Tests should never directly add to the global command line, because some users of the tests might not want them there. For example, options might only get set directly from a config file. To achieve that, e2e/framework/config, e2e/framework/viperconfig, and e2e/framework/test_context.go avoid using the global flag set and instead expect to be told by the caller which flag set to use. Tests that called flag directly either get updated or obsolete flags get removed. The exception is framework.HandleFlags, which as before directly implements global command line handling. This is a breaking change for test suites which do not use that function (and only those): they now need to ensure that they copy individual flags from tests. Because the RegisterCommonFlags prototype has changed, test suite authors will notice due to the resulting compilation errors.
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.
