CreateDriver (now called SetupTest) is a potentially expensive operation, depending on the driver. Creating and tearing down a framework instance also takes time (measured at 6 seconds on a fast machine) and produces quite a bit of log output. Both can be avoided for tests that skip based on static information (like for instance the current OS, vendor, driver and test pattern) by making the test suite responsible for creating framework and driver. The lifecycle of the TestConfig instance was confusing because it was stored inside the DriverInfo, a struct which conceptually is static, while the TestConfig is dynamic. It is cleaner to separate the two, even if that means that an additional pointer must be passed into some functions. Now CreateDriver is responsible for initializing the PerTestConfig that is to be used by the test. To make this approach simpler to implement (= less functions which need the pointer) and the tests easier to read, the entire setup and test definition is now contained in a single function. This is how it is normally done in Ginkgo. This is easier to read because one can see at a glance where variables are set, instead of having to trace values though two additional structs (TestResource and TestInput). Because we are changing the API already, also other changes are made: - some function prototypes get simplified - the naming of functions is changed to match their purpose (tests aren't executed by the test suite, they only get defined for later execution) - unused methods get removed (TestSuite.skipUnsupportedTest is redundant)
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.
