Last updated: 2020-11-24 17:56:15


    This document describes how to add nodes to the edge cluster that you created.


    Prepare as instructed below:

    • Node source: you can use an existing server in the CVM console or the ECM console, or a server on another platform or in your on-premises data center.
    • Node processor: supports x86_64, ARM, and ARM64.
    • The following operating systems of nodes are supported:
      • Ubuntu 18.04 and 16.04
      • CentOS 7.6, 7.5, and 7.4
      • Tencent Linux Release 2.4 and 2.2 (Final)
      • SUSE Linux Enterprise Server 12 SP3
      • Debian 9.0
    • Ensure that wget, systemctl, and iptable have been installed on the node to be added.
    • The node network must be able to actively access the internet.


    1. Log in to the Tencent Cloud TKE console and click Edge Clusters in the left sidebar.
    2. On the Edge Clusters page, click the cluster ID to go to the Deployment management page.
    3. In the left sidebar, choose Node Management > Node to go to the Node List page.
    4. On the Node List page, click Add a node.
    5. In the Add a node window that appears, complete the following steps to obtain the node initialization script.
      1. Obtain the initial configuration from the Configure step. You can modify the following parameters:
        • Interface: indicates the network interface used by the node to communicate within the private network.
        • NodeName: indicates the name of the node in the cluster. This name must be unique in the cluster.
      2. Click Next: install. If you are prompted to enable public network access, click to enable it.
      3. In the Install step, copy the script download command for downloading the node initialization script.
    6. Log in to the prepared server, switch to the root account, and run the copied command.
    7. Run the following commands to execute the node initialization script.
      chmod +x script.sh
    8. After the script is successfully executed, go to the "Node List" page and refresh it to check that the newly added node exists.
      You can also perform other node operations, such as draining, removing, cordoning, or uncordoning a node, and editing the node label.
