If you pass just an IP address to "-s" or "-d", the iptables command will fill in the correct mask automatically. Originally, the proxier was just hardcoding "/32" for all of these, which was unnecessary but simple. But when IPv6 support was added, the code was made more complicated to deal with the fact that the "/32" needed to be "/128" in the IPv6 case, so it would parse the IPs to figure out which family they were, which in turn involved adding some checks in case the parsing fails (even though that "can't happen" and the old code didn't check for invalid IPs, even though that would break the iptables-restore if there had been any). Anyway, all of that is unnecessary because we can just pass the IP strings to iptables directly rather than parsing and unparsing them first. (The diff to proxier_test.go is just deleting "/32" everywhere.) |

Kubernetes (K8s)
Kubernetes, also known as K8s, 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 K8s
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 K8s
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.
