* 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
* Examples which install CoreOS to disk should reference
a CoreOS install image from bootcfg assets to speed up
installs and improve the offline use-case
* Update scripts/get-coreos to download and verify the
CoreOS install image
* Update CoreOS version to get rkt 1.2.1->1.6.0 improvements
for running the kubelet wrapper in Kubernetes clusters
* Update CoreOS version for other clusters so users only need
to download one cached version of assets to run examples
* Match machines by MAC address in examples
* Re-use the MAC address to assign static networkd configs
where needed.
* UUID is useful to uniquely identify a machine (unlike MAC)
but many users had difficulty finding the network device name
to use in static networkd configs. Selecting by MAC reduces
the potential for user error here.
* bootkube clusters work with bootkube 5c1efe3ac61e270
* Copy bootkube generated assets and executable to any master
* Change hosts to use kubelet client certificate instead of token
* Update bootkube deployment documentation
