Thank you

Hi thank you for giving the information. i am facing issue with dataSource

-----------

app propertes file : -
spring.datasource.url=jdbc:postgresql://localhost:5432/student-db
spring.datasource.username=postgres
spring.datasource.password=admin
spring.jpa.show-sql=true

## Hibernate Properties
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto=create

spring.application.name=student-service
server.port=8086

-------------------------
dockerfile

FROM openjdk:17
WORKDIR /app
COPY target/student-service-1.0.0.jar .
EXPOSE 8085
ENTRYPOINT ["java","-jar","student-service-1.0.0.jar"]
-------------------------------------------

docker compose :

version: "2"

restart: always
backend:
build: .
container_name: studentservice_container

environment:
db-url: jdbc:postgresql://db:5432/student-db

restart: always

--------------------------

suggest here to overcome the data source issue

When i add the dynamic variables ${db-url} etc and try to build my springboot application there is a error for connectivity with postgresql server. I think its because there is not container for postgres yet and therefore no DB , when should I build the springboot application with those changes or without them ??

Thank you very much for help. It would be much cooler if you do git repo for every video.
