I am learing Docker and encountered an error is that I have created a basic CRUD springboot application which create,getById and getAll Users then configure the Dockerfile and then docker-compose.yml. once I run docker-compose up, its starts creating images and containers and I can see that they are running perfectly ( the status is running ) but they are not creating user tables in MySQL or in simple it is not running the Springboot application just running dockerfile and docker-compose.yml..

Dockerfile

FROM openjdk:21
LABEL authors="MohammedKhadeer"
WORKDIR /usr/src/myapp
COPY . /usr/src/myapp/
#ENTRYPOINT ["java", "-jar","./target/docker-0.0.1-SNAPSHOT.jar"]
CMD ["java", "-jar","./target/docker-0.0.1-SNAPSHOT.jar"]

docker-compose.yml
