Kubernetes-commit: d2f7eb5235a93556261c8947e7a87342aeeaee2b
This package contains public/private key utilities copied directly from
client-go/util/cert. All imports were updated.
Future PRs will actually refactor the libraries.
Updates #71004
Kubernetes-commit: 18458392ca24c85c688e655aace1afd04f864cbd
* When user try execute command like `kubectl get pod test -o custom-columns=CONTAINER:.spec.containers[-1].name`
It will throw a panic about slice index out of bounds. This patch fix it.
* add test case

Revert "Ensure the bootstrap rotation code is tested by forcing rotation"
This reverts commit de293b2d7ddb687850258370f2a7f30f224f0ec1.
Kubernetes-commit: 34642222676640b3c1dd255cc453000f2743ccde
Expose both a Stop() method (for cleanup) and a method to force
cert rotation, but only expose Stop() on the interface.
Verify that we choose the correct client.

Ensure that bootstrap+clientcert-rotation in the Kubelet can:
1. happen in the background so that static pods aren't blocked by bootstrap
2. collapse down to a single call path for requesting a CSR
3. reorganize the code to allow future flexibility in retrieving bootstrap creds
Fetching the first certificate and later certificates when the kubelet
is using client rotation and bootstrapping should share the same code
path. We also want to start the Kubelet static pod loop before
bootstrapping completes. Finally, we want to take an incremental step
towards improving how the bootstrap credentials are loaded from disk
(potentially allowing for a CLI call to get credentials, or a remote
plugin that better integrates with cloud providers or KSMs).
Reorganize how the kubelet client config is determined. If rotation is
off, simplify the code path. If rotation is on, load the config
from disk, and then pass that into the cert manager. The cert manager
creates a client each time it tries to request a new cert.
Preserve existing behavior where:
1. bootstrap kubeconfig is used if the current kubeconfig is invalid/expired
2. we create the kubeconfig file based on the bootstrap kubeconfig, pointing to
the location that new client certs will be placed
3. the newest client cert is used once it has been loaded

This func is only used by the kubelet and there's no need to pollute
client-go API with it.
Kubernetes-commit: 5c073abfe16fc0b9f62310b8276fc3b0c7043e60
This func is only used internally and was copied from
k8s.io/kubernetes/pkg/apis/certificates.

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Kubernetes-commit: 954996e231074dc7429f7be1256a579bedd8344c
With the current behavior, when kubelet starts, a `templateChanged`
event is always fired off because it only checks if `getLastRequest`
matches `getTemplate`. The last request only exists in memory and thus
is initially `nil` and can't ever match the current template during
startup.
This causes kubelet to request the signing of a new CSR every time it's
restarted. This commit changes the behavior so that `templateChanged` is
only fired off if the currently template doesn't match both the current
certificate and the last template.

certificate.FileStore only handles (cert, key) combined PEM files. This
PR allows (key, cert), which is what "openssl req -out foo.pem -keyout
foo.pem" generates.
