ERROR: logging before flag.Parse: W0802 17:26 1 server.go:64 Error getting metrics from dnsmasq: read udp 127.0.0.1:59054-127.0.0.1:53: read: connection refused This means that the health container is getting no response from dnsmasq container - which is all via local addresses in the same pod - so shouldn't be a k8s level networking issue. It implies something broken with the dnsmasq container. Edit: Actually - looking at the time stamps on the logs, its not clear, all the connection refusal messages were before dnsmasq was listening. So those messages are expected. Presumably they stopped after 17:53:35? Ok - version 1.28.4 solves it, works like a charm, thank you, I think we can close this issue.` $ kubectl -n default exec -ti busybox - nslookup kubernetes.default Server: 10.96.0.10 Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local Name: kubernetes.default Address 1: 10.96.0.1 kubernetes.default.svc.cluster.local Btw. Do you know why it can't resolve svc.cluster.local?

Kubernetes Kubectl Can't Find Server Ip

#deployment status metrics-server Back-off restarting failed container #container metrics-server-f5bc46bd7-hx8dc Back-off restarting failed container Maybe it can’t find the api-server addr，or the authorization is forbidden? The kube-apiserve is running on 6443 port. Are there have any docs i can read? It seems because deploy/1.8+/metrics-server-deployment.yaml doesn't have any options.

ADDITION: this problem happens after the commit., would you check this problem?

At the beginning, my problem is the same as yours. According to your method, I have made such an error.
