Vagrant machines can also be provisioned using Salt (http://www.saltstack.com). Salt is a combination of configuration management and system orchestration software. Salt relies on a master/minion architecture to enable configuration and control of large clusters of machines, but in this example, we will use masterless salt to provision a basic web server and develop our own salt states that define system configurations.
Compared to other configuration management provisioners, getting started with the Vagrant Salt provisioner is rather easy; the provisioner itself will check for the existence of the salt-call command. If the command does not exist in the Vagrant machine, the provisioner will bootstrap the environment without plugins or bootstrapping scripts.
In this example, we'll write a simple state to provision the apache2 web server and apply the state using masterless Salt to apply our state.
