[Kwokctl]: Added kube-controller-manager certificate for kind and binary runtime

[Manoramsharma]

trafficstars

What type of PR is this?

/kind feature

What this PR does / why we need it:

Currently, all components of kwokctl(etcd, kube-apiserver, kube-controller-manager, kwok-controller) share admin certificates, which is different from kubeadm's behavior, and we try to close to kubeadm's behavior as much as possible. So I tried to generate a component-specific certificate for kube-controller-manager component for kind and binary runtime for now.

After the review I will successfully add the certificates for all the remaining components covering other runtimes also.

Which issue(s) this PR fixes:

Fixes #878

Special notes for your reviewer:

Hi @wzshiming I need a quick review on this implementation as I am going to add component-sepcific certs for other kwokctl components that are presently sharing admin cert.

Hi @Manoramsharma. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi @wzshiming I have tried to add component specific cert for kube-controller-manager, I have handled the generation of component-specific cert by changing GeneratePki function(You can see the changes), changed the configuration parameters of kube-controller-manager for binary runtime by providing the kubeControllerManagerKeyPath and kubeControllerManagerCertPath to addKubeControllerManager function but seeing some failed checks. Can please provide me a quick review to help me figure out what I am missing?

Note: For container runtime (Docker, podman, nerdctl, lima) I haven't changed anything for now.
