17 Run this command in order to set up the Kubernetes control plane
18 The "init" command executes the following phases:
21 preflight Run pre-flight checks
24 kubelet-start Write kubelet settings and (re)start the kubelet
25 certs Certificate generation
26 /ca Generate the self-signed Kubernetes CA to provision identities for other Kubernetes components
27 /apiserver-kubelet-client Generate the certificate for the API server to connect to kubelet
28 /apiserver Generate the certificate for serving the Kubernetes API
29 /front-proxy-ca Generate the self-signed CA to provision identities for front proxy
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 healtcheck 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 addon Install required addons for passing Conformance tests
55 /coredns Install the CoreDNS addon to a Kubernetes cluster
56 /kube-proxy Install the kube-proxy addon to a Kubernetes cluster
57
62 --apiserver-advertise-address=""
63 The IP address the API Server will advertise it's listening on. If
64 not set the default network interface will be used.
65 --apiserver-bind-port=6443
68 Port for the API Server to bind to.
69 --apiserver-cert-extra-sans=[]
72 Optional extra Subject Alternative Names (SANs) to use for the API
73 Server serving certificate. Can be both IP addresses and DNS names.
74 --cert-dir="/etc/kubernetes/pki"
77 The path where to save and store the certificates.
78 --certificate-key=""
81 Key used to encrypt the control-plane certificates in the
82 kubeadm-certs Secret.
83 --config=""
86 Path to a kubeadm configuration file.
87 --cri-socket=""
90 Path to the CRI socket to connect. If empty kubeadm will try to
91 auto-detect this value; use this option only if you have more than one
92 CRI installed or if you have non-standard CRI socket.
93 --dry-run=false
96 Don't apply any changes; just output what would be done.
97 --experimental-upload-certs=false
100 Upload control-plane certificates to the kubeadm-certs Secret.
101 --feature-gates=""
104 A set of key=value pairs that describe feature gates for various
105 features. No feature gates are available in this release.
106 --ignore-preflight-errors=[]
109 A list of checks whose errors will be shown as warnings. Example:
110 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
111 --image-repository="k8s.gcr.io"
114 Choose a container registry to pull control plane images from
115 --kubernetes-version="stable-1"
118 Choose a specific Kubernetes version for the control plane.
119 --node-name=""
122 Specify the node name.
123 --pod-network-cidr=""
126 Specify range of IP addresses for the pod network. If set, the con‐
127 trol plane will automatically allocate CIDRs for every node.
128 --service-cidr="10.96.0.0/12"
131 Use alternative range of IP address for service VIPs.
132 --service-dns-domain="cluster.local"
135 Use alternative domain for services, e.g. "myorg.internal".
136 --skip-certificate-key-print=false
139 Don't print the key used to encrypt the control-plane certificates.
140 --skip-phases=[]
143 List of phases to be skipped
144 --skip-token-print=false
147 Skip printing of the default bootstrap token generated by 'kubeadm
148 init'.
149 --token=""
