is there a way to compare one facts with all other facts in the list

[Spriya]

Hi,

I have a requirement that,

I have list of two different facts

java_foundversion1_path1
java_foundversion2_path2
java_foundversion3_path3
java_foundversion4_path4

and java_authorizedversion1path1
java_authorizedversion2path2
java_authorizedversion3path3
java_authorizedversion4path4

and i am trying to compare each facts with all facts i.e java_found_version1path1 to all the list of java_authorized*. And if it founds any facts equal to java_found1version1path. It should notify us.

Is anything we can do it in puppet manifests?

If you are on puppet 3.7 you can easily iterate over facts. If you are
using future parser this can be done in
the puppet language, otherwise in Ruby (as a function or in a template).

You need to read
https://docs.puppetlabs.com/puppet/latest/reference/lang_facts_and_builtin_vars.html
to
understand which flags (if any) you need to change to get all the facts
into the variable $facts.
(The setting 'trusted_node_data = true' turns on the support I am using
in the example below).

If you are on a version before 3.7, it is much more difficult to do this
inside a manifest as it is difficult to
know which global variables are facts and which are not. You would
instead need to lookup the facts for a node
and act on that output directly with your own code).

With future parser you could do something like this:

$facts.each |$key, $val | {
if $key == 'the value you are looking for' {
# fail or notify or something
}
}

Hope that helps as a starting point.
