Automatic merge from submit-queue (batch tested with PRs 64272, 64630). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. GCE: Fix operation polling and error handling Cloud functions using the generated API are bursting operation GET calls because we don't wait a minimum amount of time. Fixes #64712 Fixes #64858 **Changes** - `operationPollInterval` is now 1.5 seconds instead of 3 seconds. - `operationPollRateLimiter` is now configured with 5 QPS / 5 burst instead of 10 QPS / 10 burst. - `gceRateLimiter` is now configured with a `MinimumRateLimiter` to wait the above `operationPollInterval` duration _before_ waiting on the token rate limiter. - Operations are now rate limited on the very first GET call. - Operations are polled until `DONE` or context times out (even if operations.get fails continuously). - Compute operations are checked for errors when they're recognized as `DONE`. - All "wrapper" funcs now generate a context with an hour timeout. `ingress-gce` will need to update its vendor and utilize the `MinimumRateLimiter` as well. Since ingress creates rate limiters based off flags, we'll need to check the resource type and operation while parsing the flags and wrap the appropriate one. **Special notes for your reviewer**: /assign bowei /cc bowei **Fix Example** Creating an external load balancer without fix: https://pastebin.com/raw/NNkeNWS3 with fix: https://pastebin.com/raw/x2iMLW5S (a difference of about 200 GET calls) **Release note**: ```release-note GCE: Fixes operation polling to adhere to the specified interval. Furthermore, operation errors are now returned instead of ignored. ``` |

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.
