kubeadm - Man Page

• Create a Kubernetes master node: kubeadm init
• Bootstrap a Kubernetes worker node and join it to a cluster: kubeadm join --token token
• Create a new bootstrap token with a TTL of 12 hours: kubeadm token create --ttl 12h0m0s
• Check if the Kubernetes cluster is upgradeable and which versions are available: kubeadm upgrade plan
• Upgrade Kubernetes cluster to a specified version: kubeadm upgrade apply version
• View the kubeadm ConfigMap containing the cluster's configuration: kubeadm config view
• Revert changes made to the host by 'kubeadm init' or 'kubeadm join': kubeadm reset

Example usage:

Create a two-machine cluster with one control-plane node
(which controls the cluster), and one worker node
(where your workloads, like Pods and Deployments run).

┌──────────────────────────────────────────────────────────┐
│ On the first machine:                                    │
├──────────────────────────────────────────────────────────┤
│ control-plane# kubeadm init                              │
└──────────────────────────────────────────────────────────┘

┌──────────────────────────────────────────────────────────┐
│ On the second machine:                                   │
├──────────────────────────────────────────────────────────┤
│ worker# kubeadm join <arguments-returned-from-init>      │
└──────────────────────────────────────────────────────────┘

You can then repeat the second step on as many other machines as you like.

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--rootfs="" [EXPERIMENTAL] The path to the 'real' host root filesystem.

--version=false --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
