Puppet Language Basics Feedback

I am taking this course as an "expert" for feedback purposes. I am being particularly nit-picky because that is what I would want if I asked for feedback :)

General Feedback

• Put the section "title" at the top. Maybe this would only help during the feedback phase, but I had to wait till I got to the next section to find out the title of the first one. (on the back button)
• If the test button is "disabled" there needs to be a reason
• There are several places where it is obvious that rspec is being used (from the errors), but upon success, I get the output passed which really doesn't need to be there. I recommend omitting the "passed" output if that is all there is, stick with the bold text "success" that is already there. In several cases, it might be better to have the puppet output, but in others it is probably not useful.
• The "errors" from the rspec-puppet tests made sense to me, but I think for a "Puppet 101" course, rspec-puppet is not going to be useful. The

Extract Puppet Environments and Roles for Morpheus

See inside for javascript to "translate" the output of Puppet API queries to name/value list for Morpheus.

Puppet Enterprise Setup

• Generate a certificate on the Puppet Master (CA) for morpheus
  • puppet cert generate morhpeus-api
• Grant Access to the environment_classes API
• Add mod 'puppetlabs-puppet_authorization', '0.5.0' to Puppetfile (if its not already there)

Setup Puppet Enterprise Code Manager to use Artifactory as Puppet Forge

Setup Artifactory

Actually installing Artifactory is outside the scope of this document. It is assumed that your have artifactory PRO or greater already running.

Here are the steps from their documentation on setting up the Puppet Repo: https://www.jfrog.com/confluence/display/RTF/Puppet+Repositories

In the additional files below, you will find a common.yaml and pe.conf fragment.

## site.pp ##

# This file (/etc/puppetlabs/puppet/manifests/site.pp) is the main entry point
# used when an agent connects to a master and asks for an updated configuration.
#
# Global objects like filebuckets and resource defaults should go in this file,
# as should the default node definition. (The default node can be omitted
# if you use the console and don't define any other nodes in site.pp. See
# http://docs.puppetlabs.com/guides/language_guide.html#nodes for more on
# node definitions.)
