Automatic merge from submit-queue (batch tested with PRs 55403, 54660, 55165). 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>. code-generator: add NewFilteredSharedInformerFactory function **What this PR does / why we need it**: Adds a `namespace` option to the SharedInformerFactory constructor. This is useful when building controllers that may need to scope themselves to a namespace due to RBAC constraints. Workarounds for this involve losing type safety if a user wants to use it for core APIs as well as a SharedInformerFactory type interface, as we have to deal with plain SharedIndexInformers (example here: https://github.com/jetstack-experimental/cert-manager/blob/master/pkg/util/kube/factory.go) **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # Fixes https://github.com/kubernetes/code-generator/issues/9 **Special notes for your reviewer**: This will require updating all uses of SharedInformerFactory throughout the codebase. I'm going to follow up with later commits in this PR with these changes, but wanted to get this here to get some feedback on the way it's implemented. **Release note**: ```release-note NONE ``` /cc @sttts @nikhita @deads2k
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>.
