I have a node definition that passes a parameter that sets a certain
version of code being installed on a node, like this...
elements::customer {
tfel0:
ensure => running,
enable => true,
version_core => "1.18.29-1",
...
}
Our developers decided that versions of code after 1.22 need a new
file deployed . I therefore need to do a numerical comparison on
$version_core and it''s greater than or equal to 1.22, push this file.
I can''t get it to work.
I can''t do a pure mathematical comparison because the "-" is
in the
version number. I tried splitting that into two and passing the
version as 1.18.29, but puppet complains about the ".".... you
can''t
pass a float to a definition?
This is version 0.24.8.... what options do I have?
Doug.

It didn''t quite work in puppet 0.24.8, but if you copy lib/puppet/parser/functions/versioncmp.rb from puppet-0.25.0 then it should work. See issue #2110. I think you want somethng like this: if (versioncmp($version, "1.22") >= 0) { # do stuff } --apb (Alan Barrett) -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
