Problema na tabela do banco de dados MySQL

Seguindo o enunciado do desafio, eu tinha encontrado um tutorial de como conectar o Spring Boot no MySQL: https://spring.io/guides/gs/accessing-data-mysql.

Eu cheguei modificar os seguintes arquivos:

pom.xml

...
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-docker-compose</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-testcontainers</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.testcontainers</groupId>
            <artifactId>junit-jupiter</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.testcontainers</groupId>
            <artifactId>mysql</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
...

application.yml

spring:
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/forum
    username: 'myuser'
    password: 'secret'
  jpa:
    database-platform: org.hibernate.dialect.MySQL8Dialect
    defer-datasource-initialization: true
    properties:
      hibernate:
        show_sql: true
        format_sql: true

E cheguei a criar este arquivo:

compose.yaml

services:
  mysql:
    image: 'mysql:latest'
    environment:
      - 'MYSQL_DATABASE=forum'
      - 'MYSQL_PASSWORD=secret'
      - 'MYSQL_ROOT_PASSWORD=verysecret'
      - 'MYSQL_USER=myuser'
    ports:
      - '3306:3306'

O problema que estou tendo é que quando executo o postman com uma requisição GET em http://localhost:8080/topicos , recebo a seguinte resposta:

{
    "timeStamp": "2024-09-20T09:11:26.4223736",
    "status": 500,
    "error": "INTERNAL_SERVER_ERROR",
    "message": "JDBC exception executing SQL [select t1_0.id,t1_0.autor_id,t1_0.curso_id,t1_0.data_criacao,t1_0.mensagem,t1_0.status,t1_0.titulo from topico t1_0] [Table 'forum.topico' doesn't exist] [n/a]; SQL [n/a]",
    "path": "/topicos"
}

E é mostrada a seguinte mensagem de erro no console do IntelliJ:

Pelo que é mostrado nessas mensagens, a tabela 'forum.topico' não está sendo criada, quando o Spring Boot inicializa junto com o MySQL no Docker.

O que eu devo fazer para que o Spring Boot crie essa tabela?
