can't run containers in javaee correctly

Question

I am getting acquainted with Docker and i need to inject it to my application. I have some problems:

My container always fall down and restarts, may be somebody faced a docker-compose in JavaEE application with MySQL.

My dockerfile:

FROM maven:3.6.3-jdk-11

COPY ./ ./

RUN mvn clean package

CMD ["java", "-war","target/javaee_rest_jdbc_todo_list.war"]

docker-compose file

version: "3.7"
services:
  api_service:
    build: .
    hostname: api_service
    restart: always
    ports:
      - 8090:8080
    depends_on:
      - mysql_db
  mysql_db:
    image: "mysql:8.0"
    hostname: mysql_db
    restart: always
    ports:
      - 3308:3306
    environment:
      MYSQL_DATABASE: javaee_task_db
      MYSQL_USER: user228
      MYSQL_PASSWORD: user228
      MYSQL_ROOT_PASSWORD: 13574637480326

Also i have flyway plugin in my pom.xml file:

        <plugin>
          <groupId>com.googlecode.flyway</groupId>
          <artifactId>flyway-maven-plugin</artifactId>
          <version>1.5</version>
          <configuration>
            <user>user228</user>
            <password>user228</password>
            <driver>com.mysql.jdbc.Driver</driver>
            <url>jdbc:mysql://mysql_db:3308/javaee_task_db?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;connectionCollation=utf8_general_ci&amp;characterSetResults=UTF-8</url>
          </configuration>
        </plugin>

And my dataSourse url connection:

    final static String URL = "jdbc:mysql://mysql_db:3308/javaee_task_db?useSSL=false";

I also attach link to github - https://github.com/MatveyAndrosyukk/javaee_rest_jdbc_todo_list .

I will be veery grateful for your help!

Answer 1

First issue I notice is that the DataSourse URL should use the DB port within a docker network, ie, 3306
