Salt

Name: Salt
Availability: InStock

Salt talks to minions over a message bus: remote execution for one-shot commands, states (SLS) for desired config, pillar for secrets, grains for facts. This course covers targeting, the highstate, Jinja in states, the reactor, salt-ssh, and locking down the master. The master is a control plane; a reactor that fires on every event can change the fleet as fast as the bus can deliver.
