Puppet spends a lot of time making sure there aren’t any “question dumps” or ways to game the system out there to keep the certification valuable. If you follow the study guide and go to the certification lounge, register, and take all the sessions, you should be rather well prepared from a theory perspective. You should also have some knowledge of administering Puppet directly to have maximum success.

Is there an option to force the puppetserver to log all lookups and the manifest which includes the lookup?

@Allahshukur Ahmadzada I would also point you to our Puppet Practice Labs on the Puppet Education site: https://training.puppet.com/pages/20/puppet-practice-labs These labs provide an easy zero-install way to get hands-on with a variety of different Puppet-related topics. These are the same labs that we offer in our free PE 101, PE 201 and PE 301 classes that we also encourage you to take a look at: https://training.puppet.com/pages/23/instructor-led-training If you have any questions, just let me know!

if I run the following map

$query = $node_hostnames.map |$node| { "certname='${node}'" }

using this data:

mm::node_hostnames: 
  - 'hostname1.internal'
  - 'hostname2.internal'

will i get an array

$query == ["certname='hostname1.internal'",""certname='hostname2.internal'""]

the puppet lambdas still confuse me.

that looks like exactly what map should do

Yep, you'll get an array of strings

it takes the array you're mapping and returns an array of whatever the lambda returns

cool, thanks @Lumiere @Skylar Thompson

@Jason Grammenos I often use

puppet apply

for testing programming constructs with no resources involved, and I haven't used it as much, but I'll bet you can do the same in https://demo.puppet-debugger.com/. I create small .pp files like so:

$node_hostnames = [ 'hostname1.internal', 'hostname2.internal' ]
$query = $node_hostnames.map |$node| { "certname='${node}'" }

notice($query)

And then run

puppet apply /tmp/maptest.pp

to see output:

Notice: Scope(Class[main]): [certname='hostname1.internal', certname='hostname2.internal']
Notice: Compiled catalog for gregs-macbook-pro.local in environment production in 0.04 seconds
Notice: Applied catalog in 0.02 seconds

Hope that's helpful

@Moe epp is newer than erb; erb still works but not everyone will have migrated everything. epp templates are rendered with the

epp()

function not

template()

ie: template() is for erb not epp

@glee Aha! Thanks for the pointer! I just switched the file resource to

epp()

and got new error messages. I'll try to figure them out first and if I hit a wall I might return 🙂

I'd recommend to pass variables explicitly into the epp template (2nd arg of epp() function)

I have read that, but at first I want to get it to work at all and then optimize it.

@glee Thanks again! I found the remaining issues with my manifest and template code and iterating over a hash using epp works now. 🙂
