Re: [Puppet Users] How to inherit a parameterized class ? What is the syntax ?
Hi,
The 3rd option is interesting, i should try it to see.
So far i had tried a similar way, with a "realize", but instead of
overriding the content file, i had some conditional blocks with a variable
in the puppet.conf.erb file. And it did not work, because it seems the
variable was never known at the time of the first "realize" call (by the
class puppet). But with a content overide, it should work, i suppose

Re: [Puppet Users] How to inherit a parameterized class ? What is the syntax ?
Don't know if I am out on a limb here, but did you try setting class
defaults?
class puppet::master inherits puppet {
class { 'puppet': puppetmaster_fqdn => "my wanted value" }
# ...
}

My problem is that my class 'puppet' is a parameterized class:

and so, i don't find any syntax to inherit from it:

$with_cloud_provisioner = 'no'
) inherits puppet {

fails with
err: Could not retrieve catalog from remote server: Error 400 on
SERVER: Must pass puppetmaster_fqdn to Class[Puppet] at /etc/puppet/
modules/puppet/manifests/puppet.pp:1 on node (...)
I tried different ways to declare my class 'puppet::master', but i do
not find the right syntax, it always fails
class puppet::master ( $puppetmaster_fqdn = 'something',
$with_dashboard = 'yes',
$with_cloud_provisioner = 'no'
) inherits puppet {
# (...)
}
class puppet::master ( $with_dashboard = 'yes',
$with_cloud_provisioner = 'no'
) inherits puppet( puppetmaster_fqdn =>
'something' ) {
# (...)
}
What is the good syntax for that ?
Note also that i tried to work around the problem by using a virtual
resource for my File['/etc/puppet.conf'], and realize it in both
classes (without inheritance) but it did not end up as i wished. It
worked, but the templated file missed the content which should have
been triggered by the variables $with_dashboard from class
'puppet::master'

There's probably three ways to tackle it:
1. have the puppet class write a file called puppet.conf.agent, and
the master class write puppet.conf.master and cat puppet.conf.* >
puppet.conf.
2. use a variable and add some logic to the ERB template.
3. use the following syntax (be aware it realize and override):
In class puppet::master:
File <| title=='/etc/puppet/puppet.conf' |> {
content => template('puppet/puppetmaster.conf.erb'),
}
