= "hashicorp/precise64" config.vm.provision "shell", inline: "echo Hello World!" end
None
Commands • up • reload • provision • suspend •
resume • destroy [ --provision ] [ --provision ]
DEMO
Another Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.network :private_network,
ip: "192.168.33.101" config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end config.vm.synced_folder "./", "/vagrant", :nfs => true end

6.1 Debugging • Unknown Vagrant error – Use VirtualBox /
Vmware GUI • Unknown Provisioner error – Increase provisioner verbosity • Not working as expected – Login, fix, automate
6.2 Sync Folder Performance • Synchronization has a cost •
Framework cache/logs – Too much writing operations on disk – We don't need this in our synced folder
