Salt Syndic
|
|
===========
|
|
|
|
The Salt Syndic interface is a powerful tool which allows for the construction
|
|
of Salt command topologies. A basic Salt setup has a Salt Master commanding a
|
|
group of Salt Minions. The Syndic interface is a special passthrough
|
|
minion, it is run on a master and connects to another master, then the master
|
|
that the Syndic minion is listening to can control the minions attached to
|
|
the master running the syndic.
|
|
|
|
The intent for supporting many layouts is not presented with the intent of
|
|
supposing the use of any single topology, but to allow a more flexible method
|
|
of controlling many systems.
|
|
|
|
Configuring the Syndic
|
|
======================
|
|
|
|
Since the Syndic only needs to be attached to a higher level master the
|
|
configuration is very simple. On a master that is running a syndic to connect
|
|
to a higher level master the syndic_master option needs to be set in the
|
|
master config file. The syndic_master option contains the hostname or ip
|
|
address of the master server that can control the master that the syndic is
|
|
running on.
|
|
|
|
The master that the syndic connects to sees the syndic as an ordinary minion,
|
|
and treats it as such. the higher level master will need to accept the syndic's
|
|
minion key like any other minion. This master will also need to set the
|
|
order_masters value in the configuration to True. The order_masters option in
|
|
the config on the higher level master is very important, to control a syndic
|
|
extra information needs to be sent with the publications, the order_masters
|
|
option makes sure that the extra data is sent out.
|
|
|
|
Running the Syndic
|
|
==================
|
|
|
|
The Syndic is a separate daemon that needs to be started on the master that is
|
|
controlled by a higher master. Starting the Syndic daemon is the same as
|
|
starting the other Salt daemons.
