Re: [Puppet Users] Struggling with hiera 5 and puppet 4.10

[Sean]

Ok, I think I discovered the issues.

1.  for the r10k control repo, I cloned puppetlabs example, which has a 
directory called hieradata, but not hiera.yaml starter file.  So I think 
when I copied from the example of a hiera 5 config file, it uses the 
default data dir as "data", I needed this to be "hieradata".

2.  for my demo module, it appears I wasn't handling params correctly, and 
it seems that I can't fully qualify parameters in my code.  using 
$::demo::webhost produced an undefined variable warning.

Fixing these two things up and now I have working data.

Re: [Puppet Users] Struggling with hiera 5 and puppet 4.10

[Sean]

Thanks for that, I have read that blog plus the more recent followup.  I 
also have tried using the --explain flag for the lookup function.

Again if I run puppet lookup --node test.demo.local --explain demo::webhost 
on the puppet master, it produces a value for demo::webhost.  If I run on 
the agent node, it complains that hiera.yaml is using version 3 and that's 
deprecated, then produces no resulting value.

When puppet runs on the demo webserver with the class (that uses the 
demo::webhost value to configure an apache vhost resource), the 
demo::webhost value appears to be empty.  It produces a apache vhost config 
file in /etc/httpd/conf.d which has no hostname, no vhost name, no server 
name.  Everywhere in the resource where demo::webhost is used, there is no 
value in the resulting apache config file.

So perhaps the problem is in configuring hiera on the agents?  I guess I 
need to deploy the puppet/hiera module and try to ensure that all the 
agents are configured to use Hiera 5?  I haven't read anywhere that I need 
to deploy hiera.yaml files to agents, is that what I'm missing?

debuggin hiera problems.

Hi,

I'm working to prototype an upgrade of our environment to puppet 4.10
and use hiera 5 data layers.  Today, we're running puppet 3, and I've
refactored a our main modules to use hiera module data instead of
params.pp.  It better suits our needs to have the data layers setup this
way.  This prototype is also leveraging r10k, so the environment data is
stored in a control repo branch for each puppet environment.

Anyway, I'm struggling because the when I run puppet lookup on the
puppet master, I get a value for a parameter that hiera should be
serving data.  In the module data layer, the parameter defaults to
facts.hostname.  When I run puppet agent or puppet lookup on a node that
this module is applied to, I get nothing...e.g. if I use that piece of
data in an apache::vhost define, the config file in /etc/httpd/conf.d/
is 25-.mydomain.com.conf where it should be 25-www.mydomain.com.conf
because www is the value parameter hiera is looking up.  The same result
holds true even when I override the default value with something
specific at the environment layer, the lookup on the puppet master
produces the right value but the lookup on the agent returns nothing.

I'm something at a loss of what could cause this with out any errors or
useful information produced.  Might anyone have an idea where I've gone
wrong?

Thanks!

[Puppet Users] Struggling with hiera 5 and puppet 4.10

[Sean]

Hi,

I'm working to prototype an upgrade of our environment to puppet 4.10 and 
use hiera 5 data layers.  Today, we're running puppet 3, and I've 
refactored a our main modules to use hiera module data instead of 
params.pp.  It better suits our needs to have the data layers setup this 
way.  This prototype is also leveraging r10k, so the environment data is 
stored in a control repo branch for each puppet environment.

Anyway, I'm struggling because the when I run puppet lookup on the puppet 
master, I get a value for a parameter that hiera should be serving data. 
 In the module data layer, the parameter defaults to facts.hostname.  When 
I run puppet agent or puppet lookup on a node that this module is applied 
to, I get nothing...e.g. if I use that piece of data in an apache::vhost 
define, the config file in /etc/httpd/conf.d/ is 25-.mydomain.com.conf 
where it should be 25-www.mydomain.com.conf because www is the value 
parameter hiera is looking up.  The same result holds true even when I 
override the default value with something specific at the environment 
layer, the lookup on the puppet master produces the right value but the 
lookup on the agent returns nothing.

I'm something at a loss of what could cause this with out any errors or 
useful information produced.  Might anyone have an idea where I've gone 
wrong?

Thanks!
