Puppet

Puppet is pull-based: the agent sends facts, the master compiles a catalog, the node converges. This course covers resources and the RAL, manifests, classes, Hiera and eyaml, roles and profiles, and PuppetDB. A signed cert is trust; whoever holds the master can change every node that checks in.
