Netplan (supplied with stock Ubuntu 18.04) changes some stuff around DNS config. Kubernetes by default uses /etc/resolv.conf for dns configuration. With Ubuntu 18.04 the info in /etc/resolv.conf is not correct. Pods running are unable to resolve external dns requests.
The kubespray var kube_resolv_conf should point to /run/systemd/resolve/resolv.conf.
There is a simulair bug report on this in kubespray but the solotion over there didn't work for me (#3035). There is also a report in the kubernetes/kubeadm repo on this: kubernetes/kubeadm#787
I also have a PR ready for a fix on this. This will be available shortly.
