Kubeadm why doesn't my node appear even though the cubelet says it joined?

Question

I am creating a Kubernetes deployment using autoscale groups and Terraform. The host cube node is behind the ELB to get some reliability in the event of something wrong. The ELB has a set of health checks for tcp 6443and tcp listeners for 8080, 6443, and 9898. All instances and the load balancer belong to the security group, which allows all traffic between group members, as well as public traffic from the NAT gateway address. I created my AMI using the following script (from the getting started guide) ...

# curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
# cat <<EOF > /etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
EOF
# apt-get update
# # Install docker if you don't have it already.
# apt-get install -y docker.io
# apt-get install -y kubelet kubeadm kubectl kubernetes-cni

I use the following user data scripts ...

cube master

#!/bin/bash
rm -rf /etc/kubernetes/*
rm -rf /var/lib/kubelet/*

kubeadm init \
  --external-etcd-endpoints=http://${etcd_elb}:2379 \
  --token=${token} \
  --use-kubernetes-version=${k8s_version} \
  --api-external-dns-names=kmaster.${master_elb_dns} \
  --cloud-provider=aws
until kubectl cluster-info
do
  sleep 1
done
kubectl apply -f https://git.io/weave-kube

kube node

#!/bin/bash
rm -rf /etc/kubernetes/*
rm -rf /var/lib/kubelet/*

until kubeadm join --token=${token} kmaster.${master_elb_dns}
do
  sleep 1
done

Node join complete:
* Certificate signing request sent to master and response
  received.
* Kubelet informed of new secure connection details.

Run 'kubectl get nodes' on the master to see this machine join.
