Adds reviewers to the OWNERS files in the kubernetes/test/images folder.
The reviewers are added automatically, based on their contributions on
an image (>= 20% code churn).
Note that the code churn is taken into account for authors, and not committers.
Adds OWNERS files for: cuda-vector-add, nonewprivs, pets, redis, volume.
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.
