Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- mounttest
- mounttest-user
Additionally, removes the usage of the mounttest-user image and removes
it from kubernetes/test/images. RunAsUser is set instead of having that image.
The image "gcr.io/authenticated-image-pulling/windows-nanoserver:v1" is not a
manifest list, and it is only useful for Windows Server 1809, which means that the
test "should be able to pull from private registry with secret" will fail for
environments with Windows Server 1903, 1909, or any other future version we might
want to test.
This commit adds the the ability to have an alternative private image to pull by
using a configurable docker config file which contains the necessary credentials
needed to pull the image.
Similar functionality is required across e2e tests for RuntimeClass.
Let's create runtimeclass as part of the framework/node package.

All tests remove the test client pod, usually in TestVolumeClient.
Rename TestCleanup to TestServerCleanup.
In addition, remove few calls to Test(Server)Cleanup that do not do anything
useful (server pod is not used in these tests).
The kubelet test here is using a one minute timeout, instead of the
normal framework.PodStartTimeout.
The DNS results validation functions pull several images including
the jessie-dnsutils which is a bit bigger than usual.
As of https://github.com/kubernetes/kubernetes/pull/72831, the minimum
docker version is 1.13.1. (and the minimum API version is 1.26). The
only time the `RuntimeAdmitHandler` returns anything other than accept
is when the Docker API version < 1.24. In other words, we can be
confident that Docker will always support sysctl.
As a result, we can delete this unnecessary and docker-specific code.
Some tests are setting HostNetwork=true, even if it is not required
for them to pass.
This patch will set the HostNetwork to false for those tests, allowing
them to be run on Windows nodes as well.
We've added the WindowsRunAsUserName feature some time ago, and it was
promoted to Beta for v1.17. We can now remove the [LinuxOnly] tag for
a few tests.

This is the last PR which moves functions from e2e/framework/util.go
- WaitForServiceWithSelector: Moved to e2e/cloud/gcp
- WaitForStatefulSetReplicasReady: Moved to e2e/storage
- WaitForRCToStabilize: Moved to e2e/kubectl
- CheckInvariants: Moved to e2e/common
- ContainerInitInvariant: Moved to e2e/common
- DumpEventsInNamespace: Renamed to local function
- WaitForDaemonSets: Moved to e2e/e2e.go
The redis version has been bumped to version 5.0.5, but the maximum version supported on
Windows is 3.2. This can lead to failing tests, the output and behaviour can be different
(see #80516). In order to prevent such failures, the amount of times the Redis image is
used can be reduced.
This commit uses the previously added agnhost guestbook subcommand as a replacement for the
Guestbook application created by the test "should create and stop a working application".
Adds AgnhostPrivate to test/utils/image/manifest. Some tests are trying to pull
the agnhost image from the private registry, meaning that we would need to
always build and push the agnhost image to both e2e and private registry
whenever we bump its version. Decoupling them would mean that we only need
to push the image to the e2e registry.
Use POST method instead of running local kubectl.
Use ExecCommandInContainerWithFullOutput() instead of RunKubectl().
PodExec() takes additional framework arg, passed down in call chain.
VerifyExecInPodFail uses different error code cast as original
one causes test code Panic if used with new call method.
Since we've added support for RunAsUserName, we can now run some new
tests. However, the [LinuxOnly] tag will have to remain until the
WindowsRunAsUserName feature becomes enabled by default.
Additionally, Containerd supports file mounting on Windows, and some
tests will be able to pass on Windows with Containerd instead of Docker.
Melds the "pull image from gcr.io" and "pull image from docker hub" tests
into a single test that pulls the agnhost image from the configured
e2eRegistry.
This also removes the need to maintain and update the image
"gcr.io/kubernetes-e2e-test-images/windows-nanoserver:v1". It should have been
a manifest list that also includes future Windows releases, like Windows Server 1903.
Additionally, the image has ~300 MB, meaning that with this change, it won't have to
wait as much to spawn a pod.
Removes "should not be able to pull non-existing image from gcr.io", since
the test "should not be able to pull image from invalid registry" test already
exists, and both of them test the same effect: cannot spawn a pod with an
image that does not exist.
Moving pod related functions from e2e/framework/pv_util.go to

Skips IPv6 tests on Windows.
Skips sysctl tests on Windows.
Skips network policy tests on Windows.
Skips RunAsUser / FSGroup / file permissions related tests, as those are
not supported on Windows.
Skips the test "should preserve source pod IP for traffic thru service cluster IP"
on Windows, as it creates a Pod with HostNetwork=true, which is unsupported.
What works and what doesn't work on Windows has been documented here:

RunDeployment() of the deployment e2e framework was used in
autoscaling_utils only. In addition, the deployment e2e framework
imported the core of e2e framework only for the function.
So this moves the function into autoscaling_utils then we can remove
dependency of core framework from the deployment e2e framework.
In ObserveEventAfterAction(), observedMatchingEvent is set if ok is
true. Now the ok is already checked with framework.ExpectEqual().
So this removes duplicated check for code cleanup.

This PR replaces the usage of the following images with agnhost:

- porter
- serve-hostname
As https://github.com/kubernetes/kubernetes/pull/78478 we can use
ExpectNoError() instead of Expect(err).ToNot(HaveOccurred()) also.
This makes the test code check strict to cover the above case and
replaces the remaining in test/e2e/common/expansion.go
- Add a package "node" under e2e/framework and alias e2enode;
- Rename some functions whose name have redundant string.

Because Linux images cannot run on Windows and vice-versa, separate
tests were added for both OSes, only separated by a [LinuxOnly] tag
in their names.
Based on the given --node-os-distro, we can select which image to
use when spawning the pod.

This is part of the transition to using framework/log instead
of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
This is the continuation of the refactoring of framework/deployment_utils.go
into framework/deployment.

Basically conformance test checks the target k8s cluster works all
features which are specified in each test and that should not depend
on any condition.
This adds checking that conformance test should not call any Skip
methods. And it detects the existing conformance test
"creating/deleting custom resource definition objects works"
calls framework.SkipUnlessServerVersionGTE(). So this removes the
Skip also.
Previous IPv6 regex was too loose, this patchs adds a better and

regex availables as constants inside the framework pkg
