title: kubernetes coredns resolution is failing systematically
body: <p>DNS revolution is systematically failing in my 3 node cluster. I have reviewed the official debugging kubernetes documentation and did not find a resolution. My cluster nodes are CentOS 7 vm's and I'm using a Weave net CNI for Multicast support. Using sniff I was able to get a tcpdump of the DNS messages. What can I do to resolve the DNS failure?</p>
