I''m in the process of trying to convert our current node
implementation to external nodes. The definitions that we called from
our node manifests have been replaced by variables passed back to
classes in modules. When using definitions, we could set default
values in the definition, and therefore we didn''t always have to pass
every argument. However, now that I am using variables to set data,
and calling definitions from that inside the classes, I have no way
that I can see to set default values.
Eg:
If the external node has:
---
classes:
- server_role::appServer
- elements::tfel4
environment: production
parameters:
tfel4_ClusterDescription: "Cluster1"
tfel4_ClusterWebUrl: "https://qa4.xxx.com"
tfel4_ClusterDbHost: "ora02.xxx.twofish.com"
tfel4_ClusterDbPort: 1521
tfel4_ClusterDbType: oracle
I would like the option to not to have to set tfel4_ClusterDbType, and
have it default to Oracle. In the class I have this:
some_definition {
key1 => val1,
dbprov => ${tfel4_ClusterDbType}
}
As you can see, since classes have no default values, I have to set it
some way. I tried this:
if ! defined($tfel4_ClusterDbType) {
$tfel4_ClusterDbType = "oracle"
}
but then returns an error:
"Could not retrieve catalog: interning empty string at
/etc/puppet/modules/elements/manifests/tfel4.pp:48"
I also tried:
case $tfel4_ClusterDbType {
"": { $tfel4_ClusterDbType = "oracle" }
}
which gives me this, indicating that the value wasn''t set.
"Could not retrieve catalog: Could not find template
/etc/puppet/modules/starterkit/templates/jboss_inst/deploy/eazyedb-xa-ds.xml..erb"
How can I do this?
Doug.

Even this doesn''t work: case $tfel4_ClusterDbType { undef: { $tfel4_ClusterDbType = "oracle" } } The use of undef is based on the puppet docs at http://docs.reductivelabs.com/guides/more_language.html. It just reports later that the variable tfel4_ClusterDbType has not been set. Doug. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
