Vagrant - Provision (Code, Software Installation)

Code Shipping - Provisioning in Vagrant.

config.vm.provision :shell, path: "mydir/myScript.sh"

where:

• :shell is the provisioner
• mydir/myScript.sh is relative to the project directory

Provisioning happens at certain points during the lifetime of your Vagrant environment:

• On the first vagrant up that creates the environment, provisioning is run. If the environment was already created and the up is just resuming a machine or booting it up, they will not run unless the –provision flag is explicitly provided.
• When vagrant provision is used on a running environment.
• When vagrant reload –provision is called. The –provision flag must be present to force provisioning.
  • Reload quickly restart the virtual machine, skipping the initial import step.
  • –provision: instructs Vagrant to run the provisioners, since usually Vagrant will only do this on the first vagrant up.

You can also bring up your environment and explicitly not run provisioners by specifying –no-provision.

• In Vagrant - Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/precise64"
  config.vm.provision :shell, path: "installApache.sh"
end

• In the same directory than the Vagrant - Vagrantfile

#!/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
fi
