This patch fixes an issue in the TopologyManager that wouldn't allow pods to be admitted if pods were launched with the SingleNUMANode policy and any of the hint providers had no NUMA preferences. This is due to 2 factors: 1) Any hint provider that passes back a `nil` as its hints, has its hint automatically transformed into a single {11 true} hint before merging 2) We added a special casing for the SingleNumaNodePolicy() in the TopologyManager that essentially turns these hints into a {11 false} anytime a {11 true} is seen. The current patch reworks this logic so the that TopologyManager can tell the difference between a "don't care" hint and a true "{11 true}" hint returned by the hint provider. Only true "{11 true}" hints will be converted by the special casing for the SingleNumaNodePolicy(), while "don't care" hints will not. This is a short term fix for this issue until we do a larger refactoring of this code for the 1.17 release. |

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 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.
