Dalton Hubble f2f4deb8bb Change AWS default type from t2.small to t3.small
* T3 is the next generation general purpose burstable
instance type. Compared with t2.small, the t3.small is
cheaper, has 2 vCPU (instead of 1) and provides 5 Gbps
of pod-to-pod bandwidth (instead of 1 Gbps)

Dalton Hubble e0c032be94 Increase GCP TCP proxy apiserver backend timeout to 5 minutes
* On GCP, kubectl port-forward connections to pods are closed

* Increase the GCP apiserver backend service timeout from 1 minute
to 5 minutes to be more similar to AWS/Azure LB behavior

Dalton Hubble b6016d0a26 Disable Grafana login form, admin user can't be disabled
* Example manifests aim to provide a read-only dashboard visible

* Problem: Grafana always has an admin user, even with the user
management system disabled
* Disable the login form to prevent admin login

Dalton Hubble 42c523e6a2 Recommend switch from ~/.terraformrc to 3rd-party plugin dir

API (before falling back to the Kubelet read-only API that
is disabled on Typhoon clusters since
https://github.com/poseidon/typhoon/pull/324)
* Previously, pod-checkpointer checkpointed an initial set
of pods during bootstrapping so recovery from power cycling

Dalton Hubble e95b856a22 Enable CoreDNS loop and loadbalance plugins
* loop sends an initial query to detect infinite forwarding
loops in configured upstream DNS servers and fast exit with
an error (its a fatal misconfiguration on the network that
will otherwise cause resolvers to consume memory/CPU until
crashing, masking the problem)
* https://github.com/coredns/coredns/tree/master/plugin/loop
* loadbalance randomizes the ordering of A, AAAA, and MX records
in responses to provide round-robin load balancing (as usual,
clients may still cache responses though)

to internal IP's to work around some cloud providers not
resolving hostnames for instances (e.g. DO droplets)

Dalton Hubble 0e71f7e565 Ignore controller user_data changes to allow plugin updates
* Updating the `terraform-provider-ct` plugin is known to produce
a `user_data` diff in all pre-existing clusters. Applying the
diff to pre-existing cluster destroys controller nodes
* Ignore changes to controller `user_data`. Once all managed
clusters use a release containing this change, it is possible
to update the `terraform-provider-ct` plugin (worker `user_data`
will still be modified)
* Changing the module `ref` for an existing cluster and
re-applying is still NOT supported (although this PR
would protect controllers from being destroyed)

Dalton Hubble f034ef90ae Add DigitalOcean AAAA DNS records resolving to workers
* Improve the workers "round-robin" DNS FQDN that is created

* 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`

Dalton Hubble bc750aec33 Configure Heapster to source metrics from Kubelet authenticated API
* Heapster can now get nodes (i.e. kubelets) from the apiserver and
source metrics from the Kubelet authenticated API (10250) instead of
the Kubelet HTTP read-only API (10255)
* https://github.com/kubernetes/heapster/blob/master/docs/source-configuration.md
* Use the heapster service account token via Kubelet bearer token
authn/authz.
* Permit Heapster to skip CA verification. The CA cert does not contain
IP SANs and cannot since nodes get random IPs that aren't known upfront.
Heapster obtains the node list from the apiserver, so the risk of
spoofing a node is limited. For the same reason, Prometheus scrapes
must skip CA verification for scraping Kubelet's provided by the apiserver.
* https://github.com/poseidon/typhoon/blob/v1.12.1/addons/prometheus/config.yaml#L68
* Create a heapster ClusterRole to work around the default Kubernetes
`system:heapster` ClusterRole lacking the proper GET `nodes/stats`
access. See https://github.com/kubernetes/heapster/issues/1936
