Automatic merge from submit-queue (batch tested with PRs 60054, 60202, 60219, 58090, 60275). 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>. Fixes for HTTP/2 max streams per connection setting **What this PR does / why we need it**: 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; see https://github.com/golang/net/blob/master/http2/server.go). 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). **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes #60042 **Special notes for your reviewer**: **Release note**: ```release-note Introduced `--http2-max-streams-per-connection` command line flag on api-servers and set default to 1000 for aggregated API servers. ```
External Repository Staging Area
This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.
Repositories currently staged here:
k8s.io/apiextensions-apiserverk8s.io/apik8s.io/apimachineryk8s.io/apiserverk8s.io/client-gok8s.io/kube-aggregatork8s.io/code-generatork8s.io/metricsk8s.io/sample-apiserverk8s.io/sample-controller
The code in the staging/ directory is authoritative, i.e. the only copy of the code. You can directly modify such code.
Using staged repositories from Kubernetes code
Kubernetes code uses the repositories in this directory via symlinks in the
vendor/k8s.io directory into this staging area. For example, when
Kubernetes code imports a package from the k8s.io/client-go repository, that
import is resolved to staging/src/k8s.io/client-go relative to the project
root:
// pkg/example/some_code.go
package example
import (
"k8s.io/client-go/dynamic" // resolves to staging/src/k8s.io/client-go/dynamic
)
Once the change-over to external repositories is complete, these repositories
will actually be vendored from k8s.io/<package-name>.
