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.
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.
The `err` return value was being overwritten in an unintended way, which
means the function may not return the proper error value. This diff
ensures it does.
A number of tests were using hardcoded image paths instead of
going through the imageutils package. The reason for centralizing
the logic there is to keep an eye on what images we use and where
they come from.
There is strong probabilty that some pods will be deleted when
we are bombarding cluster with high volume of pods. We do that in
Cluster Autoscaler scalability tests and we want to relax check there.

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:
- audit-proxy
- crd-conversion-webhook
- entrypoint-tester
- inclusterclient
- iperf
- porter
- serve-hostname
