* Change EBS volume type from `standard` ("prior generation)
to `gp2`. Prometheus alerts are tuned for SSDs
* Other platforms have fast enough disks by default
* Calico isn't viable on Digital Ocean because their firewalls
do not support IP-IP protocol. Its not viable to run a cluster
without firewalls just to use Calico.
* Remove the caveat note. Don't allow users to shoot themselves
in the foot
* Fix issue where worker firewall rules didn't apply to
additional workers attached to a GCP cluster using the new
"worker pools" feature (unreleased, #148). Solves host
connection timeouts and pods not being scheduled to attached
worker pools.
* Add `name` field to GCP internal worker module to represent
the unique name of of the worker pool
* Use `cluster_name` field of GCP internal worker module for
passing the name of the cluster to which workers should be
attached
* This reverts commit cce4537487.
* Provider passing to child modules is complex and the behavior
changed between Terraform v0.10 and v0.11. We're continuing to
allow both versions so this change should be reverted. For the
time being, those using our internal Terraform modules will have
to be aware of the minimum version for AWS and GCP providers,
there is no good way to do enforcement.
* 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
* 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
* 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
* 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
* Add explicit "providers" section to modules for Terraform v0.11.x
* Retain support for Terraform v0.10.4+
* Add migration guide from Terraform v0.10.x to v0.11.x for those managing
existing clusters (action required!)
* 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
* Allow kube-dns to respond to DNS queries with a custom
suffix, instead of the default 'cluster.local'
* Useful when multiple clusters exist on the same local
network and wish to query services on one another
