Running puppet 3.7.4
I am new to puppet, and learning the syntax. For learning, I open up two
terminals, where I "vi foo.pp" in one terminal, and I "puppet apply foo.pp" on
the other terminal.
Using this:
node default {
notify{"syntax1":
message => $facts['osfamily']
}
}
I got this result:
Error: facts is not a hash or array when accessing it with osfamily at
/root/foo.pp:3 on node...
So then, using this:
node default {
notify{"syntax1":
message => $facts
}
}
I get this result:
Notice: /Stage[main]/Main/Node[default]/Notify[syntax1]/message: defined
'message' as 'syntax1'
Question 1: Why can't I access $facts?
So I wondered if maybe facts weren't available because I'm running "puppet
apply" instead of "puppet agent -t" but when I look here:
https://docs.puppet.com/puppet/3.7/reference/lang_facts_and_builtin_vars.html
They say "Before requesting a catalog (or compiling one with puppet apply),
Puppet will collect system information with Facter. Puppet receives this
information as facts..."
So I would expect $facts to be available.
Using this:
node default {
notify{"syntax1":
message => $os
}
}
I get this result:
Notice: /Stage[main]/Main/Node[default]/Notify[syntax1]/message: defined
'message' as '{"name"=>"RedHat", "family"=>"RedHat", "release"=>{"major"=>"7",
"minor"=>"2", "full"=>"7.2"}}'
So it seems, yes, at least *some* facts are available.
Using this:
node default {
notify{"syntax1":
message => $os['name']
}
}
I get this:
Error: os is not a hash or array when accessing it with name at /root/foo.pp:3
on node ...
Question #2: What's wrong with my syntax to access the OS name? I would expect
to be able to access $os['release']['major'] to get the result "7"
