I have a hiera configuration that specifies the following hierarchy:
:hierarchy:
- "nodes/%{::fqdn}"
- common
In this example, let''s say I''m using the puppetlabs ntp
module, which has a
parameter called "servers". I have a list of NTP servers that I want
to be
used by all but one node. On one of my nodes (let''s call that node
"agent1"), I want to use the default value for that servers parameter.
If I specify that list of servers in common.yaml, it will be applied to all
of the hosts (including on agent1). Is there something that I can put in
nodes/agent1.yaml that will force it to use the default parameter value,
while the other hosts use the servers that I specify in common.yaml? Is
there a way to tell hiera "stop looking for this value", and prevent
it
from continuing through the hierarchy? Even better would be a way to tell
it "stop looking for any value under ntp".
Thanks,
Marc

Sounds to me that your hierarchy needs some rethinking. "What makes this node special?" "Is it common to other nodes now or in the future?" "Does an existing fact exist that can be used in the Hiera hierarchy?" If the serverlist is moved from common.yaml up the hierarchy, you''d be able to solve your issue. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

If you have an exceptional node, then the Hiera approach is to provide that node''s exceptional data in a per-node hierarchy level. I fail to see why it would be better to embed an "abort lookup" marker in place of the data than it would be to put the actual desired data in that same place. Alternatively, if you don''t want to provide any data at all for a given (node, tag) pair, then structure your hierarchy and data so that no data file that applies to the node in question associates any value with the given tag.
