3.1.1. Salt Masterless Quickstart

Running a master-less salt-minion lets you use Salt's configuration management for a single machine without calling out to a Salt master on another machine.

It is also useful for testing out state trees before deploying to a production setup.

The only real difference in using a standalone minion is that instead of issuing commands with salt, the salt-call command is used instead:

salt-call --local state.highstate Bootstrap Salt Minion

The salt-bootstrap script makes boostrapping a server with Salt simple for any OS with a Bourne shell:

wget -O - http://bootstrap.saltstack.org | sudo sh

See the salt-bootstrap documentation for other one liners. When using Vagrant to test out salt, the salty-vagrant tool will provision the VM for you. Create State Tree

Following the successful installation of a salt-minion, the next step is to create a state tree, which is where the SLS files that comprise the possible states of the minion are stored.

The following example walks through the steps necessary to create a state tree that ensures that the server has the Apache webserver installed.

  1. Create the top.sls file:


    - webserver
  1. Create the webserver state tree:


apache:               # ID declaration
  pkg:                # state declaration
    - installed       # function declaration

The only thing left is to provision our minion using the highstate command. To initiate a highstate run, use the salt-call command:

salt-call --local state.highstate -l debug

The --local flag tells the salt-minion to look for the state tree in the local file system and not to contact a Salt Master for instructions.

To provide verbose output, used -l debug.

The minion first examines the top.sls file and determines that it is a part of the group matched by * glob and that the webserver SLS should be applied.

It then examines the webserver.sls file and finds the apache state, which installs the Apache package.
