Hi Ken,
I got it to work! Whew. But not by removing 'firewall'. I
actually need to include this class in my testing, because it gets
included by default on all nodes as part of my 'common::suse' class.
The problem was that puppet agent was not even using the correct
class list for some mysterious and buggy reason. My external_node
command returns the correct class list as you have above, but when I
looked carefully at the puppet output (sleep helped here) I saw that
the agent was not even hitting class 'firewall_wrapper' but a
different testing class called 'firewall_extras':
unxslet01:/var/lib/puppet # puppet agent -t
info: Retrieving plugin
info: Loading facts in adinfo
info: Loading facts in adinfo
info: Caching catalog for unxslet01.ucop.edu
info: Applying configuration version '1308273896'
notice: 22 9080 3000
notice: /Stage[main]/Firewall_extras/Notify[msg]/message: defined 'message' as

notice: 22
notice:
/Stage[main]/Firewall/Firewall::Firewall_conf[default]/Notify[msg1]/message:
defined 'message' as '22'
notice: Finished catalog run in 8.59 seconds
I could not figure out why. I tried removing the cached catalog and
restating puppet agent, but still the wrong class was used. Only
after I deleted the 'firewall_extras' class from my manifest entirly
did agent use the configured class:
unxslet01:/var/lib/puppet # puppet agent -t

I was not able to reproduce this bug.

Re: [Puppet Users] dashboard ENC and parameterized classes
So:
name: unxslet01.ucop.edu
parameters:
fw_tcp_ports: 22 9080 3000
classes:
- firewall_wrapper
- common::suse
- firewall
Is including both 'firewall' and 'firewall_wrapper'. But I think you
are hitting non-deterministic ordering here ... you only really want
to include 'firewall_wrapper' and have that pull in 'firewall'.
Otherwise, you may pull in 'firewall' too early, which would apply its
default settings.
So drop 'firewall' from your classes in dashboard and you may find it
does the correct thing ...
FYI, this works for me:
kbarber:tmp ken$ puppet --version
2.6.8
kbarber:tmp ken$ cat inherits.pp
class firewall {
define firewall_conf ($fw_services_ext_tcp = "22") {
notify { "msg1": message => $fw_services_ext_tcp, }
}
firewall_conf {"default": }
}
class firewall_override ( $tcp_ports ) inherits firewall {
Firewall::Firewall_conf["default"] {
fw_services_ext_tcp => $tcp_ports,
}
notify { "msg0": message => $tcp_ports, }
}
class firewall_wrapper {
class { "firewall_override": tcp_ports => $::fw_tcp_ports, }
}
$fw_tcp_ports = "22 100 2323"
include firewall_wrapper

I did not know about running the external_nodes on the command line. Thanks
for the tip.
With siplified version I am at least getting some error output. this is
progress:
class firewall_extras (
$services = undef
) {
notify { "msg": message => $services }
}
class firewall_wrapper {

Re: [Puppet Users] dashboard ENC and parameterized classes
Certainly works for me in a simplified example ... can you simplify
your example so it just does a notify?
class firewall_extras (
$services = undef,
) {
notify { "msg": message => $services }
}
class myfirewall {
class { "firewall_extras": services => $::firewall_services }
}
Also - just for kicks - what is the yaml output of your external_nodes
command when you run this on the command line?
(you probably already know how to do this but ...)
To figure out the path its just:
puppet master --configprint external_nodes
Then run it like:
/somepath/external_nodes unxslet01.ucop.edu

Re: [Puppet Users] dashboard ENC and parameterized classes
What errors are you getting when you use this pattern? Do you have
sample code and errors for your use case?
I presume you are doing an:
include foo::wrapper
At some point to evaluate that wrapper class? Otherwise nothing will happen.

[Puppet Users] dashboard ENC and parameterized classes
Looking at the release notes for dashboard 1.1.1, I see that param
classes are not yet supported within dashboard's external node
classifier feature. A few months ago I saw a post suggesting the
following work around until there is support:
class foo ($var="default") {
notify { $var: }
}
Parametrized classes are new in Puppet 2.6. Support for parametrized
classes via ENC was introduced in 2.6.5. Support for parametrized
classes in dashboard is on the road map.
Currently here's the way to declare parametrized classes in site.pp:
node node01 {
class { foo:
var => "hello world!",
}
}
To support parametrized class in dashboard, I write a wrapper class
(necessary until Dashboard fully supports parametrized classes):
class foo::wrapper {
class { foo:
var => $::foo_var,
}
}
In this case assign class foo::wrapper to node1 in dashboard and
configure the parameter foo_var="hello world!".

I am tring to replicate this workaround without success. Has anyone
else gotten param classes working within dashboard ENC?
