some work in progress notes, in preparation for an edit to support packet.net and Kubernetes 1.9:

• kubeadm-init should pick up stable-1.9 instead of stable-1.7
• use $PRIVATE-IP for the admin address, and then use Doorman for a VPN into the private net
• the pod-network-cidr and IPALLOC_RANGE will change (details tbd)
• weave installs more easily on 1.9 without the need for the sed step
