What steps are necessary to deploy a worker node in a Kubernetes cluster?

To deploy a worker node in a Kubernetes cluster, the following steps are generally performed:

1. Prepare a server or virtual machine with a supported OS (e.g., Ubuntu).
2. Install necessary dependencies, such as Docker or another container runtime.
3. Install kubeadm, kubelet, and kubectl — the main Kubernetes components.
4. Initialize or join the node to an existing cluster using the kubeadm join command, specifying the master node's address and token.
5. Check the node status with the command kubectl get nodes.

Example command to join a node:

kubeadm join <master-ip>:6443 --token <token> --discovery-token-ca-cert-hash sha256:<hash>

After this, the node becomes part of the cluster and can run pods.
