I'm trying to use kube-ui, but I got a 503 error in dashboard. Looking a solution for it I found that is caused by cAdvisor and it is embedded in kubelets. But, I don't know why this is occurring. I'm starting my hyperkube kubelet using this command:

`docker run --net=host -d -v /var/run/docker.sock:/var/run/docker.sock  gcr.io/google_containers/hyperkube:v1.0.7 /hyperkube kubelet --api_servers=http://localhost:8080 --v=2 --address=0.0.0.0 --enable_server --hostname_override=127.0.0.1 --allow-privileged=true --cadvisor-port=4194 --config=/etc/kubernetes/manifests-multi`

And kube-ui:

kubectl create -f cluster/addons/kube-ui/kube-ui-rc.yaml
kubectl create -f cluster/addons/kube-ui/kube-ui-svc.yaml

I tried too, run a cadvisor container and then the dashboard appeared, but master and slave graphics information are the same. Command line that I used:

sudo docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=4194:8080 \
--detach=true \
--name=cadvisor \
google/cadvisor:latest
