30 /front-proxy-client Generate the certificate for the front proxy client
31 /etcd-ca Generate the self-signed CA to provision identities for etcd
32 /etcd-server Generate the certificate for serving etcd
33 /etcd-peer Generate the certificate for etcd nodes to communicate with each other
34 /etcd-healthcheck-client Generate the certificate for liveness probes to healthcheck etcd
35 /apiserver-etcd-client Generate the certificate the apiserver uses to access etcd
36 /sa Generate a private key for signing service account tokens along with its public key
37 kubeconfig Generate all kubeconfig files necessary to establish the control plane and the admin kubeconfig file
38 /admin Generate a kubeconfig file for the admin to use and for kubeadm itself
39 /kubelet Generate a kubeconfig file for the kubelet to use *only* for cluster bootstrapping purposes
40 /controller-manager Generate a kubeconfig file for the controller manager to use
41 /scheduler Generate a kubeconfig file for the scheduler to use
42 control-plane Generate 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 Generate static Pod manifest file for local etcd
47 /local Generate the static Pod manifest file for a local, single-node local etcd instance
48 upload-config Upload the kubeadm and kubelet configuration to a ConfigMap
49 /kubeadm Upload the kubeadm ClusterConfiguration to a ConfigMap
50 /kubelet Upload the kubelet component config to a ConfigMap
51 upload-certs Upload certificates to kubeadm-certs
52 mark-control-plane Mark a node as a control-plane
53 bootstrap-token Generates bootstrap tokens used to join a node to a cluster
54 kubelet-finalize Updates settings relevant to the kubelet after TLS bootstrap
55 /experimental-cert-rotation Enable kubelet client certificate rotation
56 addon Install required addons for passing Conformance tests
57 /coredns Install the CoreDNS addon to a Kubernetes cluster
58 /kube-proxy Install the kube-proxy addon to a Kubernetes cluster
59
64 --apiserver-advertise-address=""
65 The IP address the API Server will advertise it's listening on. If
66 not set the default network interface will be used.
67 --apiserver-bind-port=6443
70 Port for the API Server to bind to.
71 --apiserver-cert-extra-sans=[]
74 Optional extra Subject Alternative Names (SANs) to use for the API
75 Server serving certificate. Can be both IP addresses and DNS names.
76 --cert-dir="/etc/kubernetes/pki"
79 The path where to save and store the certificates.
80 --certificate-key=""
83 Key used to encrypt the control-plane certificates in the
84 kubeadm-certs Secret.
85 --config=""
88 Path to a kubeadm configuration file.
89 --control-plane-endpoint=""
92 Specify a stable IP address or DNS name for the control plane.
93 --cri-socket=""
96 Path to the CRI socket to connect. If empty kubeadm will try to
97 auto-detect this value; use this option only if you have more than one
98 CRI installed or if you have non-standard CRI socket.
99 --dry-run=false
102 Don't apply any changes; just output what would be done.
103 -k, --experimental-kustomize=""
106 The path where kustomize patches for static pod manifests are
107 stored.
108 --feature-gates=""
111 A set of key=value pairs that describe feature gates for various
112 features. Options are: IPv6DualStack=true|false (ALPHA - default=false)
113 PublicKeysECDSA=true|false (ALPHA - default=false)
114 --ignore-preflight-errors=[]
117 A list of checks whose errors will be shown as warnings. Example:
118 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
119 --image-repository="k8s.gcr.io"
122 Choose a container registry to pull control plane images from
123 --kubernetes-version="stable-1"
126 Choose a specific Kubernetes version for the control plane.
127 --node-name=""
130 Specify the node name.
131 --pod-network-cidr=""
134 Specify range of IP addresses for the pod network. If set, the
135 control plane will automatically allocate CIDRs for every node.
136 --service-cidr="10.96.0.0/12"
139 Use alternative range of IP address for service VIPs.
140 --service-dns-domain="cluster.local"

148 --skip-phases=[]
151 List of phases to be skipped
152 --skip-token-print=false
155 Skip printing of the default bootstrap token generated by 'kubeadm
