IsListType was causing ~100 allocations for a non list object. It is used in a wide range of code, so perform a more targeted check. The use of `%#v` in a hot return path for `fmt.Errorf()` was the main victim. Replace `%#v` with a typed error and create a cache of types that are lists with a bounded size (probably not necessary, but safer). ``` BenchmarkGet-12 100000 119635 ns/op 20110 B/op 206 allocs/op BenchmarkWatchHTTP-12 100000 65761 ns/op 7296 B/op 139 allocs/op BenchmarkGet-12 100000 109085 ns/op 17831 B/op 152 allocs/op BenchmarkWatchHTTP-12 200000 33966 ns/op 1913 B/op 30 allocs/op ``` |

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.
