Creating Amazon Aurora DB Cluster with Instances

Overview

Domain expertise for creating complete Amazon Aurora database setups including cluster creation, instance provisioning, and managed password configuration via AWS Secrets Manager. Supports both Aurora MySQL and Aurora PostgreSQL engines.

Create an Aurora cluster with instances

To create a fully configured Aurora database cluster with attached instances, follow the procedure exactly. See Aurora cluster creation procedure.

The procedure creates an empty Aurora cluster first, then adds a database instance to make it queryable. It uses AWS Secrets Manager for password management and includes proper status monitoring with retry logic.

Troubleshooting

Cluster creation fails

Verify the engine version is supported in your region and that you have sufficient permissions for RDS and Secrets Manager operations.

Instance creation fails

Check that the instance class is compatible with the Aurora engine and available in your region's availability zones.

Long creation times

Aurora cluster and instance creation can take 10-20 minutes. Extended wait times are normal for Aurora resources.
