3.7.1 Modify the RDS Security Group

The first step in migrating the database component to Amazon RDS is to ensure that traffic coming from the Amazon Lightsail VPC is allowed to reach Amazon RDS. This step is done by adding the IP address range (‘172.26.0.0/16’) of the Amazon Lightsail VPC to the existing Amazon RDS security group.

  1. Navigate to the Amazon RDS databases page.
  2. From the list of databases, click task-db.
  3. Under the ‘Connectivity’ section, click your ‘VPC security group’.

    Your VPC security group will look similar to rds-launch-wizard (sg-05fde746966bcff7d).

  4. Click the ‘Inbound’ tab.

    This will allow you to access the rules that define what traffic is allowed to reach the Amazon RDS database.

  5. Click ‘Edit’
  6. Click ‘Add rule’ then configure:
  7. Click ‘Save’.
