Automatic merge from submit-queue (batch tested with PRs 46201, 45952, 45427, 46247, 46062) kubectl: fix deprecation warning bug **What this PR does / why we need it**: Some kubectl commands were deprecated but would fail to print the correct warning message when a flag was given before the command name. # Correctly prints the warning that "resize" is deprecated and # "scale" is now preferred. kubectl resize [...] # Should print the same warning but no warning is printed. kubectl --v=1 resize [...] This was due to a fragile check on os.Args[1]. This commit implements a new function deprecatedCmd() that is used to construct new "passthrough" commands which are marked as deprecated and hidden. Note that there is an existing "filters" system that may be preferable to the system created in this commit. I'm not sure why the "filters" array was not used for all deprecated commands in the first place. **Release note**: ```release-note NONE ```
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.
