On This Lesson 4 topics

This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.

In this lesson

let Spring Boot start the stack during development.

Spring Boot (3.1 or later; verify version before recording) can detect compose.yaml and run docker compose up when the app starts.
Add the spring-boot-docker-compose dependency (development scope).
It creates connection details for known services such as PostgreSQL, so you need not hard-code URLs.
On shutdown it stops the containers, controlled by spring.docker.compose.lifecycle-management.
It is a development tool; production uses the real configuration.

Draft outline details

the Maven dependency and the app logs "Started docker compose" and then connecting to the database port chosen by Compose.

Is Compose integration meant for production?
