they upgrade DNS. Versions of kube2sky >= 1.6 support both old and new style
names. Old style names are deprectaed and will be removed around the time of
kubernetes v1.0 release.

Gracefully delete pods from the Kubelet
...
This commit wires together the graceful delete option for pods
on the Kubelet. When a pod is deleted on the API server, a
grace period is calculated that is based on the
Pod.Spec.TerminationGracePeriodInSeconds, the user's provided grace
period, or a default. The grace period can only shrink once set.
The value provided by the user (or the default) is set onto metadata
as DeletionGracePeriod.
When the Kubelet sees a pod with DeletionTimestamp set, it uses the
value of ObjectMeta.GracePeriodSeconds as the grace period
sent to Docker. When updating status, if the pod has DeletionTimestamp
set and all containers are terminated, the Kubelet will update the
status one last time and then invoke Delete(pod, grace: 0) to
clean up the pod immediately.

Kubelet: do not remove directories of terminated pods
...
We recently changed `SyncPods` to filter out terminated pods at the beginning
for two reasons:
* performance: kubelet no longer keeps goroutines to checks containers for
terminated pods.
* correctness: kubelet relies on inspecting dead containers to generate
pod status. Because dead containers may get garbage collected and
kubelet does not have checkpoints yet, syncing terminated pod could
lead to modifying the status of a terminated pod.
However, even though kubelet should not *sync* the terminated pods, it
should not attempt to remove the directories and volumes for such
pods as long as they have not been deleted. This change fixes aggresive
directory removal by passing all pods (including terminated pods) to the
cleanup functions.

Kubelet: move active deadline check to per pod worker
...
Per-pod workers have sufficient knowledge to determine whether a pod has
exceeded the active deadline, and they set the status at the end of each sync.
Move the active deadline check to generatePodStatus so that per pod workers
can update the pod status directly. This eliminates the possibility of a race
condition where both SyncPods and the pod worker are updating the status, which
could lead to temporary erratic pod status behavior (pod phase: failed ->
running -> failed).

Kubelet: replace DockerManager with the Runtime interface
...
This change instructs kubelet to switch to using the Runtime interface. In order
to do it, the change moves the Prober instantiation to DockerManager.
Note that most of the tests in kubelet_test.go needs to be migrated to
dockertools. For now, we use type assertion to convert the Runtime interface to
DockerManager in most tests.

work in a non-Docker runtime.

kubelet: filter out terminated pods in SyncPods
...
Once a pod reaches a terminated state (whether failed or succeeded), it should
not transit out ever again. Currently, kubelet relies on examining the dead
containers to verify that the container has already been run. This is fine
in most cases, but if the dead containers were garbage collected, kubelet may
falsely concluded that the pod has never been run. It would then try to restart
all the containers.
This change eliminates most of such possibilities by pre-filtering out the pods
in the final states before sending updates to per-pod workers.

Kubelet: a step towards to better encapsulation of docker functions
...
We want to stop leaking more docker details into kubelet, and we also want to
consolidate some of the existing docker interfaces/structs. This change creates
DockerManager as the new home of some functions in dockertools/docker.go. It
also absorbs containerRunner. In addition, GetDockerPodStatus is renamed to
GetPodStatus with the entire pod passed to it so that it is simialr to the what
is defined in the container Runtime interface.
Eventually, DockerManager should implement the container Runtime interface, and
integrate DockerCache with a flag to turn on/off caching. Code in kubelet.go
should not be using docker client directly.

Fixing a lot of string formatting issues with regards to:
...
* Improper format specifier (e.g. %s for bools or %s for ints)
* More or less parameters than format specifiers
* Not calling a formatting function when it should have (e.g. Error() instead of Errorf())
