* Allow groups of workers to be defined and joined to
a cluster (i.e. worker pools)
* Move worker resources into a Terraform submodule
* Output variables needed for passing to worker pools
* Add usage docs for AWS worker pools (advanced)
* Set defaults for internal worker module's count,
machine_type, and os_image
* Allow "pools" of homogeneous workers to be created
using the google-cloud/kubernetes/workers module
* Template terraform-render-bootkube's multi-line kubeconfig
output using the right indentation
* Add `kubeconfig` variable to google-cloud controllers and
workers Terraform submodules
* Remove `kubeconfig_*` variables from google-cloud controllers
and workers Terraform submodules
* Upcoming releases may begin to use features that require
the `terraform-provider-ct` plugin v0.2.1
* New users should use `terraform-provider-ct` v0.2.1. Existing
users can safely drop-in replace their v0.2.0 plugin with v0.2.1
as well (location referenced in ~/.terraformrc).
* See https://github.com/poseidon/typhoon/pull/145
* Set Kubelet search path for flexvolume plugins
to /var/lib/kubelet/volumeplugins
* Add support for flexvolume plugins on AWS, GCE, and DO
* See 9548572d98 which added flexvolume support for bare-metal
* Remove PersistentVolumeLabel admission controller flag
* Switch Deployments and DaemonSets to apps/v1
* Minor update to pod-checkpointer image version
* 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
* Deployments now belong to the apps/v1 API group
* DaemonSets now belong to the apps/v1 API group
* RBAC types now belong to the rbac.authorization.k8s.io/v1 API group
* Add flannel service account and limited RBAC cluster role
* Change DaemonSets to tolerate NoSchedule and NoExecute taints
* Remove deprecated apiserver --etcd-quorum-read flag
* Update Calico from v3.0.1 to v3.0.2
* Add Calico GlobalNetworkSet CRD
* https://github.com/poseidon/terraform-render-bootkube/pull/44
* Change service discovery to relabel jobs to align with
rule expressions in upstream examples
* Use a separate service account for prometheus instead
of granting roles to the namespace's default
* Use a separate service account for node-exporter
* Update node-exporter and kube-state-metrics exporters
* Update CLUO from v0.4.1 to v0.5.0
* Earlier versions of CLUO fail to drain nodes on Kubernetes 1.9
so nodes drain one at a time repeatedly and Container Linux OS
updates are not applied to nodes.
* Check current OS versions via `kubectl get nodes --show-labels`
