Minion Data Cache
2016.11.0
The Minion data cache contains the Salt Mine data, minion grains and
minion pillar information cached on the Salt Master. By default, Salt
uses the localfs cache module to save the data in a
msgpack file on the Salt Master.
Pluggable Data Cache
While the default Minion data cache is the localfs
cache, other external data stores can also be used to store this data
such as the consul module. To configure a Salt Master to
use a different data store, the cache setting needs to be established:
cache: consulThe pluggable data cache streamlines using various Salt topologies
such as a Multi-Master <tutorial-multi-master> or Salt Syndics <syndic>
configuration by allowing the data stored on the Salt Master about a
Salt Minion to be available to other Salt Syndics or Salt Masters that a
Salt Minion is connected to.
Additional minion data cache modules can be easily created by modeling the custom data store after one of the existing cache modules.
See cache modules <all-salt.cache> for a current
list.
Configuring the Minion Data Cache
The default localfs Minion data cache module doesn't
require any configuration. External data cache modules with external
data stores such as Consul require a configuration setting in the master
config.
Here's an example config for Consul:
consul.host: 127.0.0.1
consul.port: 8500
consul.token: None
consul.scheme: http
consul.consistency: default
consul.dc: dc1
consul.verify: True
cache: consul
