The main purpose of this change is to update the e2e Netpol tests to use the srandard CreateNamespace function from the Framework. Before this change, a custom Namespace creation function was used, with the following consequences: * Pod security admission settings had to be enforced locally (not using the centralized mechanism) * the custom function was brittle, not waiting for default Namespace ServiceAccount creation, causing tests to fail in some infrastructures * tests were not benefiting from standard framework capabilities: Namespace name generation, automatic Namespace deletion, etc. As part of this change, we also do the following: * clearly decouple responsibilities between the Model, which defines the K8s objects to be created, and the KubeManager, which has access to runtime information (actual Namespace names after their creation by the framework, Service IPs, etc.) * simplify / clean-up tests and remove as much unneeded logic / funtions as possible for easier long-term maintenance * remove the useFixedNamespaces compile-time constant switch, which aimed at re-using existing K8s resources across test cases. The reasons: a) it is currently broken as setting it to true causes most tests to panic on the master branch, b) it is not a good idea to have some switch like this which changes the behavior of the tests and is never exercised in CI, c) it cannot possibly work as different test cases have different Model requirements (e.g., the protocols list can differ) and hence different K8s resource requirements.

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.
Community Meetings
The Calendar has the list of all the meetings in Kubernetes community in a single location.
Adopters
The User Case Studies website has real-world use cases of organizations across industries that are deploying/migrating to Kubernetes.
Governance
Kubernetes project is governed by a framework of principles, values, policies and processes to help our community and constituents towards our shared goals.
The Kubernetes Community is the launching point for learning about how we organize ourselves.
The Kubernetes Steering community repo is used by the Kubernetes Steering Committee, which oversees governance of the Kubernetes project.
Roadmap
The Kubernetes Enhancements repo provides information about Kubernetes releases, as well as feature tracking and backlogs.
