Kubelet certificate rotation. : network クラスターではどのように証明書が使われているのか Kubernetesは下記の用途でPKIを必要とします: kubeletがAPIサーバーの認証をするためのクライアント証明書 APIサーバー Information Enable kubelet client certificate rotation. Description Enable kubelet client certificate rotation. This is well reflected by the official docs: Warning: On nodes created with kubeadm init, prior to kubeadm version Problem Statement K3s has no facilities to regenerate certificates once generated. Not sure if this relates to: #8440 #3817 Description I'm still trying to wrap my head around this kubelet certificate This check ensures that the RotateKubeletServerCertificate argument is set to true, enabling the automatic rotation of the Kubelet's server certificate, which improves security by ensuring that the When configures rotateCertificates: true, the kubelet sends out the client CSR at approximately 70%-90% of the total lifetime of the certificate, then the kube-controler-manager watches kubelet client Disable kubelet serving certificate rotation by updating the node pool using the az aks nodepool update command with the aks-disable-kubelet-serving-certificate-rotation=true tag. By default, these certificates are issued with one year expiration so that they kubelet 进程接收 --rotate-certificates 参数，该参数决定 kubelet 在当前使用的 证书即将到期时，是否会自动申请新的证书。 kube-controller-manager 进程接收 --cluster-signing-duration On agent nodes, kubelet and kube-proxy are restarted once the node certificates are replaced. Certificate Rotation By default, certificates in RKE2 To make the kube-apiserver process requests from current kubelet we need to update apiserver certificate and key along with front-proxy-ca Install during bootstrap We will want to ensure that new certificates for the kubelets are approved automatically. Enable kubelet server certificate rotation. Rationale RotateKubeletServerCertificate causes the kubelet to both request a serving certificate after bootstrapping its client credentials and Kubelet server certificate rotation should be enabled. x.
