How to connect MySQL docker container with spring boot app image for production ?

Hi! I want to run the same spring boot app on my laptop at the time of development with connecting my own installed MySQL and in production with MySQL docker container. I tried more but getting the issue with JDBC connection exception. Please help me.

I am using two files same project for that.

# application.properties for local MySQL connection

spring.datasource.platform=mysql
spring.datasource.driverClassName=com.mysql.jdbc.Driver

spring.datasource.url= jdbc:mysql://localhost:3306/tsbacked?useSSL=false
spring.datasource.username = root
spring.datasource.password = 12345
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

# application.yml for Docker container MySQL

spring:
    jpa:
        database: MYSQL
        hibernate:
            ddl-auto: validate

    datasource:
        url: jdbc:mysql://mysql:3306/tsbacked
        username: root
        password: 12345
        driver-class-name: com.mysql.jdbc.Driver

# Dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD target/techlaviya-0.0.1.jar app.jar
ENV JAVA_OPTS=""
ENTRYPOINT exec java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar

docker run --name demo-mysql -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=tsbackedMYSQL_USER=root-e MYSQL_PASSWORD=12345 -d mysql:5.6

Ohhh I found the solution. You can read this tutorial: https://g00glen00b.be/docker-spring-boot/. The problem is your application load the application.properties. You need to change the ENTRYPOINT to load the profile with the container configuration (application.yml). E.g “-Dspring.profiles.active=container”

spring:
    profiles: container
    jpa:
        database: MYSQL
        hibernate:
            ddl-auto: validate

    datasource:
        url: jdbc:mysql://mysql:3306/tsbacked
        username: root
        password: 12345
        driver-class-name: com.mysql.jdbc.Driver

Running with a database is out of scope for this guide. If you want to see some guidance, maybe open an issue in the extended topical guide.
