The Container Images for Windows Server 2022 have been published, and
we can start building test images using them, so we can start adding
jobs for them.
The image versions for the e2e test images have been bumped in a previous
commit, but haven't been promoted yet. We don't need to bump them here.
httpd-2.4.46-win64-VC15.zip no longer exists, so we have to use
httpd-2.4.48-win64-VC15.zip instead.
We've added Windows support to the resource-consumer image and 1.8 tag is already promoted.
We need to bump the VERSION, so we can promote the new image.
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.
Many README files and other docs contained a link to a an appspot
tracking app that is no longer active. Following the links leads to an
error about Go 1.9 no longer being supported. Go 1.9 support was dropped
in appspot in 2019 and disabled June 2020.
This also resulted in a broken image link displaying when viewing these
files on GitHub. Since the app is no longer functioning, and since it
causes a potentially (but granted, minor) confusing error to display,
this just removes those links as I don't believe they are needed
anymore.

Adds Windows support to the test/images/image-util.sh script.
A Windows node with Docker installed is required to build Windows images.
The connection URL to it must be set in the REMOTE_DOCKER_URL env variable.
Additionally, the authentication to the remote docker node is done through
certificates, which must be found in ~/.docker.
By default, the REMOTE_DOCKER_URL env variable is set to "" in the Makefile,
and because of it, the image-util.sh script will skip building and pushing
Windows images.
Added GOOS argument to the go build process in order to be able to build
Windows binaries. Additionally, the OS env variable was added to the images
Makefiles (default value is "linux") in order to maintain default behaviour.
Some images require a different Dockerfile for Windows images, since they
have different ways of installing dependencies. Because of this, if a image
needs to be built for Windows, it will first check for a Dockerfile_windows
file instead of the default one. If there isn't one, it means that the
same Dockerfile can be used for both Windows and Linux.
All Windows images will be based on the image
"mcr.microsoft.com/windows/servercore:ltsc2019". There are a couple of features
that are needed from this image, especially powershell.
Added busybox image for Windows. Most Windows images will be based on it, which
will help reduce the command line differences between Linux and Windows, but
not entirely.
Added Windows support for agnhost image.
Windows images will require other base images, and thus, we will need
to explicitly specify the OS type a base image is for in order to
avoid confusion or errors.
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.
In order to build the image binaries, the GOARM variable is required,
but not all Makefiles have it defined, causing the make to fail on
those images.
This adds the require GOARM variable to the Makefiles in question.
Dockerhub does not support slashes in the image names, so when the tests are
configured to use a dockerhub registry instead of the current
gcr.io/kubernetes-e2e-test-images registry, the tests using the mentioned image
will fail, as the image cannot exist and cannot be pulled.
This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
