Reclass Formula
===============

reclass is an "external node classifier" (ENC) as can be used with automation
tools, such as Puppet, Salt, and Ansible. It is also a stand-alone tool for
merging data sources recursively.


Sample Metadata
===============

Install sources from [repository, git, pip]


.. code-block:: yaml

    salt:
      source:
        engine: pkg
    ...
      source:
        engine: git
        repo: git+https://github.com/salt-formulas/reclass
        branch: master
    ...
      source:
        engine: pip
    ...

If reclass is pre-installed, set the engine to None to avoid updates.

.. code-block:: yaml

    salt:
      source:
        engine: None


Reclass storage with data fetched from git

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

Reclass storage with local data source

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

Reclass storage with archive data source

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

Reclass storage with archive data source with content hash check

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

Reclass model with single node definition

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

Reclass model with multiple node defined

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

Reclass model with multiple node defined and interpolation enabled

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

Reclass storage with simple class mappings

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

Reclass models with dynamic node classification

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

Classify node after creation and unclassify on node deletion

.. code-block:: yaml

    salt:
      master:
        reactor:
          reclass/minion/classify:
          - salt://reclass/reactor/node_register.sls
          reclass/minion/declassify:
          - salt://reclass/reactor/node_unregister.sls

Event to trigger the node classification

.. code-block:: bash

    salt-call event.send 'reclass/minion/classify' "{'node_master_ip': '$config_host', 'node_ip': '${node_ip}', 'node_domain': '$node_domain', 'node_cluster': '$node_cluster', 'node_hostname': '$node_hostname', 'node_os': '$node_os'}"

.. note::

    You can send any parameters in the event payload, all will be checked
    against dynamic node classification conditions.

    Both actions will use the minion ID as the node_name to be updated.

Event to trigger the node declassification

.. code-block:: bash

    salt-call event.send 'reclass/minion/declassify'
