Introduction

Salty Vagrant_ is a plugin for Vagrant which lets you use salt as a provisioning tool. You can use your existing salt formulas and configs to build up development environments.

.. _Salty Vagrant: https://github.com/saltstack/salty-vagrant

The simplest way to use Salty Vagrant_ is by configuring it for masterless mode. With this setup, you use a standalone minion along with your file_roots and/or pillar_roots. See the examples/ folder for more details.

Masterless (Quick Start)

  1. Install Vagrant_
  2. Install Salty Vagrant_ (vagrant plugin install vagrant-salt)
  3. Get the Ubuntu 12.04 base box: vagrant box add precise64 http://files.vagrantup.com/precise64.box
  4. Create/Update your Vagrantfile (Detailed in Configuration_) [#shared_folders]_
  5. Place your minion config in salt/minion [#file_client]_
  6. Run vagrant up and you should be good to go.

.. [#file_client] Make sure your minion config sets file_client: local for masterless .. [#shared_folders] Don't forget to create a shared folder for your salt file root

Configuration

Here is an extremely simple Vagrantfile, to be used with

the above masterless setup
Vagrant.configure("2") do |config|
  ## Chose your base box
  config.vm.box = "precise64"

  ## For masterless, mount your salt file root
  config.vm.synced_folder "salt/roots/", "/srv/"

  ## Use all the defaults:
  config.vm.provision :salt do |salt|

    salt.run_highstate = true

  end
end

Actions

run_highstate (true/false) Executes state.highstate on vagrant up

accept_keys (true/false) Accept all keys if running a master

Install Options

install_master (true/false) Install the salt-master

no_minion (true/false) Don't install the minion

install_syndic (true/false) Install the salt-syndic

install_type (stable | git | daily) Whether to install from a distribution's stable package manager, a daily ppa, or git treeish.

install_args (develop) When performing a git install, you can specify a branch, tag, or any treeish.

always_install (true/false) Installs salt binaries even if they are already detected

Minion Options

minion_config (salt/minion) Path to a custom salt minion config file.

minion_key (salt/key/minion.pem) Path to your minion key

minion_pub (salt/key/minion.pub) Path to your minion public key

Master Options

master_config (salt/minion) Path to a custom salt master config file

master_key (salt/key/master.pem) Path to your master key

master_pub (salt/key/master.pub) Path to your master public key

Other

bootstrap_script (salt/bootstrap_salt.sh) Path to a custom bootstrap_ script

temp_config_dir (/tmp) Path on the guest box that config and bootstrap files will be copied to before placing in the salt directories

verbose (true/false) Prints bootstrap script output to screen

Miscellaneous

Using Remote Salt Master

If you are already using Salt_ for deployment, you can use your existing master to provision your vagrant boxes as well. You will need to do one of the following:

#. Manually accept the vagrant's minion key after it boots. [#accept_key]_ #. Preseed the Vagrant box with minion keys pre-generated on the master

.. [#accept_key] This is not recommended. If your developers need to destroy and rebuild their VM, you will have to repeat the process.

Preseeding Vagrant Minion Keys

On the master, create the keypair and add the public key to the accepted minions

folder
root@saltmaster# salt-key --gen-keys=[minion_id]
root@saltmaster# cp [minion_id].pub /etc/salt/pki/master/minions/[minion_id]

Replace [minion_id] with the id you would like to assign the minion.

Next you want to bundle the key pair along with your Vagrantfile, the salt_provisioner.rb, and your minion config. The directory should look

something like this
myvagrant/
    Vagrantfile
    salt/
        minion.conf
        key/
            minion.pem
            minion.pub

You will need to determine your own secure method of transferring this package. Leaking the minion's private key poses a security risk to your salt network.

The are two required settings for your minion.conf file
master: [master_fqdn]
id: [minion_id]

Make sure you use the same [minion_id] that you used on the master or it will not match with the key.

Create/Update your Vagrantfile per the example provided in the Configuration_ section.

Finally, you should be able to run vagrant up and the salt should put your vagrant minion in state.highstate.
