ansible check DNS against FQDN

[John.1209]

I'm trying to come up with an ansible process to compare a DNS against an FQDN:

This is what I have:

---

 - name: Set DNS variable

   shell: dig {{ ansible_fqdn }} +short

   register: DNSOUT

   tasks:

     - name: Verify DNS

#     - command: /usr/bin/echo {{ ansible_fqdn }} not in DNS!

       command: /usr/bin/echo not in DNS!

       when: $ansible_fqdn != DNSOUT

This is not working?  Is there a better way to do this?  Or please suggest a fix.

Consider using the dig-lookup: https://docs.ansible.com/ansible/playbooks_lookups.html#the-dns-lookup-dig 

Cheers,

Your tasks: is misplaced and indentation is wrong, but this should work

- name: Set DNS variable

command: dig {{ ansible_fqdn }} +short
register: DNSOUT

- name: Verify DNS
command: echo not in DNS!
when: DNSOUT.stdout == ""

The Verify DNS task won't show you anything on in the console, if that's
what you are after you can do it like this

- debug: msg="{{ ansible_fqdn }} not in DNS!"
when: DNSOUT.stdout == ""
