When completing the installation of the Entrust PKI Hub cluster in one node, you can add more nodes to the cluster.

To add Entrust PKI Hub nodes

1. Run the clusterctl node info command to list the nodes already in the cluster.
2. In a node already in Entrust PKI Hub cluster, run the clusterctl node join-token command to get the joining token.
3. Deploy the Recommended number of nodes.
4. In the new nodes: 
   1. Configure the Requirements.
   2. Install the product image as explained in Installing the Entrust PKI Hub image. 

   3. Ensure no restriction blocks access to the Required open ports. 

   4. Open a command-line interpreter and run the clusterctl node add command using the join token obtained in the first step. Do not run this command simultaneously in different nodes of the same Entrust PKI Hub deployment.

      When running this command in AWS or Azure cloud installations, use the private IP of the nodes.

5. Redeploy each deployed Entrust solution (if any) using either the clusterctl solution deploy command or the Management Console.
