Prerequisites

• Docker
• Docker Compose

Used Technologies

• Java 17: The primary programming language used for the application.
• Spring Boot: Framework for building the application.
• Gradle: Build automation tool used for managing dependencies and building the project.
• Kafka: Distributed streaming platform used for building real-time data pipelines and streaming applications.
• PostgreSQL: Relational database used for storing application data.
• Liquibase: Database schema change management tool.
• Docker: Containerization platform used for packaging the application and its dependencies.
• Docker Compose: Tool for defining and running multi-container Docker applications.
• Lombok: Java library used to reduce boilerplate code.
• JUnit: Testing framework used for unit testing the application.

Development Setup

1. Clone the repository:

   git clone git@github.com:goxan/Assignment.git
   cd Assignment

2. Change application.yml file in src/main/resources folder with your Kafka and PostgreSQL configurations.

3. Build the project:

   ./gradlew build

4. Run the application:

   ./gradlew bootRun

Running with Docker

1. Build the Docker image:

   docker build -t my-app .

2. Start the services with Docker Compose:

   docker-compose up

3. Access the application at http://localhost:8080.

Checking Logs

1. Navigate to the directory where your docker-compose.yml file is located.
2. Use the docker-compose logs command to view the logs. You can specify the service name to view logs for a specific service or omit it to view logs for all services.
