Yu-Ju Hong 2816c9df78 config_test: clean up unused function arguements 2015-09-11 17:18:29 -07:00
Yu-Ju Hong 69c3aa0872 Fix source annotation in kubelet 
kubelet relies on source annotation to distinguish pods from different sources.
It should always annotate the source when receiving the pod to avoid any
confusion. This commit fixes that and also make sure we don't overwrite the
first seen time.

Tim St. Clair 1f91fffb57 Move kubelet.statusManager to status.Manager 
This refactor is in preparation for moving more state handling to the
status manager. It will become the canonical cache for the latest
information on running containers and probe status, as part of the
prober refactoring.

Bobby Abbott 9a5f43e16d Kubelet#GetNode now uses GetNodeInfo instead of List 
Both GetNode and the cache.ListWatch listfunc in the
kubelet package call List unnecessary.

GetNodeInfo is sufficient for GetNode and makes looping
through a list of nodes to check for a matching name
unnecessary.

Andy Goldstein c83786979c Various exec fixes 
If stdin is noninteractive, the io.Copy from stdin to remoteStdin will
unblock when it finishes reading from stdin. In this case, make sure to
close remoteStdin so the server knows the client won't be sending any
more data. This ensures that the remote process terminates. For example:

echo foo | kubectl exec -i <pod> -- cat

Without this change, the `cat` process never terminates and `kubectl
exec` hangs.

Fix interactive exec sessions hanging after you type 'exit'.

Add e2e test to cover noninteractive stdin: `echo a | kubectl exec -i <pod>
cat`

Add e2e test to cover psuedo-interactive stdin: `kubectl exec -i <pod> bash`

Prep for sending multiple data frames over multiple streams in remote command
test, which is more likely to find flakes (requires bump of spdystream
once an issue with the frame worker queues not being fully drained when
a goaway frame is received).

Yu-Ju Hong 08ec796995 kubelet: remove orphaned pod directories properly 
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`

This change fixes that by properly listing all volumes under a pod.

Yu-Ju Hong 13b268b378 kubelet: define the minimum housekeeping period 
Before, kubelet performs global cleanup tasks every iteration. After the
PR #13003, kubelet performs the tasks on every sync internval (10 seconds).
This PR decouples the housekeeping period with the sync internval to ensure
that kubelet cleans up promptly, while not too often (no more than once every
minimum housekeeping period).

Yu-Ju Hong 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.

Yu-Ju Hong 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.

Clayton Coleman 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.
 2015-08-18 09:08:44 -04:00
Clayton Coleman 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.

Clayton Coleman 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.

Yu-Ju Hong 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.

Since it takes a while (1-2mins) for kubelet to pulling a big image

This commit introduces a "pulling" event, and inserts it before the
kubelet starts to pull an image.

Yu-Ju Hong d6ff297a1f Kubelet: stop logging "Error on reading termination-log..." messages 
If a pod was deleted and the associated volumes/directory were removed, there
could be a window where the pod worker is still active. If the pod worker tries
to inspect the logs, such an error would be logged. Since the pod has been
deleted, such error messages are meaningless.

This change stops logging this error, but stores the error string in the pod
status. The pod status will be updated for pods that are still alive, and will
be discarded eventually for deleted pods.

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

Justin Santa Barbara df87470ecf Allow cloud providers to return a node identifier different from the hostname 2015-06-18 12:40:05 -07:00
Justin Santa Barbara dee8d4b90b For kubelet, differentiate between the nodeName and the hostname 
This will allow us to use a nodeName that is not the hostname,
for example on clouds where the hostname is not the natural identifier
for a node.
