Automatic merge from submit-queue Block on master-creation step for large clusters (>50 nodes) in kube-up I recently noticed a failure in our 5000-node scale test where the master failed to initialize within time. But it went on and created all 5000 nodes due to not blocking on master creation. Turned out the master VM wasn't even created: ``` W0808 10:00:49.340] ERROR: (gcloud.compute.instances.create) Could not fetch resource: ... Try a different zone, or try again later. ``` Even some of our 100-node tests are flaking occasionally during cluster startup (with master validation step timing out) and I think the reason is the same (issue - https://github.com/kubernetes/kubernetes/issues/49453) We should block on that step for large clusters. cc @kubernetes/sig-scalability-misc @gmarek |

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.
