5 Creating a Server Cluster : 5.2 Cloning a Server Cluster : 5.2.1 Using a Template to Clone a Cluster

A clone deployed with a template will be an exact duplicate of the original master node, but will adhere to the cluster deployment rules described in the template by the system administrator. If you are a Template Only user, you will be required to use a template when cloning a cluster. A non-Template Only user may find it easier (especially when cloning a number of clusters) to use a template to define the properties that are common to multiple deployments.

Figure 5.12 - Creating a clone of a database.
When the Create clone... dialog opens (see Figure 5.12), provide values in the requested fields:
Use the Template 이름 drop-down listbox to select a template that will be used for the new cluster; to review the cluster details associated with the template, click the Full Template Details link.
If applicable, use the 가용성 Zone drop-down listbox to specify the availability zone in which the new cluster will be created.
If applicable, use the Subnet drop-down listbox to select a subnet that will be used by the new cluster.
Use the fields in the Configure Network 보안 Rules section to define security rules that allow access to the cluster. By default, the load balancer port is open to any IP address for client connections; you may choose to delete the rule, and specify a more restrictive IP range.
To delete a rule from the list, highlight the rule and click the Delete Rule button; you will be prompted to confirm that you wish to delete the entry before the server removes the rule.
Click the Add Rule button to open the Add Rule dialog (see Figure 5.5) and provide access to a port.

On the Add Rule dialog:
Use the Port drop-down listbox to select the port that can be accessed from the specified CIDR. A non-administrative user can allow access to ports:
9999 - for client connections and load balancing.
5432 or 5444 - the cluster specific database listener port.
An administrative user can use the Add Rule dialog to add a rule that allows SSH access to Port 22.
Use the CIDR field to specify the address (or address range) that will be allowed access to the server through the selected port.
When you're finished, click Apply to create the security rule.
After providing the details for the cluster, click the Clone button to create the clone of the cluster; select Cancel to exit the dialog without creating a cluster.
