Salt

`Salt <http://saltstack.org/>`_ is an open source infrastructure management tool.

It supports remote command execution from a central point (master host) to multiple

hosts (minions). It also supports system states which can be used to configure

multiple servers using simple template files.

Salt supports python versions 2.6 and 2.7 and can be installed via pip:

.. code-block:: bash

After configuring a master server and any number of minion hosts, we can run arbitrary

shell commands or use pre-built modules of complex commands on our minions.

The following command lists all available minion hosts, using the ping module.

.. code-block:: bash

The host filtering is acomplished by matching the minion id, or using the grains system.

The `grains <http://docs.saltstack.org/en/latest/topics/targeting/grains.html>`_ system

uses static host information like the operating system version or the CPU architecture to

provide a host taxonomy for the salt modules.

The following command lists all available minions running CentOS using the grains system:

.. code-block:: bash

Salt also provides a state system. States can be used to configure the minion hosts.

For example, when a minion host is ordered to read the following state file, will install

and start the Apache server:

.. code-block:: yaml

State files can be written using YAML, the Jinja2 template system or pure python.
