There is a workaround implemented by Kubernetes (https://github.com/kubernetes/kubernetes/blob/release-1.6/pkg/kubelet/network/kubenet/kubenet_linux.go#L345) and other Docker-based solutions (flynn: https://github.com/flynn/flynn/commit/9d94ea8e2ad7a626f74ff03cb82e8d0efe1b42b5). The fix is putting the docker0 bridge in promiscuous mode by executing `ip link set docker0 promisc on`.

Showing gateway for Docker bridge network: docker network inspect bridge -f "{{range .IPAM.Config}}{{.Gateway}}{{end}}"

All hosts should return the same gateway.

DEPRECATED as of 2017-06-27, see README here https://github.com/chrisurwin/rancher-rodeo

Prerequisites

• Machine with 8GB RAM, SSD – Run 1 rancher server and 3 nodes (change the RAM size)
• Machine with 16GB RAM NVME Disk – Run 1 Rancher Server and 3 VMS
• 4 VMs running in Cloud (2GB each, ensure security group has UDP 500 & 4500, TCP 8080, 2049 & 80 open. Recommend all traffic on UDP and TCP allowed in local network)

Only run Docker 1.12.6 if you want the K8s demo to work!
