It is useful to apply the storage testsuite also to "external" (= out-of-tree) storage drivers. One way of doing that is setting up a custom E2E test suite, but that's still quite a bit of work. An easier alternative is to parameterize the Kubernetes e2e.test binary at runtime so that it instantiates the testsuite for one or more drivers. Some parameters have to be provided before starting the test because they define configuration and capabilities of the driver and its storage backend that cannot be discovered at runtime. This is done by populating the DriverDefinition with the content of the file that the new -storage.testdriver parameters points to. The universal .yaml and .json decoder from Kubernetes is used. It's flexible, but has some downsides: - currently ignores unknown fields (see https://github.com/kubernetes/kubernetes/pull/71589) - poor error messages when fields have the wrong type Storage drivers have to be installed in the test cluster before starting e2e.test. Only tests involving dynamically provisioned volumes are currently supported. |

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.
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.
