I have created kops cluster and elasticsearch logging as below.
kops create cluster --zones ap-southeast-1a,ap-southeast-1b,ap-southeast-1c --topology private --networking calico --master-size t2.micro --master-count 3 --node-size t2.micro --node-count 2 --cloud-labels "Project=Kubernetes,Team=Devops" ${NAME} --ssh-public-key /root/.ssh/id_rsa.pub --yes
https://github.com/kubernetes/kops/blob/master/addons/logging-elasticsearch/v1.7.0.yaml
then some important cluster information.
root@ubuntu:~# kubectl get services -n kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
elasticsearch-logging ClusterIP 100.67.69.222 <none> 9200/TCP 2m
kibana-logging ClusterIP 100.67.182.172 <none> 5601/TCP 2m
kube-dns ClusterIP 100.64.0.10 <none> 53/UDP,53/TCP 6m
root@ubuntu:~# kubectl cluster-info
Kubernetes master is running at https://${NAME}
Elasticsearch is running at https://${NAME}/api/v1/namespaces/kube-system/services/elasticsearch-logging/proxy
Kibana is running at https://${NAME}/api/v1/namespaces/kube-system/services/kibana-logging/proxy
KubeDNS is running at https://${NAME}/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
now when i access "https://${NAME}/api/v1/namespaces/kube-system/services/kibana-logging"
i got as below in browser
