help to get this work on a sles12

[kundeng]

Hi, I followed the steps but couldn't get it to work:

This is what I am getting:
kundeng@splunkapp-preprod02:/opt/splunk/dnsdock> dig *.docker
;; Warning: Message parser reports malformed message packet.

; <<>> DiG 9.9.9-P1 <<>> *.docker
;; global options: +cmd
;; Got answer:

;; WHEN: Tue Apr 03 15:43:00 EDT 2018
;; MSG SIZE rcvd: 338

Why does the message parser complain that message is malformed??

Further I can ping dnsdock.docker but no other containers.
kundeng@splunkapp-preprod02:/opt/splunk/dnsdock> ping dnsdock.docker

I also ran this command for debug:
dig +norec @dnsdock.docker mule-ce.docker a
