This PR makes two changes. One is to introduce a parameter for the HTTP/2 setting that an api-server sends to its clients telling them how many streams they may have concurrently open in an HTTP/2 connection. If left at its default value of zero, this means to use the default in golang's HTTP/2 code (which is currently 250). The other change is to make the recommended options for an aggregated api-server set this limit to 1000. The limit of 250 is annoyingly low for the use case of many controllers watching objects of Kinds served by an aggregated api-server reached through the main api-server (in its mode as a proxy for the aggregated api-server, in which it uses a single HTTP/2 connection for all calls proxied to that aggregated api-server). Fixes #60042 Kubernetes-commit: 201c11f147c85b029665915bee3a62eea19d6d57 |

apiserver
Generic library for building a Kubernetes aggregated API server.
Purpose
This library contains code to create Kubernetes aggregation server complete with delegated authentication and authorization,
kubectl compatible discovery information, optional admission chain, and versioned types. It's first consumers are
k8s.io/kubernetes, k8s.io/kube-aggregator, and github.com/kubernetes-incubator/service-catalog.
Compatibility
There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in 2017.
Where does it come from?
apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiserver.
Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.
Things you should NOT do
- Directly modify any files under
pkgin this repo. Those are driven fromk8s.io/kubernetes/staging/src/k8s.io/apiserver. - Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the API isn't yet stable enough for API guarantees.
