current scale. Two important ones are when missing metrics might change the direction of scaling, and when the recommended scale is within tolerance of the current scale. The way that ReplicaCalculator signals it's desire to not change the current scale is by returning the current scale. However the current scale is from scale.Status.Replicas and can be larger than scale.Spec.Replicas (e.g. during Deployment rollout with configured surge). This causes a positive feedback loop because scale.Status.Replicas is written back into scale.Spec.Replicas, further increasing the current scale. This PR fixes the feedback loop by plumbing the replica count from spec through horizontal.go and replica_calculator.go so the calculator can punt with the right value. |

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.
