Hi everyone, Do you guys know any article/doc talking about the use of roles/profiles approach with hiera? I''m particularly interested in how to organize the manifests when having multiple data centers, parametized classes and wants to use hiera. Being even more specific, how to organize the code using the Craig''s article (http://www.craigdunn.org/2012/05/239/) and use hiera to provide node specific data. thank you, -fred -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Excellent.. thanks!
And now sorry for the long email... hopefully I''m clear enough.
I''d also to expose one example that I have here in my company.
I''m not too
confident of how we setup roles and profiles, specially when it comes to
add hiera into the game.
Say we have a module called zabbix20::agent. The configuration file will be
generated using erb templated with data coming from parametized classes. So
far, it looks good. Data separation, modules look portable, etc.
As far as I understood going through the article is that you define the
technology stack in the profile, and the role as collection of profiles.
Well, in that case I''d say I would have something similar to this:
class profile::zabbix20::server {
class { ''::zabbix20::server'' :
bind_ip => "1.2.2.3",
...
}
}
and then it would probably go to a base profile (profile::base) and
inherited by a base role. That fits perfectly with single site scenario.
Say you now have multiple data centers with different zabbix servers on
each. The way I understood ...
class profile::zabbix20::server::dc1 {
class { ''::zabbix20::server'' :
bind_ip => "1.2.2.3",
...
}
}
class profile::zabbix20::server::dc2 {
class { ''::zabbix20::server'' :
bind_ip => "1.2.3.4",
...
}
include httpd
...
}
then the roles:
class role::zabbix20::server::dc1 {
include profile::zabbix20::server::dc1
}
and the nodes ...
node ''a.b.c.d'' { include include
profile::zabbix20::server::dc1 }
node ''x.y.z.w'' { include include
profile::zabbix20::server::dc2 }
That being said ... How would I actually add hiera into the game? I
don''t a
straightforward way to use hiera and benefit the data separation. I have to
include the business logic in the profile. How would I actually do that
using hiera? Can''t see a direct way.
The other discussion I had with my co-worker is ... they actually created
two modules: roles and profiles. If I want to change, I have to actually
change the modules. Isn''t it desirable to have these out of the
modulespath? I don''t see why we have to do this way if are trying to
abstract things and avoiding touching modules whenever we can.
Thanks in advance.

LIke this:
class profile::zabbix20::server (
bind_ip,
...
) {
class { ''::zabbix20::server'':
bind_ip => $bind_ip,
...
}
}
Then your hieradata would set
in a.b.c.d.yaml:
profile::zabbix20::server::bind_ip: 1.2.2.3
in x.y.z.w.yaml:
profile::zabbix20::server::bind_ip: 1.2.3.4
That way you have a single profile for all datacenters.

Thanks Chad ... I understand it from the syntax point of view, but my point is more of a conceptual question in how to apply Craig''s concepts using hiera with parasitized classes ... in that case, the node definition using hiera declares one (and only one role). The profile would define the technology stack with all the modules. That''s what Craig''s article suggests (he doesn''t mention hiera in the article). A role could specify 1+ profiles. So far, great. The thing is, in the node definition, using hiera, I''d break what they''re proposing, because I''m actually not totally separating and externalizing the data. The yaml file would be (the way I see). x.y.z.w.yaml: role::zabbix20::server::dc2 a.b.c.d.yaml: role::zabbix20::server::dc1 Now, what I expected to have, for example, is the bind_ip parameter passed here in hiera, not in the profile definition. I hope I''m being clear ... :-) -frederiko On Tue, Sep 3, 2013 at 2:19 PM, Chad Huneycutt <chad.huneycutt@gmail.com>wrote:> LIke this: > > class profile::zabbix20::server ( > bind_ip, > ... > ) { > class { ''::zabbix20::server'': > bind_ip => $bind_ip, > ... > } > } > > Then your hieradata would set > > in a.b.c.d.yaml: > profile::zabbix20::server::bind_ip: 1.2.2.3 > > in x.y.z.w.yaml: > profile::zabbix20::server::bind_ip: 1.2.3.4 > > That way you have a single profile for all datacenters. > > - Chad > > > On Tue, Sep 3, 2013 at 11:49 AM, Frederiko Costa <frederiko@gmail.com> > wrote: > > Excellent.. thanks! > > > > And now sorry for the long email... hopefully I''m clear enough. > > > > I''d also to expose one example that I have here in my company.

Without hiera you have all those extra classes you posted below
including this very specific one. I think your classes are too
complicated to begin with regardless of where the data is, but the lack
of data separation probably sent you down that path.
class role::zabbix20::server::dc1 {
include profile::zabbix20::server::dc1
}
With Hiera this is enough
include role::zabbix
You''re now thinking, "How do I specify this machine is a server,
in dc1,
and installing zabbix 2?" To answer we will start over and try to build
what you have with Hiera. This is a little hard to deal with in email,
but I think you''ll get the idea.
node zabbixserver {
# this is a top level role for the zabbix server
include role::zabbix
}
class role::zabbix {
include profile::base
include profile::zabbixserver
}
class profile::zabbixserver {
include profile::apache
include zabbix
}
class zabbix(
$bind_ip = 127.0.0.1,
$version = present,
) {
blah blah
}
This Hiera config assumes you have a dc and role fact of some sort. This
may or may not be easy in your environment.
hiera.yaml
---
:hierarchy:
- %{fqdn}
- %{dc}
- %{role}
- %{environment}
- common
This is our role data
./hieradata/common.yaml
---
zabbix::version: ''2.0''
zabbix::bind_ip: ''1.1.1.1''
These are the dc bits of data
./hieradata/dc1.yaml
---
zabbix::bind_ip: ''1.2.3.1''
./hieradata/dc1.yaml
---
zabbix::bind_ip: ''1.4.5.1''
Your parametrized class will autolookup matching parameters from Hiera
in Puppet 3.x or you can specify them manually. Machines in dc1 get
1.2.3.1, dc2 gets 1.4.5.1, and any machine gets 1.1.1.1.
In summary we move data into Hiera and replace module::someclass::dc
with a simple module that does a lookup to a data file based on facts
that have classified the node.

Hi, Ramin - you are correct. I got down to this path when I decided to follow this pattern. It turns out that it became overkill. In regards to hiera, that''s also exactly what I was looking at. I knew I''d be nuts if I had to differentiate for each DC. Not clever whatsoever. I thought about facts and I actually wrote one to tell which DC the host is at. That would make my life easier, I thought. All I need is to make sure hiera uses it. I will implement following you suggestion. That''s the path I was looking for. The only thing I might not need it is the role fact, but I wanted to get my hands dirty first and make sure I don''t need it. thanks! -fred -frederiko On Tue, Sep 3, 2013 at 4:07 PM, Ramin K <ramin-list@badapple.net> wrote:> Without hiera you have all those extra classes you posted below > including this very specific one.
