Hi, I am having some DNS issues in my origin 3.7 cluster
I am seeing occasional dns lookup delays of around 1 to 5 seconds every 5 - 10 minutes In trying to find the cause I found in the origin-node logs the following about every second Jan 31 13:10:18 node01-2018.drivenow.com.au origin-node[39574]: I0131 13:10:18.042221 39574 logs.go:41] skydns: failure to forward request "read udp 10.118.56.32:53613->10.118.56.32:53: i/o timeout" However I can successfully do dns resolution on the node as per dig google.com @10.118.56.32 +short +search 216.58.200.110 And resolve internal IPs too dig docker-registry.default.svc @10.118.56.32 +short +search 172.30.99.40 Am I correct in my testing that origin-node is accessing the dnsmasq server on 10.118.56.32 ? I get the same issue on all three nodes. I can successfully run "oc adm diagnostics NetworkCheck" without any errors Any thoughts on where else to look ? Cameron
