Joining Nodes in a Cluster

Clustering allows you to group multiple nodes into a single cluster, enabling resource sharing, redundancy, and centralized management within Pextra Cloud.

tip

After installation, each node initially operates as a standalone cluster with one node. You can join additional nodes to an existing cluster using a clustering key.

Creating and Joining a Cluster

Follow these steps to join nodes into an existing cluster:

  1. Log in directly to the node’s management interface.
    • You should see one cluster and one node listed.
  2. In the left navigation panel, click on Cluster.
  3. On the right-hand panel, click on the Cluster you want to extend.
  4. Obtain the Clustering Key for that cluster.
    Cluster Key
  5. Copy the clustering key.
  6. Log in to each new node using its IP address and port 5007 (for example, https://<node-ip>:5007).
  7. In the left navigation panel of each new node, click Cluster.
  8. Click Join Cluster.
  9. Paste the clustering key obtained earlier into the provided field and confirm the operation.
  10. Return to the main cluster view.
  11. You should now see the newly added node listed as a member of the cluster.

Once the process is complete, all joined nodes operate under a unified cluster, enabling centralized management of workloads, networking, and resources.
