Use `Varstack <https://github.com/conversis/varstack>`_ to provide tops data
.. |varstack| replace:: **varstack**
This :ref:`master_tops <master-tops-system>` plugin provides access to
the |varstack| hierarchical yaml files, so you can user |varstack| as a full
:mod:`external node classifier <salt.tops.ext_nodes>` and
store state information (top data) in it.
Configuring Varstack
====================
To use varstack as a master top external node classifier, install varstack
as documented. Then, add to your master's configuration:
.. code-block:: yaml
master_tops:
varstack: /path/to/the/config/file/varstack.yaml
Varstack will then use /path/to/the/config/file/varstack.yaml (usually
/etc/varstack.yaml) to determine which configuration
data to return as adapter information. From there you can take a look at the
`README <https://github.com/conversis/varstack/blob/master/README.md>`_ of
varstack to learn how this file is evaluated. The ENC part will just return
the 'states' dictionary for the node.
Ie, if my.fqdn.yaml file contains:
.. code-block:: yaml
---
states:
- sudo
- openssh
- apache
- salt.minion
these will be returned as {'base': ['sudo', 'openssh', 'apache', 'salt.minion']} and
managed by salt as if given from a top.sls file.
