Steps & My Configs

1. Install virtualbox and vagrant on OS
2. In project build basic Vagrantfile (ruby) and install salt:

# -*- mode: ruby -*-
# vi: set ft=ruby :

$script = <<-SCRIPT
echo I am provisioning...
date > /etc/vagrant_provisioned_at
wget -O bootstrap-salt.sh https://bootstrap.saltproject.io
sudo sh bootstrap-salt.sh
SCRIPT

Vagrant.configure("3") do |config|
  config.vm.box = "ubuntu/focal64"
  config.vm.provision "shell", inline: $script
end

Issues

I kept running into an error with key provisioning. I want a salt master, to mirror my current live environment, and in my case I want the master to have a minion; but during configurations was getting this error:

$ vagrant destroy master                                                 
==> bots: Forcing shutdown of VM...
==> bots: Destroying VM and associated drives...
There are errors in the configuration of this machine. Please fix
the following errors and try again:      

salt provisioner:                              
* You must accept keys when running highstate with master!

It was quite frustrating because the error doesn’t clearly state what option(s) is missing. Looking around in the provisoiner code I found where the error is generated from:

https://github.com/hashicorp/vagrant/blob/a7135c000b55fbc2a346baf1dbf8169beedccf0f/plugins/provisioners/salt/config.rb#L163C1-L165

The options all need to work in conjunction: if @install_master && !@no_minion && !@seed_master && @run_highstate

   salt.install_master⋅=⋅true                                                
   salt.minion_config⋅=⋅"salt_minion/files/vagrant_minion.conf"              
   salt.run_highstate⋅=⋅true                                                 
   salt.seed_master⋅=⋅{          
     "salt-master" => "keys/master_minion.pem"                                            
	 "bots"⋅=>⋅"keys/bots.pem"                                               
   }   

You must pre-seed minion keys onto the master using the seed_master option, and include a dict of keys (instance names) with values (pem keys) of the path to the respective key.

In addition to that, since the master is running a local minion I need to give it it’s own config to start up properly. Using the salt.master_config & salt_minion_config options and giving both paths to respective, basic, configs.

$ cat salt_minion/files/vagrant_minion.conf 
master: 192.168.56.10
hash: sha256
$ cat salt_master/files/vagrant_master.conf 
auto_accept: True
$
