Improve Your Developer Experience with Spring Boot Dev Services

We all use Docker (and Docker Compose) to provide the external services we develop against, say, a PostgreSQL database.

In this talk, we will show you an upcoming new feature of Spring Boot that will certainly improve your developer experience.
