* Upgrade to bootkube v0.4.5
* Enable TLS for experimental self-hosted etcd
* Upstream manifest generation changes modify the flannel
Daemonset, switch several control plane components to run
as non-root, and add an explicit UpdateStrategy to the
control plane components
* Module "profiles" provides container-linux-install and
cached-container-linux-install Profiles
* Module bootkube accepts cached_install variable to determine
whether the cluster should install Container Linux from cache
or from the public download site (default)
* Static Kubernetes / rktnetes examples are no longer going to be
maintained by this repo or upgraded to Kubernetes v1.6. This is not
considered a deprecation bc the reference clusters are examples.
* Remove static Kubernetes cluster examples so users don't choose it
* Self-hosted Kubernetes (bootkube) is now the standard recommended
Kubernetes cluster configuration
* Calculate the required service IP values from the service CIDR
* These inputs were never truly customizable anyway since bootkube
start assumed the 1st, 10th, and 15th offsets for named services
* Use the dghubble/bootkube-terraform terraform module to generate
the exact same assets that `bootkube render` would
* Use terraform to automate the kubeconfig copy and bootkube start
* Removes the reuqirement to download a bootkube binary, render assets,
and manually copy assets to nodes
* Add an option to try experimental self-hosted etcd which uses
the etcd-operator to deploy an etcd cluster as pods atop Kubernetes
and disables the on-host etcd cluster
* When enabled, configure locksmithd to coordinate reboots through
self-hosted etcd
* Add matchbox_http_endpoint and matchbox_rpc_endpoint as variables
* Remove dghubble ssh public key from default
* Add a terraform.tfvars.example and gitignore terraform.tfvars
* Add container-linux-install profile to install Container Linux
* Add cached-container-linux-install profile to install Container Linux
from cached matchbox assets
Previously, the terraform readme was incomplete by only including
terraform plan and apply commands. Additionally, the readme was
updated to include instructions for updating the profiles module
source.
Fixes#502
* Terraform example typo's the port number in the etcd_endpoints
* Causes worker etcd-gateway to fail so Container Linux updates may
not been coordinated by locksmith
