Application Configuration

spring.application.name=kanban-app
server.port=8085
spring.datasource.url=jdbc:postgresql://${POSTGRES_HOST:localhost}:${POSTGRES_PORT:5432}/kanban
spring.datasource.username=${POSTGRES_USER:postgres}
spring.datasource.password=${POSTGRES_PASSWORD:root}
spring.jpa.hibernate.ddl-auto=create
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=true
spring.cloud.config.enabled=false

Application Dockerization

Dockerize the postgres database

sudo docker pull postgres
sudo docker run -d --name postgres -p 5432:5432 -e POSTGRES_PASSWORD=root -e POSTGRES_USERNAME=postgres postgres
sudo docker logs postgres  # check logs to see if the database is running
# Create the database called kanban
sudo docker exec -it postgres bash
psql -h localhost -U postgres

Dockerize the Spring Boot application

FROM openjdk:17-oracle
VOLUME /tmp
ADD target/kanban-task-management-app*.jar /app.jar
CMD ["java", "-jar", "/app.jar", "--spring.profiles.active=prod"]
EXPOSE 8085

The application is then built and run using the following commands:

sudo docker build -t kanban-app .
# For local containerization (using the local postgres database)
sudo docker run -d --name kanban-backend -p 8090:8085 -e POSTGRES_HOST=172.17.0.2 -e POSTGRES_PORT=5432 -e POSTGRES_USERNAME=postgres -e POSTGRES_PASSWORD=root kanban-backend

🔮 Future Scope :

Future iterations of the application may include:

🤝 Real-time Collaboration: Implementing features for real-time collaboration on tasks among multiple users.
🌟 Enhanced User Experience: Continual refinement of the user interface and user experience based on user feedback.
📊 Advanced Analytics: Introducing analytics and reporting features to track productivity and task progress.
