Yu-Ju Hong f96a8d0935 Kubelet: record the initial pod processing latency

Justin Santa Barbara 27b02d0913 Fix kubelet unit test; populate NodeName

as well as hostname, because we bypass the functions that normally
do this for us.

Andy Goldstein 7748a02e37 Eliminate possible infinite loop in exec
If a user starts an exec session with a shell and leaves it idle long
enough, they will eventually hit the Kubelet's HTTP server's read/write
timeout of 5 minutes. At this time, the StartExec call to Docker exits,
but if the user requested a TTY, the exec'd process does not exit.
After StartExec finishes, we try to determine the exit code of the
exec'd process, but in this case, we'll never get it. This change exits
the loop after 5 tries if the process is still running.

Tim Hockin a826529573 Insert 'svc' into the DNS search paths
Fixes #8569.

This requires the DNS server to be running kube2sky v1.6 or higher (part of
release 0.18).  Users with older kube2sky MUST NOT update to this kubelet until
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.

Clayton Coleman 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.

Kris f4e2c738f6 Delete deprecated API versions
pkg/service:

There were a couple of references here just as a reminder to change the
behavior of findPort. As of v1beta3, TargetPort was always defaulted, so
we could remove findDefaultPort and related tests.

pkg/apiserver:

The tests were using versioned API codecs for some of their encoding
tests. Necessary API types had to be written and registered with the
fake versioned codecs.

pkg/kubectl:

Some tests were converted to current versions where it made sense.

Yu-Ju Hong 044894665d Delete TestSyncPodsDeletes in kubelet_test.go
This test verifies that kubelet doesn't kill non-kubelet-managed containers.
This is obsolete now since container runtime provides only the KillPod
function, and has no support for killing a container.

Victor Marmol ddec34a000 Have the ContainerManager create a system container.
The system container is a resource-only container which contains all
non-kernel processes that are not already part of a container. This will
allow monitoring of their resource usage and limiting it (eventually).

Yu-Ju Hong 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.

Yu-Ju Hong 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).

Yu-Ju Hong 25668ccc11 Kubelet: remove the getPodstatus method

Yu-Ju Hong ab5e0e0b5c Use the full hostname for mirror pod name.
This change appends the full hostname to the mirror pod name (instead of taking
the first token) so that if the hostname is overriden, we'd not be creating
unncessary name conflicts. An example would be that a user overrides the
hostnames to be "127.0.0.1" and "127.0.0.2", and both of them were resolved to
"127" for the mirror pod name suffix.

Also, because `uname -n` could return a FQDN or not, this change takes only
the first token of it as the hostname for consistency.

Yu-Ju Hong c075719f05 Kubelet: fix the runtime cache to not cache the stale pods
If a pod worker sees stale pods from the runtime cache which were retrieved
before their last sync finished, it may think that the pod were not started
correctly, and attemp to fix that by killing/restarting containers.
There are two issues that may cause runtime cache to store stale pods:
  1. The timstamp is recorded *after* getting the pods from the container
     runtime. This may lead the consumer to think the pods are newer than they
     actually are.
  2. The cache updates are triggered by many goroutines (pod workers, and the
     updating thread). There is no mechanism to enforece that the cache would
     only be updated to newer pods.

This change fixes the above two issues by making sure one always record the
timestamp before getting pods from the container runtime, and updates the
cached pods only if the timestamp is newer.

This change makes rkt to run only docker image for now,
which enables us to test with all existing pods.
