Spring Boot 3.1 Docker Compose Support

Spring Boot 3.1 Docker Compose Support
4 min read


Spring Boot 3.1 was released on 18th May 2023. It included quite many features and one of them is the support for docker compose.

Today we will look at how we can use this.

Creating an Application

Go to and create a new project.

We will create a simple JPA application that communicates with MySQL.

For this, add the following dependencies.

  • Spring Web ( only required to make REST endpoints)
  • Spring Data JPA.
  • MySQL Driver

Now, the new dependency that needs to be added is “Docker Compose Support”.


This dependency will help us start our docker-compose file when the application starts up.

After downloading the zip file and opening it, we would see already docker-compose file created for us.

Isn’t that incredible? 😃

Knowing that we added a MySQL dependency, the docker-compose file was already ready with the MySQL docker image.

    image: 'mysql:latest'
      - 'MYSQL_DATABASE=mydatabase'
      - 'MYSQL_PASSWORD=secret'
      - 'MYSQL_ROOT_PASSWORD=verysecret'
      - 'MYSQL_USER=myuser'
      - '3306'

Now let's store some data in the database.

Storing Data In Mysql with JPA

Let’s create a simple model class

public class Model {

    private int id;

    @Column(name = "name")
    private String name;


And create an endpoint to accept data and store it in the database.

public class WebController {

   private ModelRepository modelRepository;

   public WebController(ModelRepository modelRepository) {
       this.modelRepository = modelRepository;

   public Model add(@RequestBody Model model) {


We will use the same model class to be parsed from the REST endpoint to the database. But it's always a good practice to always have a DTO (Data Transfer Object).

Now, let’s start the application.

Starting the Application With Docker Compose

On starting the application and making a REST request we are able to store the information in the database.

Rest endpoint calls

But wait, we dint give any configuration properties to set up connections with the database. 🤔

That’s the beauty of this docker compose support dependency.

It automatically starts the docker compose file, and it knows what are the properties set in the file and creates connections for our application.

The only property we have to set is to ally Hibernate to create the DDL statements.
