The test "should write entries to /etc/hosts" should have the [LinuxOnly] tag as
it cannot pass on Windows; individual files cannot be mounted in Windows Containers.
This test was missed in the original PR (https://github.com/kubernetes/kubernetes/pull/73204)
Adds the test "should be able to pull image from docker hub [WindowsOnly]",
which will pull a Windows busybox image from dockerhub. Since it is busybox,
the same command will also work for this image.
The busybox image is currently used in other E2E tests, so the image should
already be prepulled on the nodes. Additionally, the image has a manifest list
for Windows Server 1803 and Windows Server 2019, and future versions will be
added to it.
Some of the tests cannot pass using Windows nodes due to various reasons:
- seLinuxOptions are not supported on Windows.
- Running as an UID / GID is not supported on Windows.
- file permissions work differently on Windows, and they cannot be set in
the same manner as on Linux.
- individual files cannot be mounted in Windows Containers.
- Cannot create container using Linux image (e.g.: alpine) on Windows.
Because of this, it has been decided to use the "[LinuxOnly]" tag for the
tests which cannot run on Windows because of the mentioned reasons. This way,
when running tests using Windows nodes, those tests can simply be skipped by
adding the "[LinuxOnly]" tag to the ginkgo.skip argument.
Some tests use .yaml files to deploy pods, which have hardcoded
images. Those images cannot be used for Windows containers.
The image names can be injected by the tests themselves, based on
the configured registries.
Remove SLOW tag and update description for KUBEDESCRIBE(Probing container) and SIGDESCRIBE(EmptyDir Wrapper Volume)
Remove slow references for tests that execute below 5 minutes
Some mounttest related tests are checking the file permissions set on the
container files, but the default file permissions on Windows is 775 instead of
644, causing some tests to fail.
Keep in mind that file permissions work differently on Windows, and setting file
permissions via Kubernetes is not currently supported on Windows.
- 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

When node lease feature is enabled, kubelet reports node status to api server
only if there is some change or it didn't report over last report interval.
As discussing on #68905
some tests of test/e2e/common/host_path.go are covered with
test/e2e/storage/testsuites/subpath.go
So we don't need to keep them in test/e2e/common/host_path.go
anymore for the maintenance.
- Scale down based on custom metric was flaking. Increase target value
of the metric.
- Scale down based on CPU was flaking during stabilization. Increase
tolerance of stabilization (caused by resource consumer using more CPU
than requested).
The test "should run with the expected status" passes with and without
the set SELinuxOptions, but removing it will ensure that the test will
be able to run and pass on Windows nodes as well.

Tests: Make e2e test platform-agnostic
The test:
[k8s.io] Pods should support remote command execution over websockets [NodeConformance]
uses cat on /etc/resolv.conf and checks if the output from the container is "namespace",
which is incompatible with windows containers as there is no such file.
Since the test just check if remote command execution works, the command is
irrelevant as long as the output checks out. Switched to using echo "remote execution test",
and checking that output as it works for both windows and linux.
This extends the Kubelet to create and periodically update leases in a
new kube-node-lease namespace. Based on [KEP-0009](https://github.com/kubernetes/community/blob/master/keps/sig-node/0009-node-heartbeat.md),
these leases can be used as a node health signal, and will allow us to
reduce the load caused by over-frequent node status reporting.
- add NodeLease feature gate
- add kube-node-lease system namespace for node leases
- add Kubelet option for lease duration
- add Kubelet-internal lease controller to create and update lease
- add e2e test for NodeLease feature
- modify node authorizer and node restriction admission controller
to allow Kubelets access to corresponding leases

An consolidated effort to resolve the issue https://github.com/kubernetes/kubernetes/issues/66875
> _[sig-storage] Secrets should be able to mount in a volume regardless of a different secret existing with same name in different namespace_
Promoting mentioned e2e test for Conformance as it -
- Validates that secret with same name can be created in different namespaces but secrets which reside in same namespace as that of pod can be only be accessed from volume mounted in the container.
- Improves api coverage including prioritized Pod API lists. https://github.com/cncf/k8s-conformance/issues/220#issuecomment-393344061

HPA: Make dynamicRequestSizeInMillicores bigger
**What this PR does / why we need it**:
HPA e2e tests specify 20 as requestSizeMillicores on resource-consumer
for making CPU workload to test HPA feature, and the value is
hard-coded as 20. That means the tests expect 2% CPU workload on every
resource-consumer process, but actual CPU usage(4 - 6%) is over than
the expected usage on some environment. Then HPA scales many pods than
the test expected, and the test is failed.
To make these tests stable, this changes the value to 100 (10% CPU
workload on each process).

Currently, the limit set in the tests is 30 MB, which will cause

Adding details to Conformance Tests using RFC 2119 standards.
This PR is part of the conformance documentation. This is to provide more formal specification using RFC 2119 keywords to describe the test so that who ever is running conformance tests do not have to go through the code to understand why and what is tested.
The documentation information added here into each of the tests eventually result into a document which is currently checked in at location https://github.com/cncf/k8s-conformance/blob/master/docs/KubeConformance-1.9.md
I would like to have this PR reviewed for v1.10 as I consider it important to strengthen the conformance documents.
