The External Nodes Classifier is a master tops subsystem that retrieves mapping information from major configuration management systems. One of the most common external nodes classifiers system is provided by Cobbler and is called
The cobbler-ext-nodes command can be used with this configuration:
master_tops: ext_nodes: cobbler-ext-nodes
It is noteworthy that the Salt system does not directly ingest the data sent from the
cobbler-ext-nodes command, but converts the data into information that is used by a Salt top file.
Any command can replace the call to 'cobbler-ext-nodes' above, but currently the data must be formatted in the same way that the standard 'cobbler-ext-nodes' does.
See (admittedly degenerate and probably not complete) example:
classes: - basepackages - database
The above essentially is the same as a top.sls containing the following:
base: '*': - basepackages - database base: '*': - basepackages - database
