* 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
* Setting k8s_version via metadata gives the impression
it can be bumped and the cluster will operate with the
desired version. In reality, the k8s profiles change in
minor but important ways which we validate between k8s
releases. It should be part of the k8s profile Ignition.
* Split config.yaml files into JSON groups files
* Update examples to use folders of mountable groups files
* Stop reading groups from a -config config.yaml file
* Add RichGroup JSON <-> Protobuf Serialize Group
