Configure Custom Salt Grains and Node Groups
When Salt manages large swathes of infrastructure, we need to be able to target exactly which servers we want to communicate with. This can be done via grains, which contain information about our underlying system — but we can also add grains information ourselves. We can additionally configure custom node groups using existing targeting methods to quickly reference common groups of nodes.
