Not every object kind can be registered via tracker .Add() called as part of SimpleClientset initialization. This is because .Add() relies on UnsafeGuessKindToResource to convert object kinds into resource type names, which is broken for some resources. An example of an affected kind is NetworkAttachmentDefinitions CRD that uses network-attachment-definitions as its resource type name. When UnsafeGuessKindToResource is called for this kind, it returns networkattachmentdefinitions (without dashes). As per the comment inside .Add, kinds affected by UnsafeGuessKindToResource deficiencies should instead register objects using tracker .Create() method. Problem is, current SimpleClientset struct definition doesn't expose the object tracker in any way, which makes it impossible to properly register these kinds at all. To address the issue, this change modifies the definition of SimpleClientset struct to expose the object tracker used via Tracker() method.
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.
