Automatic merge from submit-queue

Reduce hollow proxy mem/node

As likely expected, kubemark-scale failed to even start with n1-standard-8 nodes. Because 1/3rd of our hollow nodes didn't even get scheduled due to their requests:

```
I0720 17:45:08.139] Found only 3325 ready hollow-nodes while waiting for 5000.
I0720 17:45:20.435] 3326 hollow-nodes are reported as 'Running'
I0720 17:45:20.442] 1675 hollow-nodes are reported as NOT 'Running'
```

If we want to experiment with smaller nodes anyway, then this change is needed. Though we most likely will end up OOM'ing.

Explanation for new value:
We have 62.5 hollow-node / real-node
=> mem available per hollow node = 30GB / 62.5 = 480MB
minus 100MB (kubelet)
minus 20MB (npd) 
=> 360MB for proxy should be = 100MB + 5000*(mem/node)
=> 50KB mem/node (with some slight slack)

Kubernetes

Submit Queue Widget GoDoc Widget


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.
