put all hosts which should be setup in this group
hosts	hostone	host to create. Multiple values allowed

Scenarios

You can have different scenarios in the same directory.

all:
  vars:
    scenario: kubernetes
  children:
    dev:
      hosts:
        hostone:
    kubernetes:
      hosts:
        workerone:
        workertwo:
        master:

When scenario: kubernetes is set, vagrant only recognizes hosts workerone, workertwo and master. vagrant up creates these hosts

With scenario: dev set, all vagrant sees is hostone. vagrant up only creates hostone.

When using this keep in mind in which scenario you are operating. Otherwise vagrant destroy could break your setup.

inventory/host_vars/host/vagrant.yml

This file should be inside a directory named like the host to be created. See subsection name for example.

Variable	default	description
ansible_user	"vagrant"	This is the user which vagrant uses to connect to the host and run its blobs. Should initially set to vagrant
box	"ubuntu/focal64"	Vagrant box to use
synced_folder	"sync/"	folder to sync
hostname:	"foobar"	hostname
gui:	false	When gui is true for hyperv files/install_xrdp.sh is executed
customize_opts	truncated see host_vars/hostone/vagrant.yml	customization options for virtual box see VBoxManage --help for an overview
forwarded_port	truncated see host_vars/hostone/vagrant.yml	Ports to forward
file_provision	truncated see host_vars/hostone/vagrant.yml	Files to provision
shell_provision	truncated see host_vars/hostone/vagrant.yml	Shell scripts to run on host

Execution

1. Creates VM in virtualbox
2. File provsioning
3. shell execution
4. preinstall.sh | bash
5. ansible execution

preinstall.sh

Changes vagrant user password to vagrant Install ansible NOTE: change password

ansible play

Vagrant executes the ansible playbook converge.yml Adjust this to your needs. Vagrant also installs all the needed roles (if one). So update the requirements.yml.

ssh config

vagrant ssh-config 2>/dev/null >> ~/.ssh/config
ansible -m ping -i inventory/hosts.yml kubernetes

Windows networking

Create bridge interface

New-VMSwitch -Name Internet -NetAdapterName <your online NetAdapter> -AllowManagementOS $true
## Set trunk mode on VSwitch
