Kubernetes Submit Queue 45d122dd6b Merge pull request #36033 from DirectXMan12/feature/hpa-v2 
Automatic merge from submit-queue (batch tested with PRs 40796, 40878, 36033, 40838, 41210)

HPA v2 (API Changes)

**Release note**:
```release-note
Introduces an new alpha version of the Horizontal Pod Autoscaler including expanded support for specifying metrics.
```

Implements the API changes for kubernetes/features#117.

This implements #34754, which is the new design for the Horizontal Pod Autoscaler.  It includes improved support for custom metrics (and/or arbitrary metrics) as well as expanded support for resource metrics.  The new HPA object is introduces in the API group "autoscaling/v1alpha1".

Note that the improved custom metric support currently is limited to per pod metrics from Heapster -- attempting to use the new "object metrics" will simply result in an error.  This will change once #34586 is merged and implemented.

Cluster Federation

Kubernetes Cluster Federation enables users to federate multiple Kubernetes clusters. Please see the user guide and the admin guide for more details about setting up and using the Cluster Federation.

Building Kubernetes Cluster Federation

Please see the Kubernetes Development Guide for initial setup. Once you have the development environment setup as explained in that guide, you also need to install jq

Building cluster federation artifacts should be as simple as running:

make build

You can specify the docker registry to tag the image using the KUBE_REGISTRY environment variable. Please make sure that you use the same value in all the subsequent commands.

To push the built docker images to the registry, run:

make push

To initialize the deployment run:

(This pulls the installer images)

make init

To deploy the clusters and install the federation components, edit the ${KUBE_ROOT}/_output/federation/config.json file to describe your clusters and run:

make deploy

To turn down the federation components and tear down the clusters run:

make destroy

Ideas for improvement

  1. Continue with destroy phase even in the face of errors.

    The bash script sets set -e errexit which causes the script to exit at the very first error. This should be the default mode for deploying components but not for destroying/cleanup.
