Run this command in order to set up the Kubernetes control plane
The "init" command executes the following phases:
preflight Run pre-flight checks
kubelet-start Write kubelet settings and (re)start the kubelet
certs Certificate generation
/ca Generate the self-signed Kubernetes CA to provision identities for other Kubernetes components
/apiserver Generate the certificate for serving the Kubernetes API
/apiserver-kubelet-client Generate the certificate for the API server to connect to kubelet
/front-proxy-ca Generate the self-signed CA to provision identities for front proxy
/front-proxy-client Generate the certificate for the front proxy client
/etcd-ca Generate the self-signed CA to provision identities for etcd
/etcd-server Generate the certificate for serving etcd
/etcd-peer Generate the certificate for etcd nodes to communicate with each other
/etcd-healthcheck-client Generate the certificate for liveness probes to healthcheck etcd
/apiserver-etcd-client Generate the certificate the apiserver uses to access etcd
/sa Generate a private key for signing service account tokens along with its public key
kubeconfig Generate all kubeconfig files necessary to establish the control plane and the admin kubeconfig file
/admin Generate a kubeconfig file for the admin to use and for kubeadm itself
/kubelet Generate a kubeconfig file for the kubelet to use *only* for cluster bootstrapping purposes
/controller-manager Generate a kubeconfig file for the controller manager to use
/scheduler Generate a kubeconfig file for the scheduler to use
control-plane Generate all static Pod manifest files necessary to establish the control plane
/apiserver Generates the kube-apiserver static Pod manifest
/controller-manager Generates the kube-controller-manager static Pod manifest
/scheduler Generates the kube-scheduler static Pod manifest
etcd Generate static Pod manifest file for local etcd
/local Generate the static Pod manifest file for a local, single-node local etcd instance
upload-config Upload the kubeadm and kubelet configuration to a ConfigMap
/kubeadm Upload the kubeadm ClusterConfiguration to a ConfigMap
/kubelet Upload the kubelet component config to a ConfigMap
upload-certs Upload certificates to kubeadm-certs
mark-control-plane Mark a node as a control-plane
bootstrap-token Generates bootstrap tokens used to join a node to a cluster
kubelet-finalize Updates settings relevant to the kubelet after TLS bootstrap
/experimental-cert-rotation Enable kubelet client certificate rotation
addon Install required addons for passing Conformance tests
/coredns Install the CoreDNS addon to a Kubernetes cluster
/kube-proxy Install the kube-proxy addon to a Kubernetes cluster
kubeadm init [flags]
--apiserver-advertise-address string | |
The IP address the API Server will advertise it's listening on. If not set the default network interface will be used. | |
--apiserver-bind-port int32 Default: 6443 | |
Port for the API Server to bind to. | |
--apiserver-cert-extra-sans stringSlice | |
Optional extra Subject Alternative Names (SANs) to use for the API Server serving certificate. Can be both IP addresses and DNS names. | |
--cert-dir string Default: "/etc/kubernetes/pki" | |
The path where to save and store the certificates. | |
--certificate-key string | |
Key used to encrypt the control-plane certificates in the kubeadm-certs Secret. | |
--config string | |
Path to a kubeadm configuration file. | |
--control-plane-endpoint string | |
Specify a stable IP address or DNS name for the control plane. | |
--cri-socket string | |
Path to the CRI socket to connect. If empty kubeadm will try to auto-detect this value; use this option only if you have more than one CRI installed or if you have non-standard CRI socket. | |
--dry-run | |
Don't apply any changes; just output what would be done. | |
-k, --experimental-kustomize string | |
The path where kustomize patches for static pod manifests are stored. | |
--feature-gates string | |
A set of key=value pairs that describe feature gates for various features. Options are: IPv6DualStack=true|false (ALPHA - default=false) PublicKeysECDSA=true|false (ALPHA - default=false) |
|
-h, --help | |
help for init | |
--ignore-preflight-errors stringSlice | |
A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks. | |
--image-repository string Default: "k8s.gcr.io" | |
Choose a container registry to pull control plane images from | |
--kubernetes-version string Default: "stable-1" | |
Choose a specific Kubernetes version for the control plane. | |
--node-name string | |
Specify the node name. | |
--pod-network-cidr string | |
Specify range of IP addresses for the pod network. If set, the control plane will automatically allocate CIDRs for every node. | |
--service-cidr string Default: "10.96.0.0/12" | |
Use alternative range of IP address for service VIPs. | |
--service-dns-domain string Default: "cluster.local" | |
Use alternative domain for services, e.g. "myorg.internal". | |
--skip-certificate-key-print | |
Don't print the key used to encrypt the control-plane certificates. | |
--skip-phases stringSlice | |
List of phases to be skipped | |
--skip-token-print | |
Skip printing of the default bootstrap token generated by 'kubeadm init'. | |
--token string | |
The token to use for establishing bidirectional trust between nodes and control-plane nodes. The format is [a-z0-9]{6}\.[a-z0-9]{16} - e.g. abcdef.0123456789abcdef | |
--token-ttl duration Default: 24h0m0s | |
The duration before the token is automatically deleted (e.g. 1s, 2m, 3h). If set to '0', the token will never expire | |
--upload-certs | |
Upload control-plane certificates to the kubeadm-certs Secret. |
--rootfs string | |
[EXPERIMENTAL] The path to the 'real' host root filesystem. |
