1) Install Ubuntu on nodes and set hostname and IP on all nodes

2) Prepare nodes. Run these commands as the root user on all nodes
	
	#turn off swap
	swapoff -a
	
	#install packages
	apt-get install -y ntp docker.io

	#configure ntp. set pool.ntp.org to your local or preferred server
	sed -i '/pool/d' /etc/ntp.conf
	echo 'server pool.ntp.org iburst' | tee -a /etc/ntp.conf
	service ntp restart

	#disable firewall
	sudo ufw disable 

3) Distribute ssh keys

	#copy existing ssh key pair to /root/.ssh/ on the master node or create a new ssh key pair with 
	ssh-keygen -t rsa -b 4096 -C "your_email@domain.com"
	#distribute the public key to each node with
	ssh-copy-id user@node

4) Instantiate RKE Kubernetes cluster with no CNI plugin

	#run these commands as root on the master node
	
	#cd and download rke binary
	cd /root/ ; wget https://github.com/rancher/rke/releases/download/v0.3.0/rke_linux-amd64

	#rename, chmod, move, test rke binary
	mv rke_linux-amd64 rke ; chmod +x rke ; mv rke /usr/bin ; rke --version
	
	#configure the cluster.yml using 'rke config'. 
	#set the following variables for each node and accept the default for all other variables
	
	rke config
	
	#Number of Hosts  				#enter the number of nodes in the cluster
	#SSH Address of Hosts 				#enter IP address for node
	#SSH User of host 				#enter root
	#Is host a Control Plane host 			#enter y for master node
	#Is host a Worker Host 				#enter y for worker node 
	#Is host an etcd host  				#enter y for master node
	#Override Hostname of host 			#enter hostname of node 
	#Network Plugin type 				#enter none
	#Service Cluster IP Range                       #enter 10.96.0.0/12
	#Cluster Network CIDR                           #enter 10.32.0.0/12
	#Cluster DNS Service IP                         #enter 10.96.0.3

	#run rke up to instantiate rke kubernetes cluster
	rke up

5) Install TungstenFabric 

	#run these commands as root on the master node

	#install kubectl
	sudo snap install kubectl --classic 

	#copy kubeconfig into place
	mkdir /root/.kube ; cp /root/kube_config_cluster.yml /root/.kube/config
	
	#label master nodes with the 'node-role.kubernetes.io/master=true' label. 
	#replace <MASTER_NODE_NAME> with the hostname of the master node
	kubectl label nodes <MASTER_NODE_NAME> node-role.kubernetes.io/master=true

	#add /var/lib/contrail/ports/vm to rke kubelet container ON ALL NODES
	docker exec -it kubelet mkdir -p /var/lib/contrail/ports/vm
	
	#install TungstenFabric via manifest. set <MASTER_NODE_IP> to the master node ip
	export K8S_MASTER_IP=<MASTER_NODE_IP> ; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; mkdir -pm 777 /var/lib/contrail/kafka-logs; curl https://raw.githubusercontent.com/Juniper/contrail-kubernetes-docs/master/install/kubernetes/templates/contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" >> /root/tf.yml ; kubectl apply -f /root/tf.yml

	#fix coredns
	kubectl get configmap -nkube-system coredns -o yaml >> /root/coredns-configmap.yaml
	export coredns_line="        forward . 10.47.255.253"
  	sed -i "s/.*forward.*/$coredns_line/" /root/coredns-configmap.yaml
        kubectl get deployment -nkube-system coredns -o yaml >> /root/coredns-deployment.yaml
	sed -i "/        livenessProbe:/,+9d" /root/coredns-deployment.yaml 
	sed -i "/        readinessProbe:/,+8d" /root/coredns-deployment.yaml
	kubectl apply -f /root/coredns-configmap.yaml
	kubectl apply -f /root/coredns-deployment.yaml

	#get pod status 
	kubectl get pods --all-namespaces -owide
	
	#for now it is safe to ignore analytics db crashloop
	#kube-system     contrail-analyticsdb-r6474                2/3     CrashLoopBackOff 	
		
	#get TungstenFabric status once all TungstenFabric pods are running
