Automatic merge from submit-queue kubectl: fall back to computing QoS class if server does not populate Fixes https://github.com/kubernetes/kubernetes/issues/42831 https://github.com/kubernetes/kubernetes/pull/38989 changed how kubectl determines the the QoS Class field. In order to prevent reimplementation of the QoS class logic in each client, the API server was modified to set the QoS Class in a new status field. However API servers 1.5 and older do not set this field. This results in a kubectl 1.6 client talking to a 1.5 API server to not print the QoS class field, which is a regression. This PR causes kubectl to fall back to the old method of evaluting the QoS class when the status field from the API server is not set. @vishh @derekwaynecarr @ymqytw @pwittrock @skriss |

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
If you are less impatient, 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.
