what is wrong with my config,the kubernetes dashboard config is in 8443 port? and in the same namespace,why it give port not found exception?
The port 8443 is container port,could not access outside the container.You should using this command to find the cluster service port:
kubectl get svc --namespace=kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kube-dns ClusterIP 10.254.0.2 <none> 53/UDP,53/TCP,9153/TCP 131d
kubernetes-dashboard NodePort 10.254.75.193 <none> 443:31085/TCP 131d
traefik ClusterIP 10.254.169.66 <none> 80/TCP,443/TCP,8080/TCP 2d4hthe port 443 is the cluster port treafik could access. change container port 8443 to port 443.
