AWS RDS Instance Restoration with Ansible

This README provides the details of an Ansible playbook script that automates the process of restoring an AWS RDS instance from a snapshot.

Requirements

To run this playbook, you will need:

  • Ansible installed on your local machine or whichever machine you are running this script on.

  • The AWS SDK (boto3 and botocore) installed.

  • An AWS account with the necessary permissions to manage RDS instances and snapshots.

  • The Ansible AWS community collections. You can install these with the following command:

    ansible-galaxy collection install community.aws

Usage

The Ansible playbook (e.g., restore_rds.yml) can be run with the following command:

ansible-playbook restore_rds.yml

Before running the playbook, you need to update the variables section in the playbook:

vars:
  region: us-west-2
  db_instance_identifier: aurora-cluster-demo
  snapshot_identifier: my-cluster-final-snapshot
  restored_db_instance_identifier: restored-instance
  db_engine: aurora-postgresql
  db_instance_class: db.r5.large
  db_username: your_username
  db_password: your_password

Replace the your_username and your_password with your actual master username and password for the DB instance.

What the Script Does

The playbook runs the following tasks:

  1. Ensures that a snapshot exists for the specified RDS instance (community.aws.rds_snapshot module).
  2. Restores a DB instance from the specified snapshot (community.aws.rds_instance module).

AWS Authentication

Be aware of Ansible's AWS authentication. It uses the AWS SDK, so you can use AWS CLI profiles or environment variables. You can find more information in the Ansible AWS Guide.

Disclaimer

Be careful while using this playbook in a production environment as it directly affects your AWS resources. Always test on a small scale or in a testing environment before applying changes at a large scale or in production.
