Andy Goldstein 51251ef5c1 Skip probe if container ID not yet set 
If the container status exists but the container hasn't been created yet, it won't have an ID.
Have the probe wait for a valid status if the container ID is not yet set; otherwise, you'll see the
following cryptic log message from runtime.go: invalid container ID: "".

Dan Williams 6248939e11 Push responsibility for bridge-nf-call-iptables to kubelet network plugins 
bridge-nf-call-iptables appears to only be relevant when the containers are
attached to a Linux bridge, which is usually the case with default Kubernetes
setups, docker, and flannel.  That ensures that the container traffic is
actually subject to the iptables rules since it traverses a Linux bridge
and bridged traffic is only subject to iptables when bridge-nf-call-iptables=1.

But with other networking solutions (like openshift-sdn) that don't use Linux
bridges, bridge-nf-call-iptables may not be not relevant, because iptables is
invoked at other points not involving a Linux bridge.

The decision to set bridge-nf-call-iptables should be influenced by networking
plugins, so push the responsiblity out to them.  If no network plugin is
specified, fall back to the existing bridge-nf-call-iptables=1 behavior.

Yu-Ju Hong a68f534264 kubelet: fix duplicated status updates at pod cleanup 
cleanupTerminatedPods is responsible for checking whether a pod has been
terminated and force a status update to trigger the pod deletion. However, this
function is called in the periodic clenup routine, which runs every 2 seconds.
In other words, it forces a status update for each non-running (and not yet
deleted in the apiserver) pod. When batch deleting tens of pods, the rate of
new updates surpasses what the status manager can handle, causing numerous
redundant requests (and the status channel to be full).

This change forces a status update only when detecting the DeletionTimestamp is
set for a terminated pod. Note that for other non-terminated pods, the pod
workers should be responsible for setting the correct status after killling all
the containers.

Clayton Coleman ae2f6a833a Reduce volume of logs generated at v(3) 
Node controller is generating a huge amount of logging at v(3) that is
more appropriate for v(5). Split the log into two levels and ensure it
also ends up on one line (so grep works).

The pod manager generates a v(4) pod output on sync that always contains
a newline - since the size of the pod is so excessive in output, kick it
to v(5) for deep debugging (we're pretty happy with this loop).

Yu-Ju Hong 3072754c8b Avoid unnecessary GET request when updating pod status 
When sending out an pod status update, kubelet

GETs the pod from the apiserver
Terminates if the apiserver returns an not found error; otherwise, proceed to
to update.
Even after a pod has been deleted, there might still be queued up updates for
the pod. This leads to expensive, unncessary GET operations. The situation is
worse when there are batch creation/deletion of a significant number of pods
(e.g., E2E tests), leaving many updates in the queue.

This change checks whether a pod exists before GET the pod from the apiserver
to avoid redundant GETs.

Jan Chaloupka 392fc6668f Jittering periods of some kubelet's sync loops: 
- pod_workers: pod syncing
- prober workers: container syncing

In order to synchronize the current state of Kubernetes's objects (e.g. pods, containers, etc.),
periodic synch loops are run. When there is a lot of objects to synchronize with,
loops increase communication traffic. At some point when all the traffic interfere cpu usage curve
hits the roof causing 100% cpu utilization.

To distribute the traffic in time, some sync loops can jitter their period in each loop
and help to flatten the curve.

Jan Safranek e90de3f985 Fixed cleanup of persistent volumes. 
Kubelet.cleanupOrphanedVolumes() compares list of volumes mounted to a node
with list of volumes that are required by pods scheduled on the node
("scheduled volume").

Both lists should contain real volumes, i.e. when a pod uses
PersistentVolumeClaim, the list must contain name of the bound volume instead
of name of the claim.

Clayton Coleman d6d4a17db6 Allow clients to request most recent container logs 
Many users attempt to use 'kubectl logs' in order to find the logs
for a container, but receive no logs or an error telling them their
container is not running. The fix in this case is to run with '--previous',
but  this does not match user expectations for the logs command.

This commit changes the behavior of the Kubelet to return the logs of
the currently running container or the previous running container unless
the user provides the "previous" flag. If the user specifies "follow"
the logs of the most recent container will be displayed, and if it is
a terminated container the logs will come to an end (the user can
repeatedly invoke 'kubectl logs --follow' and see the same output).

Clean up error messages in the kubelet log path to be consistent and
give users a more predictable experience.

Have the Kubelet return 400 on invalid requests

Ken Robertson fff8a7c371 kubelet: Update engine version parsing to handle semantic versioning 
This updates the dockertools.dockerVersion to use a semantic versioning
library to more gracefully support engine versions which include
additional version fields.

Previously, go-dockerclient's APIVersion struct was use which only
handles plain numeric x.y.z version strings. With #19675, the library
was now used on the Docker engine string, however it is possible for the
engine string to include include additional information for beta, rc, or
distro specific builds.

This PR also enables the TestDockerRuntimeVersion test which was
previously just a FIXME and updates it to pass, and be used to test the
version string that cause #20005.

This negates the need for fsouza/go-dockerclient#451, since even with
that change, if a user was running Docker 1.10.0-rc1, this would cause
the kubelet to report it as simply 1.10.0.
