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 pillars
==============

Reclass storage with data fetched from git

.. code-block:: yaml

    reclass:
      storage:
        enabled: true
        base_dir: /srv/reclass
        data_source:
          engine: git
          address: git@repo.domain.com:reclass/reclass-project.git
          revision: master

Reclass storage with local data source

.. code-block:: yaml

    reclass:
      storage:
        enabled: true
        base_dir: /srv/reclass
        data_source:
          engine: local

Reclass model with single node definition

.. code-block:: yaml

    reclass:
      storage:
        enabled: true
        node:
          service_node01:
            name: svc01
            domain: deployment.local
            classes:
            - cluster.deployment_name.service.role
            params:
              salt_master_host: <<salt-master-ip>>
              linux_system_codename: trusty
              single_address: <<node-ip>>

Reclass model with multiple node defined

.. code-block:: yaml

    reclass:
      storage:
        enabled: true
        repeat_replace_symbol: '<<count>>'
        node:
          service_node01:
            name: node<<count>>
            domain: deployment.local
            classes:
            - cluster.deployment.service.role
            repeat:
              count: 2
              start: 5
              digits: 2
              params:
                single_address:
                  value: 10.0.0.<<count>>
                  start: 100
                deploy_address:
                  value: part-<<count>>-whole
                  start: 5
                  digits: 3
            params:
              salt_master_host: <<salt-master-ip>>
              linux_system_codename: trusty

Reclass storage with arbitrary class mappings

.. code-block:: yaml

    reclass:
      storage:
        enabled: true
        ...
        class_mappings:
        - target: '\*'
          class: default
