* Improve the workers "round-robin" DNS FQDN that is created
with each cluster by adding AAAA records
* CNAME's resolving to the DigitalOcean `workers_dns` output
can be followed to find a droplet's IPv4 or IPv6 address
* The CNI portmap plugin doesn't support IPv6. Hosting IPv6
apps is possible, but requires editing the nginx-ingress
addon with `hostNetwork: true`
* Adjust firewall rules, security groups, cloud load balancers,
and generated kubeconfig's
* Facilitates some future simplifications and cost reductions
* Bare-Metal users who exposed kube-apiserver on a WAN via their
router or load balancer will need to adjust its configuration.
This is uncommon, most apiserver are on LAN and/or behind VPN
so no routing infrastructure is configured with the port number
* Stop maintaining Kubernetes Dashboard manifests. Dashboard takes
an unusual approch to security and is often a security weak point.
* Recommendation: Use `kubectl` and avoid using the dashboard. If
you must use the dashboard, explore hardening and consider using an
authenticating proxy rather than the dashboard's auth features
* Be sure docs and examples list Container Linux versions that
have been patched for Meltdown just in case someone copy-pastes
or sees them as recent versions
* Adapt the coreos/prometheus-operator alerting rules for Typhoon,
https://github.com/coreos/prometheus-operator/tree/master/contrib/kube-prometheus/manifests
* Add controller manager and scheduler shim services to let
prometheus discover them via service endpoints
* Fix several alert rules to use service endpoint discovery
* A few rules still don't do much, but they default to green
