Creating a database cluster

You can create a database cluster from a template (if you have one) or create the new cluster from scratch.

Starting points

The starting point for creating a cluster can be either the Estate page or a project page. When you start from the Estate page, you specify the project where you want to create the database. When you start from a project page, you're creating the database in that project.

To start from the Estate page:

1. Select Quick Actions > Create New Database Cluster.

   If you have more than one project, you're prompted to select a project.

2. If prompted, select the project you want to create the database in.

   After you select the project, or if you have only one project, the Create Cluster Choose your path page opens.

To start from a project page, you can use either of these approaches. To get to a project page, from the Projects page, select the project.

• In the project page, select Create New > Database Cluster.

• In the project page, select Clusters > Postgres Cluster. On the Clusters page, select Create New* > Database Cluster.

In both cases, the Create Cluster "Choose your path" page opens.

Choose your path

On the Choose Your Path page, you specify whether you want to create a cluster from a predefined template or from scratch as a custom build.

• To create the cluster from any available template, select Use Template. See Creating a cluster from a template.

• If no templates are available, or if you want to create a cluster from scratch, select Custom Build.

You can also launch template creation from here by selecting Create New Template. See Create a database cluster template.

Creating a cluster from scratch

After you select Custom Build, you can start to specify your new cluster.

On the Cluster Info tab, select the cluster type:

• Single node
• High availability
• Advanced high availability
• Distributed high availability

Select the tab you want to work on, or step through the tabs in order using Next. If you select Advanced High Availability or Distributed High Availability, instead of the DB Configuration and Additional Settings tabs, you see the Data Groups tab.

• Cluster Info
• Cluster Settings
• DB Configuration (optional)
• Additional Settings (optional)
• Data Groups (for distributed high-availability clusters)

Create the cluster

After you finish configuring the tabs, select Create Cluster. Tabs with incorrect or missing settings show a red indicator. Correct any errors and select Create Cluster again.

After you select Create Cluster with valid settings, the cluster begins provision, and you return to the list of clusters. A popup confirms the creation of the cluster, and the new cluster is added to the list of clusters. The cluster is created in the background. You can see the progress in the list of clusters.

If you try to view the cluster details while the cluster creation is in progress, you can see only the overview, backup, logs, and properties.
