Microservices Project 2 | 3 | ## Overview 4 | 5 | This repository contains a collection of fully completed microservices built with Spring Boot version 3.2.5 and Java 17. The project utilizes Spring Cloud version 2023.0.1 for implementing various distributed system patterns and features. 6 | 7 | ## Microservices Description 8 | 9 | 1. **Config Server** 10 | - Provides centralized configuration for all microservices. 11 | - Uses Spring Cloud Config Server. 12 | 13 | 2. **Customer Service** 14 | - Manages customer data and operations. 15 | - Integrated with Eureka Discovery. 16 | 17 | 3. **Discovery Service** 18 | - Service registry using Netflix Eureka. 19 | - Enables service discovery for other microservices. 20 | 21 | 4. **Gateway Service** 22 | - API Gateway for routing requests to appropriate microservices. 23 | - Uses Spring Cloud Gateway. 24 | - Includes distributed tracing and circuit breaker. 25 | 26 | 5. **Notification Service** 27 | - Handles notifications and alerts. 28 | - Uses Kafka for messaging. 29 | 30 | 6. **Order Service** 31 | - Manages orders and their statuses. 32 | - Integrated with Eureka Discovery. 33 | 34 | 7. **Payment Service** 35 | - Processes payments. 36 | - Uses Eureka Discovery and Zipkin for tracing. 37 | 38 | 8. **Product Service** 39 | - Manages product information. 40 | - Integrated with Eureka Discovery. 41 | 42 | ## Features 43 | 44 | - **Service Discovery**: All microservices register with the Eureka server for easy discovery. 45 | - **Centralized Configuration**: Configurations are managed centrally using the Spring Cloud Config Server. 46 | - **API Gateway**: Spring Cloud Gateway is used for routing and handling cross-cutting concerns like security, monitoring, and resilience. 47 | - **Distributed Tracing**: Zipkin is used for tracing requests across microservices. 48 | - **Circuit Breaker**: Circuit breaking capabilities provided by Spring Cloud Circuit Breaker. 49 | - **Messaging**: Kafka is used for asynchronous communication between microservices. 50 | 51 | ## Prerequisites 52 | 53 | - Java 17 or later 54 | - Maven or Gradle 55 | - Docker (optional, for containerized deployment) 56 | 57 | ## Running the Microservices 58 | 59 | 1. **Clone the repository** 60 | ```sh 61 | git clone https://github.com/PramithaMJ/fully-completed-microservices.git 62 | cd fully-completed-microservices 63 | ``` 64 | 65 | 2. **Start Config Server** 66 | ```sh 67 | cd config-server 68 | mvn spring-boot:run 69 | ``` 70 | 71 | 3. **Start Discovery Service** 72 | ```sh 73 | cd discovery 74 | mvn spring-boot:run 75 | ``` 76 | 77 | 4. **Start Other Microservices** 78 | Start the remaining microservices in any order. Ensure they are configured to register with the Discovery Service. 79 | 80 | ```sh 81 | cd 82 | mvn spring-boot:run 83 | ``` 84 | 85 | ## Configuration 86 | 87 | Each microservice has its configuration properties defined in the `application.yml` or `application.properties` file. The Config Server properties should be specified in a central configuration repository. 88 | 89 | ## Deployment 90 | 91 | To deploy the microservices using Docker, use the Dockerfile available in each microservice directory. You can build and run the Docker images as follows: 92 | 93 | ```sh 94 | cd 95 | docker build -t :latest . 96 | docker run -d -p : :latest 97 | ``` 98 | 99 | ## Contributing 100 | 101 | 1. Fork the repository. 102 | 2. Create your feature branch (`git checkout -b feature/your-feature`). 103 | 3. Commit your changes (`git commit -m 'Add some feature'`). 104 | 4. Push to the branch (`git push origin feature/your-feature`). 105 | 5. Open a pull request. 106 | 107 | ## License 108 | 109 | This project is licensed under the MIT License. 110 | 111 | ## Contact 112 | 113 | For any questions or feedback, please open an issue in the repository. 114 | 115 | Thank you, 116 | Pramitha Jayasooriya 117 | https://pramithamj.live 118 | 119 | 122 | ## Donation 123 | 124 | ***If you like what I do, maybe consider buying me a coffee*** 125 | 126 | Buy Me A Coffee 127 | 128 | *** 129 | -------------------------------------------------------------------------------- /docker-compose.yml: -------------------------------------------------------------------------------- 1 | services: 2 | postgresql: 3 | container_name: ms_pg_sql 4 | image: postgres 5 | environment: 6 | POSTGRES_USER: alibou 7 | POSTGRES_PASSWORD: alibou 8 | PGDATA: /data/postgres 9 | volumes: 10 | -
