What happened:
Using kubeadm page I installed a three node cluster.

$ kc describe nodes | awk '/Addresses/ {print $2}' | awk -F',' '{print $3}' 
knode-0
knode-1
knode-master

Installed canal pod-network:

kubectl create -f https://raw.githubusercontent.com/tigera/canal/master/k8sinstall/kubeadm/canal.yaml

Nodes, services, pods were healthy at this time. So proceeded to dashboard

kubectl create -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml

$ kubectl get -n kube-system services
NAME                   CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
canal-etcd             10.96.232.136    <none>        6666/TCP        5m
kube-dns               10.96.0.10       <none>        53/UDP,53/TCP   13h
kubernetes-dashboard   10.110.163.186   <nodes>       80:31699/TCP    1m

What you expected to happen:
The nodePort section in Services doc indicates nodePort should be visible on all nodeIPs.

In my case, not all nodeIPs are responding to requests on dashboard's nodePort 31699 and forwarding them to dashboard pod.
Only the node (or minion) hosting the pod seems to respond to the browser requests. The other nodes (or minions) do not respond.

How to reproduce it (as minimally and precisely as possible):

_From knode-1 (a minion):_

$ sudo docker ps -a | grep dashboard

_curl access to the dashboard outside the cluster:_

The same behavior is reproducible on RHEL 7.3.
