All of the tests used a localDetector that considered the pod IP range to be 10.0.0.0/24, but lots of the tests used pod IPs in 10.180.0.0/16 or 10.0.1.0/24, meaning the generated iptables rules were somewhat inconsistent. Fix this by expanding the localDetector's pod IP range to 10.0.0.0/8. (Changing the pod IPs to all be in 10.0.0.0/24 instead would be a much larger change since it would result in the SEP chain names changing.) Meanwhile, the different tests were also horribly inconsistent about what values they used for other IPs, and some of them even used the same IPs (or ports) for different things in the same test case. Fix these all up and create a consistent set of IP assignments: // Pod IPs: 10.0.0.0/8 // Service ClusterIPs: 172.30.0.0/16 // Node IPs: 192.168.0.0/24 // Local Node IP: 192.168.0.2 // Service ExternalIPs: 192.168.99.0/24 // LoadBalancer IPs: 1.2.3.4, 5.6.7.8, 9.10.11.12 // Non-cluster IPs: 203.0.113.0/24 // LB Source Range: 203.0.113.0/25
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.

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.
