The build times are a bit high for the image builder (~50 minutes), and it will a bit more
when Windows support will be added to the other test images. This commit changes the
machineType to N1_HIGHCPU_8.
Reenables Windows test image building. Added DOCKER_CERT_BASE_PATH (default value: $HOME),
which will contain the path where the certificates needed for Remote Docker Connection can
be found.
If a REMOTE_DOCKER_URL was not set for a particular OS version, exclude that image from the
manifest list. This fixes an issue where, if REMOTE_DOCKER_URL was not set for Windows Server 1909,
the Windows were completely excluded from the manifest list, including for Windows Server 1809
and 1903 which could have been built and pushed.
Sets "test-webserver" as the default CMD for kitten and nautilus. Since they are now based on
agnhost, they should be set to run test-webserver to maintain previous behaviour.
Bumps the agnhost version to 2.13, as 2.12 has already been promoted. 2.13 will contain
Windows support.
Adds Windows support for the kitten and nautilus images, so they can promoted together
with agnhost (they were not previously promoted).
Adds OWNERS files to: agnhost, busybox, kitten, nautilus.
The current agnhost version is 2.12, 2.11 was not previously built as the
VERSION bumps merged one after the other, and the Image Promoter did not get to
build the 2.11 image.
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.
Changes the image naming template from:
$REGISTRY/$image-$arch:$TAG
to
$REGISTRY/$image:$TAG-$os_name-$arch
The previous naming template would generate a plethora of images (Ai * N images,
where Ai is the number of OS/architectures for the image i and N is the number
of images), while the new naming template will reduce the number of images to N.
The new template also includes the OS name, as we plan to integrate Windows
images into the manifest lists as well.
When building images, their REGISTRY can be set to a custom
one, instead of the default "gcr.io/kubernetes-e2e-test-images" or
"us.gcr.io/k8s-artifacts-prod/e2e-test-images".
Some images are based on other images we're already building
(e.g.: kitten, nautilus), but their base images
are set in the default registry name, which can be undesirable.
This commit addresses this issue.
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.
Centralizes the following images into agnhost:
- dnsutils
- mounttest
- resource-consumer-controller
- test-webserver
Adds CoreDNS to agnhost image, which can be used in some DNS related tests (dnsmasq is Linux-only).
Adds Windows support to mounttest.
Bumps agnhost version to 2.9.
Bumps kitten version to 1.1.
Bumps nautilus version to 1.1.
