Anthony Yeh e2deb1795d DaemonSet: Mark daemonset-lookup-cache-size flag as deprecated. 2017-03-07 16:42:29 -08:00
Anthony Yeh 1099811833 DaemonSet: Use ControllerRef to route watch events.

Anthony Yeh ca13b9e532 RC/RS: Use ControllerRef to route watch events. 
This is part of the completion of ControllerRef, as described here:

https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md#watches

This also removes the need for the Pod->Controller mapping cache in RC
and RS. This mapping is now persisted in the Pod's ControllerRef
instead.

Solly Ross d6fe1e8764 HPA Controller: Use Custom Metrics API 
This commit switches over the HPA controller to use the custom metrics
API.  It also converts the HPA controller to use the generated client
in k8s.io/metrics for the resource metrics API.

In order to enable support, you must enable
`--horizontal-pod-autoscaler-use-rest-clients` on the
controller-manager, which will switch the HPA controller's MetricsClient
implementation over to use the standard rest clients for both custom
metrics and resource metrics.  This requires that at the least resource
metrics API is registered with kube-aggregator, and that the controller
manager is pointed at kube-aggregator.  For this to work, Heapster
must be serving the new-style API server (`--api-server=true`).

Jing Xu 7604163560 Change default reconciler sync period to 1 minute 
When default reconciler sync period is set to 5 second, we often see
rateLimit issue for a large cluster. This PR is change the period to 1
minute to mitigate this problem.

Make this period longer means that there might be some period of time
that the cached information in master's attach_detach_controller is out
of date. The node might use this information to mount to the wrong
device. For GCE PD, since device path is uniquely associated with volume
id, so mount operation will just fail because of this outdated
information. For AWS, before kubelet might mount to the wrong volume
because device path could be reused immediately once it is available.
But after PR #38818, device path will only be reused after all device
paths have been explored. That means it is very unlikely that kubelet will
mount to a wrong volume that is using the old device path that had been
assigned to the same node.

Enable the garbage collector by default

Turning GC on by default.

Memory usage of GC is back to normal after #30943. The CPU usage is a little higher than the cap in scalability test (1.11 core vs. 1 core). This PR adjusted the default GC worker to 20 to see if that helps CPU usage.

Justin Santa Barbara b754393630 kube-controller-manager: Add configure-cloud-routes option 
This allows kube-controller-manager to allocate CIDRs to nodes (with
allocate-node-cidrs=true), but will not try to configure them on the
cloud provider, even if the cloud provider supports Routes.

The default is configure-cloud-routes=true, and it will only try to
configure routes if allocate-node-cidrs is also configured, so the
default behaviour is unchanged.

This is useful because on AWS the cloud provider configures routes by
setting up VPC routing table entries, but there is a limit of 50
entries.  So setting configure-cloud-routes on AWS would allow us to
continue to allocate node CIDRs as today, but replace the VPC
route-table mechanism with something not limited to 50 nodes.

We can't just turn off the cloud-provider entirely because it also
controls other things - node discovery, load balancer creation etc.
