Yu-Ju Hong 5863f2a0a5 kubelet: reduce logging frequency for sync loop

Lantao Liu a35220c321 cleanup pod_workers_test.go to use general runtime interface 2015-11-04 16:55:25 -08:00
Tim St. Clair 858126b42a Clean up static/mirror pod status logic 
- status.Manager always deals with the local (static) pod, but gets the
  mirror pod when syncing
  - This lets components like the probe workers ignore mirror pods

Yu-Ju Hong b734155954 Clean up housekeeping routine in kubelet 
Now that kubelet checks sources seen correctly, there is no need to enforce the
initial order of pod updates and housekeeping. Use a ticker for housekeeping to
simplify the code.

Yu-Ju Hong 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.

Clayton Coleman 2335bfa351 Allow Docker container logs to be tail'd and follow'd 
Relaxes the very very ancient restriction we put in place to keep the
original API surface area PR small. Better to be consistent with actual
expected use of tail.

Madhusudan.C.S 9c4424f0bd Report out of disk as a node condition when node goes out of disk. 
Define a new out of disk node condition and use it to report when node
goes out of disk.

Make a copy of loop range clause variable in node listers so that it
is available outside the for loop.

Also update/implement unit tests.
