After following @alexD 's advice I have added task to install facter, but I am still getting the same error:

- name: Install facter
  raw: apt install -y facter
  become: true
  tags: [docker]

- name: Check facter
  command: "facter ipaddress_eth1"
  register: result
  tags: [docker]

I am trying to understand what the difference is between the following:

$major_release = $::facts['os']['release']['major']
$selinux_is_enabled = $::facts['os']['selinux']['enabled']

If I put in my manifest:

notify { "major release is: ${major_release}": }

And then run this on my client side, it returns a value as expected. If I do the same for the selinux_is_enabled variable, it does not return a value, even though a

facter os.selinux.enabled

on the client side returns a "false".

Can anyone explain why the notify does not return an expected value for selinux enabled but it does for os release major?

I know that the following custom fact matches the string I want, as if I add a 'puts' or 'print' ahead of the $1 it prints the correct string. But as show the fact returns nothing. A blank.

  Facter.add(:myhost) do
    confine :kernel => "Linux"
    setcode do
      fh = File.open('/etc/enc_params.conf')
      fh.each_line do |line|
        if line =~ /\Amyhost.*\s(\w+)\Z/
          $1
        end
      end
    end
  end

I changed the domain name for some servers, i.e. web1.foo.com to web1.baz.com. In my Puppet Dashboard, I see two entries now for the same server.

I can destroy a node with something like rake node:fast_del name=web1.foo.com which seems to work (the web interface destroy doesn't work, see http://projects.puppetlabs.com/issues/6828) but only temporarily, eventually the old domain comes back. I checked facter on the host and I don't see any sign of the old domain in there, any idea why the old domain comes back?

I'm running ec2 debian instance and trying to get puppet working on it. I'd like my hostnames to be something more readable, so I've changed /etc/hostname, run /etc/init.d/hostname.sh start and I can see my human-readable hostname in the prompt. Every other app seems to be working fine with it, but not puppet (and actually it seems it's facter problem):

$ cat /etc/hostname 
service.XXX.com
$ hostname
service.XXX.com
$ facter | egrep '(host|domain)'
domain => compute-1.amazonaws.com
hostname => ec2-107-22-XXX-XXX
$ cat /etc/debian_version 
6.0.1

I've already cheched facter code and it seems it does not anything more than parsing hostname output. Where is this thing come from? I want my hostnames!
