* Discontinue using Matchbox's Container Linux Config features
* Flatcar Linux OS now supports Ignition v2.13+ which means it
can accept Ignition v3.x spec's, like Fedora CoreOS. Matchbox
supports this by serving Ignition documents directly
* Users of the poseidon/matchbox Terraform provider can pass
a `matchbox_profile` `raw_ignition` contents with the desired
Ignition v3.3 spec
* Users of the poseidon/ct Terraform provider can write Butane
Config YAML, perform templating, and render an Ignition document
using either the fcos or the flatcar variant
* Refactor examples to boot provision minimal hosts
with Fedora CoreOS or Flatcar Linux
* Remove the etcd3 cluster example or other specific
kinds of hosts
* Update script get-fedora-coreos
* Remove script get-coreos
* Use the container linux update operator to coordinate reboots
* Stop using locksmithd for reboot coordination
* etcd TLS assets now only need to be distributed to controller
nodes which are etcd peers
* 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
* Use the same k8s-controller and k8s-worker profiles
whether booting a live cluster or installing to disk
* Exta root=/dev/sda kernel arg during install is fine
* simple example just network boots CoreOS machines
* simple-install example just network boots and installs CoreOS
* Simple examples don't do much provisioning, except adding pubkeys
* Self-hosted Kuberntes api-server comes up without a hostname
override and detects the hostname it should use from `uname -n`
* kube-apiserver name must correspond to routable kubelet
hostname-override
* Provision /etc/hostname with the FQDN so `uname -n` can be
used by Kubernetes (until NODE_NAME is avail. in k8s 1.4)
* Use DNS names to refer to nodes in etcd examples to mirror
production
* Add dnsmasq.conf files for metal0 (rkt) and docker0 examples
which include static MAC->IP and Name->IP mappings
* Remove the etcd-docker example cluster, no longer needed
* Clusters which install to disk auto-update so this bump just
changes the "starting" version. Deployed alpha clusters should
already be using 1109.1.0.
* scp kubeconfig to hosts rather than insecurely distributing
credentials within Ignition configs. This is also easier than
copy-pasting k8s secrets into machine metadata (slow).
* Self-hosted Kubernetes machine configurations can be versioned
without containing Kubernetes credentials
* Use path-based activiation for the host kubelet
* Update from Kubernetes v1.2.2 to v1.3.0-alpha.5_coreos.0.
* Update host kubelet flags accordingly
