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

Whichever you prefer. HTH, Felix -- You received this message because you are subscribed to the Google Groups "Puppet Users" group. To post to this group, send email to puppet-users@googlegroups.com.

Hi Felix, thanks for that hint. I missed the obvious ;-) (and learned a lot about the difference between classes and defines) Regards, Jens On 08.04.2011, at 09:04, Felix Frank wrote:>> How am i able to bring this together with parameterized classes?
