Automatic merge from submit-queue (batch tested with PRs 66410, 66398, 66061, 66397, 65558). 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>. Fix volume limit for EBS on m5 and c5 instances This is a fix for lower volume limits on m5 and c5 instance types while we wait for https://github.com/kubernetes/features/issues/554 to land GA. This problem became urgent because many of our users are trying to migrate to those instance types in light of spectre/meltdown vulnerability but lower volume limit on those instance types often causes cluster instability. Yes they can workaround by configuring the scheduler with lower limit but often this becomes somewhat difficult to do when cluster is mixed. The newer default limits were picked from https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html Text about spectre/meltdown is available on - https://community.bitnami.com/t/spectre-variant-2/54961/5 /sig storage /sig scheduling ```release-note Fix volume limit for EBS on m5 and c5 instance types ``` |

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.
