DNS doesn't work on fresh installation
See original GitHub issueDNS doesn’t seem to work on a fresh installation of latest microk8s snap on Ubuntu 18.04. Inspecting the DNS pod with microk8s.kubectl describe pod -n kube-system kube-dns-6ccd496668-w84hj, I see:
Normal Scheduled 14m default-scheduler Successfully assigned kube-system/kube-dns-6ccd496668-w84hj to mike-ubuntu
...
Normal Created 10m kubelet, mike-ubuntu Created container
Normal Started 10m kubelet, mike-ubuntu Started container
Warning Unhealthy 10m kubelet, mike-ubuntu Liveness probe failed: HTTP probe failed with statuscode: 503
Running the kubernetes-suggested DNS busybox test microk8s.kubectl exec -ti busybox -- nslookup kubernetes.default, I get:
Server: 10.152.183.10
Address 1: 10.152.183.10 kube-dns.kube-system.svc.cluster.local
nslookup: can't resolve 'kubernetes.default'
command terminated with exit code 1
Any ideas what’s going on?
