What exact error do you have?
Are every Masters up and reachable?
oc get nodes
oc get ep kubernetes
Is on every machine the network manger setuped?
systemctl status NetworkManager
egrep ^ /etc/resolv.conf
egrep NetworkManager /etc/resolv.conf
Is on every machine the dnsmasq setuped?
systemctl status dnsmasq
egrep ^ /etc/dnsmasq.d/*

| Hi everyone, In OCP 3.5, we can query our services like below in dev environment where there is single node. Also org.xbill lib works. [root@ip-10-20-4-38 ec2-user]# nslookup hz.default.svc.cluster.local 172.30.0.1 Server: 172.30.0.1 Address: 172.30.0.1#53 Name: hz.default.svc.cluster.local Address: 10.129.0.130 Name: hz.default.svc.cluster.local Address: 10.129.0.131 But, on staging we have a multi-machine installation and we got DNS failures when we query with org.xbill.DNS.Lookup As a workaround, when we define DNS statically, which is 172.30.0.1, and pass to application it works, how can we overcome this static definition? Thanks in advance. |
