Actual results:
TASK: [openshift_node_dnsmasq | Test dns resolution] ************************** 
failed: [openshift-1.lab.eng.nay.redhat.com] => {"changed": false, "cmd": ["getent", "hosts", "google.com"], "delta": "0:00:00.004486", "end": "2016-04-07 23:35:51.601745", "rc": 2, "start": "2016-04-07 23:35:51.597259", "warnings": []}

check by manual, the dns works fine.
It is better to try to test dns for several times

Expected results:
This step should succeed

I've pushed a change that retries every second for up to 20 seconds. Please pull the latest and test.
Comment 2 Ma xiaoqiang 2016-04-11 01:01:28 UTC 
Install env successfully, move this issue to VERIFIED.
Comment 3 Ma xiaoqiang 2016-04-11 02:28:10 UTC 
The conditions for the dns port in the iptables didn't take effect.

Install ose-3.2 by default, check the iptables on the master
<--snip-->
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            state NEW tcp dpt:8053
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            state NEW udp dpt:8053
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            state NEW tcp dpt:53

<--snip-->

the '53' and '8053' port are opened.
