While developing Puppet Modules with class parameters, data from the
user should be validated as per the Style Guide. Puppet should fail
early and hard in the situation of invalid data being passed into the
module.
This function provides a more concise method to the alternative of using
if statements in the Puppet manifests.
Many modules I'm working on need a standard but
relatively granular location in the catalog. For example,
any module that configures the packaging system should
run "early"
Add the following stages which have inter-dependencies
in the top to bottom order listed:
* setup
* deploy
* runtime
* setup_infra
* deploy_infra
* main
* setup_app
* deploy_app
