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.
Successfully complete this lab by achieving the following learning objectives:
- Configure Custom Grains
Add custom grains files to each provided server, based on the information in the instructions.
- Configure Node Groups
Configure a node group for each feature grain referenced.
- Test Each Node Group
Ensure everything is working by running
test.pingagainst each node group.
