Code change:
Please note: This issue is not suitable for new contributors since you need some familiarity with how Kubernetes works. The Kubernetes website currently lacks a guide on creating Windows/Linux nodes. See for more details. SIG Windows opted to remove the guide that did exist for creating Windows nodes, in PR Write a new task page about creating nodes for all operating systems. This could, potentially, be in a tabbed format as mentions in the issue referenced above. We would also need the entry reflected on the creates the Linux task page by moving / refactoring the existing "join node" contents from the "create a cluster" page: creates the Windows task page by taking the content from at the end of the Windows page we add note/disclaimer whatever that says that CNI on Windows needs special handling and we link to the various CNI choices at: adds tabs in the to choose between OS for joining nodes. /priority backlog /help

text: <ins> --- title: Adding Linux worker nodes content_type: task weight: 50 --- <!-- overview --> This page explains how to add Linux worker nodes to a kubeadm cluster. ## {{% heading "prerequisites" %}} * Each joining worker node has installed the required components from [Installing kubeadm](/docs/setup/production-environment/tools/kubeadm/install-kubeadm/), such as, kubeadm, the kubelet and a {{< glossary_tooltip term_id="container-runtime" text="container runtime" >}}. * A running kubeadm cluster created by `kubeadm init` and following the steps in the document [Creating a cluster with kubeadm](/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/). * You need superuser access to the node. <!-- steps --> ## Adding Linux worker nodes To add new Linux worker nodes to your cluster do the following for each machine: 1. Connect to the machine by using SSH or another method. 1. Run the command that was output by `kubeadm init`. For example: ```bash sudo kubeadm join --token <token> <control-plane-host>:<control-plane-port> --discovery-token-ca-cert-hash sha256:<hash> ``` ### Additional information for kubeadm join {{< note >}} To specify an IPv6 tuple for `<control-plane-host>:<control-plane-port>`, IPv6 address must be enclosed in square brackets, for example: `[2001:db8::101]:2073`. {{< /note >}} If you do not have the token, you can get it by running the following command on the control plane node: ```bash sudo kubeadm token list ``` The output is similar to this: ```console TOKEN                    TTL  EXPIRES              USAGES           DESCRIPTION            EXTRA GROUPS 8ewj1p.9r9hcjoqgajrj4gi  23h  2018-06-12T02:51:28Z authentication,  The default bootstrap  system: signing          token generated by     bootstrappers: 'kubeadm init'.        kubeadm: default-node-token ``` By default, node join tokens expire after 24 hours. If you are joining a node to the cluster after the current token has expired, you can create a new token by running the following command on the control plane node: ```bash sudo kubeadm token create ``` The output is similar to this: ```console 5didvk.d09sbcov8ph2amjw ``` If you don't have the value of `--discovery-token-ca-cert-hash`, you can get it by running the following commands on the control plane node: ```bash sudo cat /etc/kubernetes/pki/ca.crt | openssl x509 -pubkey  | openssl rsa -pubin -outform der 2>/dev/null |  openssl dgst -sha256 -hex | sed 's/^.* //' ``` The output is similar to: ```console 8cb2de97839780a412b93877f8507ad6c94f73add17d5d7058e91741c9d5ec78 ``` The output of the `kubeadm join` command should look something like: ``` [preflight] Running pre-flight checks ... (log output of join workflow) ... Node join complete: * Certificate signing request sent to control-plane and response received. * Kubelet informed of new secure connection details. Run 'kubectl get nodes' on control-plane to see this machine join. ``` A few seconds later, you should notice this node in the output from `kubectl get nodes`. (for example, run `kubectl` on a  control plane node). {{< note >}} As the cluster nodes are usually initialized sequentially, the CoreDNS Pods are likely to all run on the first control plane node. To provide higher availability, please rebalance the CoreDNS Pods with `kubectl -n kube-system rollout restart deployment coredns` after at least one new node is joined. {{< /note >}} ## {{% heading "whatsnext" %}} * See how to [add Windows worker nodes](/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes/). </ins>
