Salt
====

Salt is a new approach to infrastructure management. Easy enough to get running in minutes, scalable enough to manage tens of thousands of servers, and fast enough to communicate with them in seconds.

Salt delivers a dynamic communication bus for infrastructures that can be used for orchestration, remote execution, configuration management and much more.

Sample pillars
==============

Salt master
-----------

Salt master with base production environment and pillar tree as metadata backend

.. literalinclude:: tests/pillar/master_single_pillar.sls
   :language: yaml

Salt master with reclass ENC as metadata backend

.. literalinclude:: tests/pillar/master_single_reclass.sls
   :language: yaml

Salt master with API

.. code-block:: yaml

    salt:
      master:
        ...
      api:
        enabled: true
        port: 8000

Salt master with preset minions

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        minions:
        - name: 'node1.system.location.domain.com'

Salt master with alternative installation source and version (optional) - pip

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        source:
          engine: pip
          version: 2016.3.0rc2

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        environment:
          prd:
            keysone:
              source: pkg
              name: salt-formula-keystone

Clone master branch of keystone formula as local feature branch

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        environment:
          dev:
            formula:
              keystone:
                source: git
                address: git@github.com:openstack/salt-formula-keystone.git

Salt master syndicate master of masters

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        syndic:
          mode: master

Salt master syndicate (client) master

.. code-block:: yaml

    salt:
      master:
        enabled: true
        ...
        syndicate:
          mode: client
          host: master-master

Salt master with custom handlers

.. code-block:: yaml

    salt:
      master:
        enabled: true
        handler:
          handler01:
            engine: udp
            bind:
              host: 127.0.0.1
              port: 9999
      minion:
        handler:
          handler01:
            engine: udp
            bind:
              host: 127.0.0.1
              port: 9999
          handler02:
            engine: zmq
            bind:
              host: 127.0.0.1
              port: 9999
