Attaching a GridGain 9 Cluster
This page explains how to attach a GridGain 9 cluster to GridGain Nebula.
You can attach as many clusters as your license supports.
Start the Cluster
-
Follow the GridGain 9 documentation to start the cluster.
-
Copy aside the URL address of the cluster as you will need it to connect to the cluster from within Nebula.
Configure Access Ports
Open egress ports 10300 and 10800 to Nebula’s GCP Cloud NAT IP address - 35.209.75.152 - in the cluster firewall rules. The above address will be used to access the cluster from Nebula.
For AWS-based clusters:
-
Create a GridGain 9 cluster based on AWS EC2 instances.
-
Configure firewall rules using AWS security groups - add the
10300and10800ports to the security group’s inbound rules with35.209.75.152/32as the source.
