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This is obsolete now since container runtime provides only the KillPod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).

Federico Simoncelli 2f503c57a5 nodecontroller: improve node status event recording 
This patch substitutes the misleading reason "unknown" for the event
recording. For symmetry with kubelet's message "online" the conditions
Unknown and False are reported as "offline".

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).
 2015-05-18 10:52:41 -07:00
Yu-Ju Hong 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.

Yu-Ju Hong 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.

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.

dockertools. For now, we use type assertion to convert the Runtime interface to
DockerManager in most tests.
