Label nodes with Zone information, if available
...
This lays the groundwork for simple multizone capabilities.
In a cloud environment, nodes are typically created by the kubelet
registering with the API server. When creating a new node, we now query
the cloudprovider to see if it can provide Zone information, and if so
we add some well-known labels to the Node we are creating.

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

simplify the code.

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.

Refactor liveness probing
...
This commit builds on previous work and creates an independent
worker for every liveness probe. Liveness probes behave largely the same
as readiness probes, so much of the code is shared by introducing a
probeType paramater to distinguish the type when it matters. The
circular dependency between the runtime and the prober is broken by
exposing a shared liveness ResultsManager, owned by the
kubelet. Finally, an Updates channel is introduced to the ResultsManager
so the kubelet can react to unhealthy containers immediately.

kubelet: fix all sources ready condition

The current implementation considers a source seen when it receives a SET at
kubelet/config/config.go. However, the main kubelet sync loop may not have
received the pod update from the source via the channel. This change ensures
that kubelet would consider all sources are ready only after the sync loop has
seen all the sources.

Add NotReadyAddresses to Endpoints
...
In many cases clients may wish to view not ready addresses for endpoints
in order to do set membership prior to a pod being ready. For instance,
a pod that uses the service endpoints to connect to other pods under
the same service, but does not want to signal ready before it has
contacted at least a minimal number of other pods.
This is backwards compatible with old servers and clients. There is
an additional cost in size of endpoints before services ramp up, which
will add minor CPU and memory use for services that have a significant
number of pods which have not become ready.

Both GetNode and the cache.ListWatch listfunc in the

GetNodeInfo is sufficient for GetNode and makes looping

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.

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).

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.

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.

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.

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.

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.

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.

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).

Adapt pod killing and cleanup for generic container runtime
...
This change removes docker-specifc code in killUnwantedPods. It
also instructs the cleanup code to move away from interacting with
containers directly. They should always deal with the pod-level
abstraction if at all possible.

Fixed kubelet deleting data from volumes on stop ( #7317 ).
...
We must not clear the pod directory in killUnwantedPods(), volumes are still
mounted there at this time. There already is cleanupOrphanedPodDirs(),
called later in the SyncPods() sequence, which should remove these pod
directories.

2015-04-28 09:25:12 -07:00
6b0db76e85
Move killPod() logic to DockerManager KillPod().
...
This moved Docker specific logic there and allows it to align with the
runtime API. There is still a pod infra container reference in the
function due to network plugins. We can handle this in the Kubelet since
we'll need to be explicit in stating that the network plugin will not
work in a non-Docker runtime.

kubelet: filter out terminated pods in SyncPods
...
Once a pod reaches a terminated state (whether failed or succeeded), it should
not transit out ever again. Currently, kubelet relies on examining the dead
containers to verify that the container has already been run. This is fine
in most cases, but if the dead containers were garbage collected, kubelet may
falsely concluded that the pod has never been run. It would then try to restart
all the containers.
This change eliminates most of such possibilities by pre-filtering out the pods
in the final states before sending updates to per-pod workers.

Kubelet: parallelize cleaning up containers in unwanted pods

Kubelet kills unwanted pods in SyncPods, which directly impact the latency of a
sync iteration. This change parallelizes the cleanup to lessen the effect.
Eventually, we should leverage per-pod workers for cleanup, with the exception
of truly orphaned pods.
