Add a box: vagrant box add hashicorp/precise32

end

$ ls /vagrant• default synced folder

$ vagrant destroy

Up and Running

• Supported provisioning types: • file, shell, Chef, Puppet, Ansible, Salt, Docker

• Example: Installing Apache bootstrap.sh :

Vagrantfile:

Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise32" config.vm.provision :shell, path: "bootstrap.sh" end

#!/usr/bin/env bash apt-get update

apt-get install -y apache2 if ! [ -L /var/www ]; then

rm -rf /var/www ln -fs /vagrant /var/www
