Automatic merge from submit-queue Add metric for remaining lifetime of certificates authenticating requests fixes #50778 When incoming requests to the API server are authenticated by a certificate, the expiration of the certificate can affect the validity of the authentication. With auto rotation of certificates, which is starting with kubelet certificates, the goal is to use shorter lifetimes and let the kubelet renew the certificate as desired. Monitoring certificates which are approaching expiration and not renewing would be an early warning sign that nodes are about to stop participating in the cluster. **Release note**: ```release-note Add new Prometheus metric that monitors the remaining lifetime of certificates used to authenticate requests to the API server. ```
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-apiserver
k8s.io/api
k8s.io/apimachinery
k8s.io/apiserver
k8s.io/client-go
k8s.io/kube-aggregator
k8s.io/kube-gen
(about to be published)k8s.io/metrics
k8s.io/sample-apiserver
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>
.
