I am developing a small application using springboot with maven and a mysql db.
I created a Dockerfile that’s working but when I try to do docker-compose up the connection from app to db is refused.

here my docker-compose

version: '3.8'

services:
  app:
    image: jayaz98/angelodaleotest:0.0.1
    ports:
      - 8080:8080
    environment:
      SPRING_DATASOURCE_URL: jdbc:mysql://db:3306/angelodaleoptdb?autoReconnect=true&useSSL=false
      SPRING_DATASOURCE_USERNAME: admin
      SPRING_DATASOURCE_PASSWORD: root
    depends_on:
      db:
        condition: service_healthy

  db:
    image: mysql:8.0.27
    environment:
      DATABASE_HOST: docker-mysql
      DATABASE_PORT: 3306
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: angelodaleoptdb
      MYSQL_USER: admin
      MYSQL_PASSWORD: root
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "localhost"]
      interval: 10s
      retries: 5
      timeout: 5s

my application.properties

spring.application.name=project
spring.datasource.url=jdbc:mysql://localhost:3306/angelodaleoptdb?useSSL=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.hikari.connectionTimeout=100000
spring.datasource.hikari.initializationFailTimeout=0
spring.datasource.hikari.maximumPoolSize=10
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
server.servlet.context-path=/angelodaleopt

and this is the error i get from the app, with the db logs
