Salt Provisioner

Provisioner name: salt

The salt Provisioner allows you to provision the guest using Salt states.

Salt states are YAML documents that describes the current state a machine should be in, e.g. what packages should be installed, which services are running, and the contents of arbitrary files.

Masterless Quickstart

What follows is a basic Vagrantfile that will get salt working on a single minion, without a master:

  Vagrant.configure("2") do |config|
    ## Choose your base box
    config.vm.box = "precise64"

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

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

      salt.minion_config = "salt/minion"
      salt.run_highstate = true

    end
  end

This sets up a shared folder for the salt root, and copies the minion file over, then runs state.highstate on the machine. Your minion file must contain the line file_client: local in order to work in a masterless setup.

Install Options

  • install_master (boolean) - Should vagrant install the salt-master on this machine

  • no_minion (boolean) - Don't install the minion, default false

  • install_syndic (boolean) - Install the salt-syndic, default false

  • install_type (stable | git | daily | testing) - Whether to install from a distribution's stable package manager, git tree-ish, daily ppa, or testing repository.

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

  • always_install (boolean) - Installs salt binaries even if they are already detected, default false

Minion Options

These only make sense when no_minion is false.

  • minion_config (string, default: "salt/minion") - Path to a custom salt minion config file.

  • minion_key (string) - Path to your minion key

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

Master Options

These only make sense when install_master is true.

  • master_config (string, default: "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

  • seed_master (dictionary) - Upload keys to master, thereby pre-seeding it before use. Example: {minion_name:/path/to/key.pub}

Execute States

Either of the following may be used to actually execute states during provisioning.

  • run_highstate - (boolean) Executes state.highstate on vagrant up. Can be applied to any machine.
  • run_overstate - (boolean) Executes state.over on vagrant up. Can be applied to the master only.

Output Control

These may be used to control the output of state execution:

  • colorize - (boolean) Should output be colorized? Defaults to nil.

  • log_level - (One of all, garbage, trace, debug, info, warning, error, quiet) How verbose should the output be? Defaults to debug.

Pillar Data

You can export pillar data for use during provisioning by using the pillar command. Each call will merge the data so you can safely call it multiple times. The data passed in should only be hashes and lists. Here is an example::

      config.vm.provision :salt do |salt|

        # Export hostnames for webserver config
        salt.pillar({
          "hostnames" => {
            "www" => "www.example.com",
            "intranet" => "intranet.example.com"
          }
        })

        # Export database credentials
        salt.pillar({
          "database" => {
            "user" => "jdoe",
            "password" => "topsecret"
          }
        })

        salt.run_highstate = true

      end

Preseeding Keys

Preseeding keys is the recommended way to handle provisiong using a master. On a machine with salt installed, run salt-key --gen-keys=[minion_id] to generate the necessary .pub and .pem files

For a an example of a more advanced setup, look at the original plugin.
