Unfortunately, the NUMA information is not readily available from
cadvisor, so we have to roll the logic to discover it by hand. In the
future, we should remove this custiom code to use the information
provided by cadvisor once it is made available.
At present, there is no way for a hint provider to return distinct hints
for different resource types via a call to GetTopologyHints(). This
means that hint providers that govern multiple resource types (e.g. the
devicemanager) must do some sort of "pre-merge" on the hints it
generates for each resource type before passing them back to the
TopologyManager.
This patch changes the GetTopologyHints() interface to allow a hint
provider to pass back raw hints for each resource type, and allow the
TopologyManager to merge them using a single unified strategy.
This change also allows the TopologyManager to recognize which
resource type a set of hints originated from, should this information
become useful in the future.
Previously, the cpumanager would simply fall back to the None() policy
if an invalid policy was specified. This patch updates this to return an
error when an invalid policy is passed, forcing the kubelet to fail
fast when this occurs.
These semantics should be preferable because an invalid policy likely
indicates operator error in setting the policy flag on the kubelet
correctly (e.g. misspelling 'static' as 'statiic'). In this case it is
better to fail fast so the operator can detect this and correct the
mistake, than to mask the error and essentially disable the cpumanager
unexpectedly.
The cpumanager loops through all init Containers and app Containers when
reconciling its state. However, the current implementation of
findContainerIDByName(), which is call by the reconciler, does not
resolve for init Containers.
This patch updates findContainerIDByName() to account for init
Containers and adds a regression test that fails before the change and
succeeds after.
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

This also incorporates the version string into the package name so
that incompatibile versions will fail to connect.
Arbitrary choices:
- The proto3 package name is runtime.v1alpha2. The proto compiler
normally translates this to a go package of "runtime_v1alpha2", but
I renamed it to "v1alpha2" for consistency with existing packages.
- kubelet/apis/cri is used as "internalapi". I left it alone and put the
public "runtimeapi" in kubelet/apis/cri/runtime.
