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.
