Some of these images didn't have any job run for them. Some of these
images previously failed due to an issue that has been addressed since.
Making a change into their image directory will spawn a postsubmit job
that will build that image.
The way the images are built is going to be changed, and in order to avoid
overwritting and breaking the current images, the image versions are bumped.
Prior to the Image Centralization part 4 (https://github.com/kubernetes/kubernetes/pull/81170),
a PR merged that enables the Image Promoter to run on the k/k test images.
The Image Promoter currently only builds the Conformance-related images, but the
Image Centralization part 4 centralized some of those images into agnhost, so they
need to be removed from the conformance_images list.
Additionally, https://github.com/kubernetes/kubernetes/pull/81226 proposes mounttest-user
image to be removed, and RunAsUser to be used in tests instead.
The image used by the Image Promoter (gcr.io/k8s-testimages/gcb-docker-gcloud:v20190906-745fed4)
is based on busybox, and thus, the sed binary is actually busybox. image-util.sh calls
kube::util::ensure-gnu-sed several times, which ensures that a GNU sed binary exists
(it checks by greping GNU in its --help output). Obviously, it won't match the busybox sed
binary. But the sed usage in image-util.sh is fairly simple, and the busybox sed is sufficient.
Bumps image versions for: jessie-dnsutils, nonewprivs, resource-consumer, sample-apiserver. These
images are included in the conformance_images that are being built by the Image Promoter, so
we're bumping them just to make sure we're not breaking anything and cause all the CIs to fall.
We're going to bump the image versions used in tests in a subsequent PR. The image version was not
bumped for: agnhost, kitten, nautilus, as they were already bumped by the Image Centralization part 4
PR.
The dnsutils and jessie-dnsutils images are installing dnsmasq,
which is required for a few tests checking custom DNS servers and
configurations.
dnsmasq is a Linux specific binary. In order for the tests to also
pass on Windows, this commit adds CoreDNS to the images, so a later
commit will update the tests to use CoreDNS instead of dnsmasq.
