Software Architecture with Spring 5.0

depends_on

Using the depends_on option, you can specify the order in which the service should start. One service can have dependencies on more than one service, if that's needed.

version: '3.1'services:    database:        image: mysql:5        ports:            - "3306:3306"        volumes:          # Use this option to persist the MySQL data in a shared           volume.            - db-data:/host/absolute/path/.mysql        environment:            - MYSQL_ROOT_PASSWORD=example            - MYSQL_DATABASE=demo        application:        image: enriquezrene/docker-compose-banking-app:1.0        ports:            - "8081:8080"        depends_on:            - database        environment:            - spring.datasource.url=jdbc:mysql://database:3306/demo            - spring.datasource.password=example        links:            - database
