AWS Configuration Setup

We use IAM Identity Center to manage users and groups, so access keys are not enabled. To set up SSO authentication locally, please follow this AWS documentation.

Connect to the DB Instance via Bastion Host

To connect to the RDS instance using a Bastion Host, follow these steps:

• Deploy the bastion-host.

• Run the following command to establish a port forwarding session:

  aws ssm start-session --target <ec2-instance-id> --document-name AWS-StartPortForwardingSessionToRemoteHost --parameters '{\"host\":[\"<rds-endpoint>\"],\"portNumber\":[\"3306\"],\"localPortNumber\":[\"3306\"]}'

  • Replace <ec2-instance-id> with your Bastion Host's EC2 instance ID.
  • Replace <rds-endpoint> with the Aurora Cluster Writer Endpoint to ensure connectivity to the primary writable database instance.

• Open a database tool such as MySQL Workbench and connect to localhost:3306.
