Some of these tests could not be run previously, especially on Windows
Docker containers. But now, by using Windows Containerd, we can finally
run them:
- HostNetwork=true tests: This can now be enabled on Windows Privileged Containers.
- /etc/hosts related tests: These were not supported because it required single
file mappings, which is possible in Containerd.
- termination message as non-root user: Requires RunAsUsername, and single file
mappings.
This test has been part of the Conformance suite since at least
Kubernetes 1.2 (2015-10-xx). Some years later, around 2018-10-xx, we
drafted a rigorous set of rules for tests to follow in order to be
eligible for promotion to Conformance. We explicitly disallowed any
tests that check for specific Events, since they are not an API, and we
make no guarantees about their contents nor their delivery.
Unfortunately, we neglected to go through the existing corpus of
Conformance tests with a fine-toothed comb after drafting these rules.
The very nature of what this test is attempting to exercise and verify
is specific Events, and their delivery, thus making it ineligible for
Conformance. We should have caught and demoted this test back then.
Better late than never?
The e2e test "should have Endpoints and EndpointSlices pointing to
the API Server Service" was veryfing the current endpoints
reconciler implementation on the apiservers, however, users may
disable the endpoint reconciler and create their own.
This e2e test is also a conformance test, so we should test the
behaviour and not the implementation details. The test verifies
that a kubernetes.default service exist, an endpoint and endpoint
slices object referencing that service exist and are equivalent.
Windows Containerd has more features than Windows Docker. One of them is single file
mappings, allowing us to also map individual files into containers, not just folders.
This will set the tag [Excluded:WindowsDocker] for those tests instead of [LinuxOnly].

In the case of multinode clusters, the http server pod and the test cluster can
spawn on different nodes, which can be problematic for poststart / prestop hooks,
as they are executed by the kubelet itself, and the cross-node lifecycle hook might
fail (according to the Kubernetes network model, it is not mandatory for kubelet to
be able to access pods on a different node).
This commit ensures that the test pod spawns on the same node as the http server pod.
