 Vagrant
=========

Changing Vagrant home directory
===============================

Set ``VAGRANT_HOME`` env var, like::

  VAGRANT_HOME=d:\srv\vagrant

Default is ``~/.vagrant.d`` for Linux and ``%USERPROFILE%\.vagrant.d`` for Windows.

Pointing to VirtualBox location
===============================

Set ``VBOX_MSI_INSTALL_PATH`` variable::

  VBOX_MSI_INSTALL_PATH=c:\opt\VirtualBox

It is set/updated by VirtualBox installer and was ``VBOX_INSTALL_PATH`` before 4.3.12 (2014).

Updating Vagrant
================

Plugins are required to reconfigures when Vagrant version was updated::

  vagrant plugin expunge --reinstall

and possibly::

  vagrant plugin update

Managing names
==============

Vagrant VM name::

  config.vm.define "NAME"

VirtualBox name::

  config.vm.provider :virtualbox do |vb|
    vb.name = "NAME"
  end

Host name::

  config.vm.hostname = "NAME"

Managing boxes
==============

Store new box from catalog locally::

  $ vagrant box add ubuntu/trusty64
  $ vagrant box add --provider virtualbox hashicorp/precise64

Check for box updates::

  $ cd $BOXDIR
  $ vagrant box outdated

or::

  $ vagrant box outdated --global

Disable checking for update each time you call ``vagrant`` command::

  Vagrant.configure("2") do |config|
    config.vm.box_check_update = false
  end

Download box update::

  $ vagrant box update

.. note::
   ``vagrant box update`` does not magicall updates your existing boxes. In just download
   updated versions. To install new versio you need to destroy and install new boxes::

     $ vagrant destroy
     $ vagrant up

To remove box at specific version::

  $ vagrant box remove laravel/homestead --box-version 1.1.0

To get list of boxes with corresponding versions::

  $ vagrant box list
  $ vagrant global-status

https://www.vagrantup.com/docs/cli/box.html
  Command: ``vagrant box``.

  Box Versioning.

Exporting boxes
===============

Any VirtualBox VM can be packages as Vagrant box. Find VM name or UUID with::

  $ VBoxManage list vms

Pass it to one of::

  $ vagrant package --base $VM_NAME
  $ vagrant package --base $VM_UUID
  $ vagrant package --base $VM_NAME --output my.box
  $ vagrant package --base $VM_UUID --output my.box

If you are in Vagrant managed directory (with ``.vagrant`` subdirectory) it is as simple as::

  $ vagrant package

.. note:: Only one VM is packages even if Vagrant file defines several VMs.

Import packages box::

  $ vagrant box add --name $NAME /path/to/new.box
  ...
  $ vagrant init $NAME
  ...
  $ vagrant up

To export box from local catalog::

  $ vagrant box list
  $ vagrant box repackage NAME PROVIDER VERSION

Debugging Vagrant
=================

Add environment variable::

  VAGRANT_LOG=warn vagrant ssh
  VAGRANT_LOG=info vagrant ssh
  VAGRANT_LOG=debug vagrant ssh

or option::

  vagrant up --debug

To add timestamps use one of::

  VAGRANT_LOG_TIMESTAMP=1 vagrant up
  vagrant up --timestamp

To add both as option::

  vagrant up --debug-timestamp

Running individual provisioning scripts
=======================================

You may give name to provisioning script::

  Vagrant.configure("2") do |config|
    config.vm.provision 'user_ssh', type: :shell, privileged: false do |s|
      ssh_pub_key = File.readlines("#{Dir.home}/.ssh/id_rsa.pub").first.strip
      s.inline = "echo #{ssh_pub_key} >> /home/$USER/.ssh/authorized_keys"
    end
    config.vm.provision 'root_ssh', type: :shell, privileged: true do |s|
      ssh_pub_key = File.readlines("#{Dir.home}/.ssh/id_rsa.pub").first.strip
      s.inline = "mkdir /root/.ssh/; echo #{ssh_pub_key} >> /root/.ssh/authorized_keys"
    end
    ...
  end

and apply them individually::

  vagrant provision --provision-with user_ssh
  vagrant provision --provision-with root_ssh
  vagrant provision --provision-with user_ssh,root_ssh

Copying files
=============

To copy files recursively to running box::

  vagrant upload $SRC $DST
  vagrant upload $SRC $DST  $BOXID

To copy to ``/home/vagrant``::

  vagrant upload $SRC .
  vagrant upload $SRC .  $BOXID

To copy to ``/home/vagrant/$DIR``::

  vagrant upload $SRC $DIR
  vagrant upload $SRC $DIR  $BOXID

https://www.vagrantup.com/docs/cli/upload.html
  Uploads files and directories from the host to the guest machine.

There is 3rd patry option with::

  vagrant plugin install vagrant-scp
  vagrant scp $SRC :$DST
  vagrant scp $SRC $BOXID:$DST

Working with Alpine Linux
=========================

Install plugin::

  $ vagrant plugin install vagrant-alpine
  Installing the 'vagrant-alpine' plugin. This can take a few minutes...
  Installed the plugin 'vagrant-alpine (0.3.0)'!

Create Vagrantfile::

  $ vagrant init maier/alpine-3.6-x86_64
