outline
if we try to explain Ansible, we need to make a book for it. however we don’t know Ansible perfectly and our level is not able to explain it. so we can’t introduce details about Ansible but we try to explain Ansible by how we use Ansible. simply Ansible is an automation tool for infrastructure. we can do automatically install or deploy by Ansible. in here we introduce how to install Ansible to vagrant.
this blog post is for people who installed virtualbox and vagrant. if you don’t install virtualbox and vagrant, see our previous blog - vagrant installation and usage
create virtual machine setting
execute below vagrant command to create virtual machine(guest system) setting.
vagrant init bento/ubuntu-16.04
after executing above vagrant command, you can see Vagrantfile file in the folder you executed it. below code is Vagrantfile contents without comment out(#).
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.box = "bento/ubuntu-16.04"
end
create and check virtual machine
execute below vagrant command to create virtual machine(guest syste).
vagrant up
execute below vagrant command to access virtual machine(guest system) after being created it.
vagrant ssh
configure Ansible installation
if you execute below command in virtual machine(guest system), you can know Ansible is not installed yet.
ansible --version
open and modify Vagrantfile like below.
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.box = "bento/ubuntu-16.04"
config.vm.provision "shell", inline: <<-SHELL
sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository --yes --update ppa:ansible/ansible
sudo apt-get install ansible --yes
SHELL
end
provision shell makes to upload and execute script in virtual machine(guest system). add Ansible installation script to vagrant provision shell.
install Ansible
execute below vagrant command in local machine(host systme).
vagrant provision
access virtual machine(guest system) again and check Ansible installed.
vagrant ssh
ansible --version
if Ansible is installed, you can see Ansible version like below.
ansible 2.7.2
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/home/vagrant/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/dist-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.12 (default, Dec 4 2017, 14:50:18) [GCC 5.4.0 20160609]
above process is we created virtual machine(guest system) without Ansible installation script in provision shell and added Ansible installation script to provision shell and executed vagrant command(vagrant provision) to install Ansible.
however, if you configure environment to other PC or reconfigure, you just need to execute vagrant up because your Vagrantfile already has Ansible installation script in provision shell.
execute below vagrant command to remove virtual machine(guest system) for test it.
vagrant destroy
execute below vagrant command to create virtual machine(guest system) again.
vagrant up
after creating, execute below vagrant command to access virtual machine(guest system).
vagrant ssh
execute below command to check Ansible is installed.
ansible --version
if Ansible is installed, you can see below on the screen.
ansible 2.7.2
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/home/vagrant/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/dist-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.12 (default, Dec 4 2017, 14:50:18) [GCC 5.4.0 20160609]

in here, we introduced how to install Ansible to vagrant by Vagrantfile. if Ansible masters saw this blog, maybe they say why do we need to install Ansible to vagrant? not local PC(host system)? normally people install Ansible to local machine(host system) and they use Ansible to configure the infrastructure for virtual machine(guest system) but windows OS doesn’t support Ansible yet so we decided to do above process. next blog, we will introduce how to use Ansible to configure development environment in virtual machine(guest system).
