Hi all,
i try to run a puppet-setup that is not based on hostnames, but facts i supply
to facter. The idea is described here
https://github.com/jordansissel/puppet-examples/blob/master/nodeless-puppet/README.rdoc,
but a basic example would be
----
if has_role("loadbalancer") {
include loadbalancer::service
} else {
# Otherwise, this machine is not a loadbalancer
include loadbalancer::remove
}
----
How am i able to bring this together with parameterized classes? For instance
this will complain about redefinition of class ''haproxy''.
---
class haproxy ($conf = "puppet:///modules/haproxy/proxy.conf") {
}
if has_role("loadbalancer") {
class { ''haproxy'': conf =>
"puppet://modules/haproxy/conf1" }
} else {
class { ''haproxy'': conf =>
"puppet://modules/haproxy/conf2" }
}
---
How can i "import" parameterized classes? Is there a work-around?
I am quiet new to puppet, so if i missed the obvious or google keywords, please
point me to the right direction.
Regards, Jens

Hi, I believe that you can only do this in the node definition - though the documentation doesn''t specifically say this.

Perhaps the client log showing the actual error message and its context would help, especially if debug-level logging were enabled. On the other hand, I''m not a big fan a parameterized classes. There are good use cases for them, but I think they are the wrong tool for most jobs. I would write your particular example without them, but also without class inheritence: class haproxy { if has_role("loadbalancer") { $conf = "puppet://modules/haproxy/conf1" } else { $conf = "puppet://modules/haproxy/conf2" } } # ... include ''haproxy'' ###### Many uses of parameterized classes can be rewritten in a similar way to use unparameterized ones, simply by pushing the parameter selection logic down into the class. That''s especially suitable where the parameter logic is based on relatively generic facts (e.g. roles), rather than on highly node-specific ones (such as hostnames).
