Windows Kernel now exposes "Internal Load Balancing" using VFP (Virtual Filtering Platform) part of Virtual Switch. An inbuild windows service HNS (Host Networking Service) acts as interface to program the VFP. VFP is synonymous to iptables in functionality. HNS uses json based data as input. With the help of the interface available in github.com/Microsoft/hcsshim, these APIs are exposed to the world in github to program HNS and use the feature. *** More info about the changes in this PR *** (1) For every endpoint available in the system, an HNS Endpoint is added (1.a) for local endpoints, a local HNS Endpoint would already exist, as part of container creation. (1.b) For all remote endpoints, a remote HNS Endpoint is created via HNS (2) For every Service, a HNS ILB LoadBalancer is added referring the endpoints created in (1) Sample Input to HNS: { "Policies": [ { "ExternalPort": 80, "InternalPort": 80, "Protocol": 6, "Type": "ELB", "VIPs": [ "11.0.98.129" ] } ], "References": [ "/endpoints/ca8b877b-ab90-499a-bc0e-7d736c425632", "/endpoints/ee0ef08b-8434-4f8b-b748-393884e77465" ] } (2-a) This is done for Cluster IP, LoadBalancer Ingress IP, NodePort, External IP Following the regular service and endpoint updates, the HNS is notified of the updates and the system is kept in sync. |

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
If you are less impatient, 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.
