You canĬlassify nodes with node definitions or by using node-specific data from outside your Set of classes to each node, based on the node's role in your infrastructure. Node classification allows you to assign a different To add a class's resources to the catalog, either declare the class inĪ manifest or classify your nodes. "database server" or "web application worker." In turn, small classes that manage a few resources canīe combined into larger classes that describe entire custom system roles, such as Whereas a resource declaration might manage the state ofĪ single file or package, a class declaration can manage everything needed to configureĪn entire service or application, including packages, configuration files, serviceĭaemons, and maintenance tasks. Just as you declare a single resource, you can declare a class to Other part of the Puppet language exists to addįlexibility and convenience to the way you declare resources. When you declare a resource, you tell Puppet the desired state for that resource, so that Puppet can add it to the catalog and manage it. You can group resources together in classes, which generallyĬonfigure larger chunks of functionality, such as all of the packages, configuration files,Īnd services needed to run an application.Īround resource declaration.
