25 certs Certificate generation
26 /front-proxy-ca Generates the self-signed CA to provision identities for front proxy
27 /front-proxy-client Generates the client for the front proxy
28 /ca Generates the self-signed Kubernetes CA to provision identities for other Kubernetes components
29 /apiserver Generates the certificate for serving the Kubernetes API
30 /apiserver-kubelet-client Generates the Client certificate for the API server to connect to kubelet
31 /etcd-ca Generates the self-signed CA to provision identities for etcd
32 /etcd-server Generates the certificate for serving etcd
33 /etcd-peer Generates the credentials for etcd nodes to communicate with each other
34 /etcd-healthcheck-client Generates the client certificate for liveness probes to healtcheck etcd
35 /apiserver-etcd-client Generates the client apiserver uses to access etcd
36 /sa Generates a private key for signing service account tokens along with its public key
37 kubeconfig Generates all kubeconfig files necessary to establish the control plane and the admin kubeconfig file
38 /admin Generates a kubeconfig file for the admin to use and for kubeadm itself
39 /kubelet Generates a kubeconfig file for the kubelet to use *only* for cluster bootstrapping purposes
40 /controller-manager Generates a kubeconfig file for the controller manager to use
41 /scheduler Generates a kubeconfig file for the scheduler to use
42 control-plane Generates all static Pod manifest files necessary to establish the control plane
43 /apiserver Generates the kube-apiserver static Pod manifest
44 /controller-manager Generates the kube-controller-manager static Pod manifest
45 /scheduler Generates the kube-scheduler static Pod manifest
46 etcd Generates static Pod manifest file for local etcd.
47 /local Generates the static Pod manifest file for a local, single-node local etcd instance.
48 upload-config Uploads the kubeadm and kubelet configuration to a ConfigMap
49 /kubeadm Uploads the kubeadm ClusterConfiguration to a ConfigMap
50 /kubelet Uploads the kubelet component config to a ConfigMap
51 mark-control-plane Mark a node as a control-plane
52 bootstrap-token Generates bootstrap tokens used to join a node to a cluster
