I have a RDS instance running Postgres DB with IAM Authentication enabled. I Want to configure the Spring Boot R2DBC connection. All the Database related information like Hostname, port, Database name are already available on the Kubernetes volume mount, so don’t want to put these in the application.properties. The application has rds-db:connect IAM permission. But I’m not sure how to put the configurations in the application for DB connection. Also I’m planning to use Liquibase with the application. If anyone has information on how this can be achieved , it will be very helpful.
