[Puppet Users] Error 400 on SERVER: Cannot append, variable node_data is defined in this scope at
Hi,
I have an problem that I can''t get resolved. I have an hash like
www.krzywanski.net/archives/703.
With this hash i whould like the add some extra hashes before passing to
the module, i have tryed the code below.
node testnode {
class { ''testclass'':
nodes_data => {
''node1'' => { ''server'' =>
''node1.some.domain.com'', ''port'' =>
''2560'' },
''node2'' => { ''server'' =>
''node2.another.domain.com'', ''port''
=> ''2564'' },
''node3'' => { ''server'' =>
''node3.some.domain.com'', ''port'' =>
''2564'' }
}
}
}
class testclass ( $node_data ) {
node_data += {
''node4'' => { ''server'' =>
''node4.another.domain.com'', ''port'' =>
''2564'' },
''node5'' => { ''server'' =>
''node5.some.domain.com'', ''port'' =>
''2564'' }
}
class { ''moduletest::test'':
module_variable => $node_data
}
}
But then I get the error:
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Cannot append, variable node_data is defined in this scope at
/opt/puppet/env/manifests/classes/testclass.pp:1 on node
testmp-test-04.intern
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
Without adding the information everything works fine.
Kind regards,
Michiel Piscaer

Where you call the class you mention nodes_data, and inside the class it''s node_data. Unless this is not a one-to-one copy-paste that might be your problem? On Wed, Feb 22, 2012 at 15:21, M.

Re: [Puppet Users] Error 400 on SERVER: Cannot append, variable node_data is defined in this scope at
Thanks for the response, I see that I made an typo..
The parameter nodes_data needs to be node_data as I have corrected
below. But the error stands.
-------------- testnode.pp --------------
node testnode {
class { ''testclass'':
node_data => {
''node1'' => { ''server'' =>
''node1.some.domain.com'', ''port''
=> ''2560'' },
''node2'' => { ''server'' =>
''node2.another.domain.com'',
''port'' => ''2564'' },
''node3'' => { ''server'' =>
''node3.some.domain.com'', ''port''
=> ''2564'' }
}
}
}
-------------- testclass.pp --------------
class testclass ( $node_data ) {
node_data += {
''node4'' => { ''server'' =>
''node4.another.domain.com'', ''port''
=> ''2564'' },
''node5'' => { ''server'' =>
''node5.some.domain.com'', ''port'' =>
''2564'' }
}
class { ''moduletest::test'':
module_variable => $node_data
}
}
------------------------------------------
When delete the rows:
node_data += {
''node4'' => { ''server'' =>
''node4.another.domain.com'', ''port''
=> ''2564'' },
''node5'' => { ''server'' =>
''node5.some.domain.com'', ''port'' =>
''2564'' }
}
everything works fine. But then I still have the problem how to make the
settings that needs to be global and node specific at one hash?

There are a couple of limited ways in which you can make it *appear* to do so, but those are an illusions. In your case, the $node_data variable is a parameter to the class so it''s value is set according to the class''s declaration. You cannot thereafter change it, but you could create a new variable that contains the contents of node_data plus the additional data. I think it''s tricky to do that with a hash, though -- you might need to create a custom function. A technically superior solution, however, would be to use hiera for this problem. Aside from the fact that hiera is an all-around better solution for class data than is the current implementation of class parameters, hiera also has particular support for combining data from multiple levels of your data hierarchy. That appears to be exactly what you''re looking for. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
