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. |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts. It provides basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If your company wants to help shape the evolution of technologies that are container-packaged, dynamically scheduled, and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To use Kubernetes code as a library in other applications, see the list of published components.
Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make
You have a working Docker environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
