If you have Docker installed, grab a PostgreSQL image from Docker Hub and run the image.

The PostgreSQL flyway database schemas are located under

reactive-talk-202012/src/main/resources/db/migration

Application properties can be configured in

reactive-talk-202012/src/main/resources/application.properties
