Joining a New Worker Node to VelaD Control Plane

This guide describes the steps for joining a new worker node to an existing VelaD control plane.

Prerequisites

Before proceeding with the steps below, ensure that:

• Have a VelaD control plane running.
• You have the token for the VelaD control plane. You can get the token by running the velad token command on the VelaD control plane master node.
• New worker node is Linux machine and can access the VelaD control plane master node.
• You have SSH access to the new worker node

Steps

1. Download VelaD to the new worker node.

curl -fsSl https://static.kubevela.net/script/install-velad.sh | bash

2. Run the velad join command on the new worker node.

   velad join --master-ip <master-ip> --token <token> --worker-name <worker-name>
   

   • <master-ip> is the IP address of the VelaD control plane master node. (Required)
   • <token> is the token for the VelaD control plane. (Required)
   • <worker-name> is the name of the new worker node. (Optional)

3. Verify the new node has joined the control plane.

   • Use kubectl get nodes to check the new worker node has joined the VelaD control plane.

Delete a Worker Node

Run the velad uninstall command on the VelaD on the worker node to be deleted.
