Don't know salt ?
- Python based configuration management and orchestration engine
- Yaml syntax for salt formulas (puppet = modules)
-
Python modules to extend salt as you see fit
(puppet = types & providers)
- Very very fast
-
Uses zeromq by default, recently added RAET
(Reliable Asynchronous Event Transport)
Dashboard ?
Yeah... nope.
Or so YOU thought!
But what about Halite?
Not really what I was after
Returners to the rescue
- control where you want job reports sent to
- many returners already present
- redis, mongo, memcache, syslog, etc. Full list: salt.readthedocs.org
- 2014.7.0rc1 (Helium) comes with a elasticsearch returner
Using elasticsearch returner
- setup your minions and master to know to send data to ES
- /etc/salt/{master|minion}
elasticsearch: host: '192.168.122.1:9200' index: 'salt' number_of_shards: 1 number_of_replicas: 0 # # set returner to elasticsearch ext_job_cache: elasticsearch #
- restart masters and minions
- make sure that ES is accessible by all minions and masters (or proxy their connections)
