a4816b3bcb Make kublet/util/format.go a separate package 
The formatting function is used often in logging. This improves the readability
by shortening the length of the call. Also change the fomartted string to
include the pod UID.

e6df0b1a24 Convert validation to use FieldPath 
Before this change we have a mish-mash of ways to pass field names around for
error generation.  Sometimes string fieldnames, sometimes .Prefix(), sometimes
neither, often wrong names or not indexed when it should be.

Instead of that mess, this is part one of a couple of commits that will make it
more strongly typed and hopefully encourage correct behavior.  At least you
will have to think about field names, which is better than nothing.

It turned out to be really hard to do this incrementally.

Addresses a version skew issue where the last condition status is always
evaluated as the NodeReady status. As a workaround force the NodeReady
condition to be the last in the list of node conditions.

ac778e8203 Adjust the sync/backoff period 
Set resyncInterval to one minute now that we rely on the generic pleg to trigger
pod syncs on container events. When there is an error during syncing, pod
workers need to wake up sooner to retry. Set the sync error backoff period to
10 second in this case.

bc6414a873 kubelet: add a generic pod lifecycle event generator 
This change introduces pod lifecycle event generator (PLEG), and adds a generic

container-runtime-agnostic. Both docker and rkt are changed to use generic
PLEG.

67cfed5bf3 Don't wait for sync to update readiness 
Push status updates as soon as readiness state changes for containers,
rather than waiting for the sync loop to update the status. In
particular, this should help new containers to come online faster.

Additionally, consolidates prober test helpers into a single file.

d519741e1b kubelet: Fallback to api server for pod status 
This commit fixes getting the logs from complete/failed pods after

1e88a682da Add liveness/readiness probe parameters 
- PeriodSeconds - How often to probe
- SuccessThreshold - Number of successful probes to go from failure to success state
- FailureThreshold - Number of failing probes to go from success to failure state

This commit includes to changes in behavior:

1. InitialDelaySeconds now defaults to 10 seconds, rather than the
kubelet sync interval (although that also defaults to 10 seconds).
2. Prober only retries on probe error, not failure. To compensate, the
default FailureThreshold is set to the maxRetries, 3.

b2c2d617cf Label nodes with Zone information, if available 
This lays the groundwork for simple multizone capabilities.

In a cloud environment, nodes are typically created by the kubelet
registering with the API server.  When creating a new node, we now query
the cloudprovider to see if it can provide Zone information, and if so
we add some well-known labels to the Node we are creating.

2eb17df46b kubelet: independent pod syncs and backoff on error 
Currently kubelet syncs all pods every 10s. This is not preferred because
 * Some pods may have been sync'd recently.
 * This may cause all the pods to be sync'd at once, causing undesirable
   CPU spikes.

This PR replaces the global syncs with independent, periodic pod syncs. At the
end of syncing, each pod worker will enqueue itslef with a future timestamp (
current time + sync interval), when it will be due for another sync.
 * If the pod worker encoutners an sync error, it may requeue with a different
   timestamp to retry sooner.
 * If a sync is triggered by the update channel (events or spec changes), the
   pod worker would enqueue a new sync time.

This change is necessary for moving to long or no periodic sync period once pod
lifecycle event generator is completed. We will still rely on the mechanism to
requeue the pod on sync error.

This change also makes sure that if a sync does not succeed (either due to
real error or the per-container backoff mechanism), an error would be propagated
back to the pod worker, which is responsible for requeuing.

a263c77b65 Refactor liveness probing 
This commit builds on previous work and creates an independent
worker for every liveness probe. Liveness probes behave largely the same
as readiness probes, so much of the code is shared by introducing a
probeType paramater to distinguish the type when it matters. The
circular dependency between the runtime and the prober is broken by
exposing a shared liveness ResultsManager, owned by the
kubelet. Finally, an Updates channel is introduced to the ResultsManager
so the kubelet can react to unhealthy containers immediately.

5abdfcdfe6 kubelet: fix all sources ready condition 
The current implementation considers a source seen when it receives a SET at
kubelet/config/config.go. However, the main kubelet sync loop may not have
received the pod update from the source via the channel. This change ensures
that kubelet would consider all sources are ready only after the sync loop has
seen all the sources.

bf2decce81 Add NotReadyAddresses to Endpoints 
In many cases clients may wish to view not ready addresses for endpoints
in order to do set membership prior to a pod being ready. For instance,
a pod that uses the service endpoints to connect to other pods under
the same service, but does not want to signal ready before it has
contacted at least a minimal number of other pods.

This is backwards compatible with old servers and clients. There is
an additional cost in size of endpoints before services ramp up, which
will add minor CPU and memory use for services that have a significant
number of pods which have not become ready.

PR #13293 added a safety check to not remove a pod directory if the child
volumes directory is not empty. This logic is faulty because kubelet may have
directory structures podUID/volumes/volumeKind/volumeName. E.g.,
`056db95d-50ee-11e5-a2e4-42010af0ba1d/volumes/kubernetes.io~empty-dir/default-token-al3r2`

b906e34576 kubelet: trigger pod workers independently 
Currently, whenever there is any update, kubelet would force all pod workers to
sync again, causing resource contention and hence performance degradation.

This commit flips kubelet to use incremental updates (as opposed to snapshots).
This allows us to know what pods have changed and send updates to those pod
workers only. The `SyncPods` function has been replaced with individual
handlers, each handling an operation (ADD, REMOVE, UPDATE). Pod workers are
still triggered periodically, and kubelet performs periodic cleanup as well.

This commit also spawns a new goroutine solely responsible for killing pods.
This is necessary because pod killing could hold up the sync loop for
indefinitely long amount of time now user can define the graceful termination
period in the container spec.

This is necessary because coreos comes with rkt installed, and if we want to use a different version
we need some way to avoid the default one.

0c84b837cf kubelet: switch to using pod UID as the key in status manager 
We chose to use podFullName (name_namespace) as key in the status manager
because mirror pod and static pod share the same status. This is no longer
needed because we do not store statuses for static pods anymore (we only
store statuses for their mirror pods). Also, reviously, a few fixes were
merged to ensure statuses are cleaned up so that a new pod with the same
name would not resuse an old status.

This change cleans up the code by using UID as key so that the code would
become less brittle.

780accb3ba Kubelet should garbage collect dead pods 
The sync loop should check for terminated pods that are no longer
running and clear them. The status loop should never write status
if the pod UID changes. Mirror pods should be deleted immediately
rather than gracefully.

89f1f3b1b8 Alter graceful deletion to not use TTL 
Avoid TTL by deleting pods immediately when they aren't
scheduled, and letting the Kubelet delete them otherwise.

Ensure the Kubelet uses pod.Spec.TerminationGracePeriodSeconds
when no pod.DeletionGracePeriodSeconds is available.

01f3785426 Add status.podIP as a valid downward API target 
Getting the public IP a container is supposed to use is O(hard),
and usually involves ugly gyrations in python or with interfaces.
Using the downward API means that the IP Kube is announcing to
other endpoints is also visible inside the container for pods to
identify themselves.

56f4605f47 kubelet: refactor SyncPods for better readability 
Eventually we would like to replace the all-encompassing SyncPods function with
more well-defined, smaller functions. This would not only help with the
readability and profiling of the code, it'd also set in motion for the plans to
trigger pod worker individually based on the content of the pod updates.

This commit serves as the first step of that, while avoiding breaking all unit
tests by preserving the SyncPods function for the time being.

they upgrade DNS.  Versions of kube2sky >= 1.6 support both old and new style

kubernetes v1.0 release.

72ee028cab 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.

2bf0646c76 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.

050b8ba60b 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).

25668ccc11 Kubelet: remove the getPodstatus method 
Pod statuses are periodically writtien to the status manager, and status
manager sets the start time of the pod. All non-status-modifying code should
perform cache lookup and should not attempt to generate pod status on its own.

a2d04a84de kubelet: filter out terminated pods before rejecting pods 
Currently, kubelet doesn't filter out terminated pods before determining whether
a pod fits. This could lead to duplicated events for rejecting the pods. This
change fixes that.

This change also groups all related pod fitness checking functions into one
function to improve readability.
