Hi all,
I have a custom facts script that is distributed to all of my puppet
clients. This first thing this script does is read a file on the client to
determine the ''type'' of server that it is. Later in the
script, I would
like to change the value based on some additional information. I don''t
seem
to be able to modify the value of a fact once it has been set. For example
Facter.add("server_type") do
setcode do
"apache_web_server"
end
end
# Later I may want to change the value.
if Facter.value("http_server") = "false"
# Change value of "server_type" here. I have tried many different
approaches but none work.
end
Any advice would be greatly appreciated.

Of course should be == and not
if Facter.value("http_server") == "false"
# Change value of "server_type" here. I have tried many different
approaches but none work.

It may be best to hold your value in a temporary variable and just have the setcode run at the end. I can''t remember where I read it, but I don''t think ruby custom facts can override other ruby custom facts once they are set (thought I believe the FACTER_ environment variables can override ruby custom facts).

Thanks ZJE. That is what I ended up doing.

You can have multiple resolutions for a single fact, and use fact precedence to determine which ones should be used first. http://docs.puppetlabs.com/guides/custom_facts.html#fact-precedence has the details on this.

I''m doing something similar in one environment… I''ve come to realize this method contains less awesome than I''d anticipated. What I''d suggest doing, is changing the file deployed to the client into a template that''s deployed via puppet.. have that template set the content correctly for the machine in question when it''s deployed. The HOW you go about doing that varies greatly depending on your environment… This way you''re not trying to override facts, which is generally an adventure in undergoodness. my $.02 On Jul 31, 2012, at 3:38 PM, rjl <rjlindal@gmail.com> wrote:> Hi all, > I have a custom facts script that is distributed to all of my puppet clients.
