This patch fixes a regression introduced by https://github.com/kubernetes/kubernetes/pull/51751 in the CRI interface. That commit actually changed a unit test where we were previously *not* assuming anything about an image name. Before that commit, if you send the image "busybox" through the CRI, the container runtime receives "busybox". After that patch the container runtime gets "docker.io/library/busybox". While that may be correct for the internal kube dockershim, in the CRI we must not assume anything about image names. The ImageSpec is not providing any spec around the image so the container runtime should just get the raw image name from the pod spec. Every container runtime can handle image names the way it wants. The "docker.io" namespace is not at all "standard", CRI-O is not following what the docker UI say since that's the docker UI. We should not focus the CRI on wrong UI design, especially around a default namespace. ImageSpec is not standardized yet: https://github.com/kubernetes/kubernetes/issues/46255 and https://github.com/kubernetes/kubernetes/issues/7203 This is something which should land in 1.9 as well since the regression is from 1.8.

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing 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 you are a company that 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 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.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/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.
