Additionally, to simplify the use of AWS managed services, we will use [`Spring Cloud AWS`](https://spring.io/projects/spring-cloud-aws). 4 | 5 | > **Note**: Also, take a look at the [`springboot-aws-localstack-opensearch-s3-secretsmanager`](https://github.com/ivangfr/springboot-aws-localstack-opensearch-s3-secretsmanager) repository. There, we have implemented two Spring Boot applications for indexing and searching movies. We also used LocalStack to simulate AWS Cloud services locally, such as [`OpenSearch`](https://aws.amazon.com/opensearch-service/), [`S3`](https://aws.amazon.com/s3/), and [`Secrets Manager`](https://aws.amazon.com/secrets-manager/). 6 | 7 | ## Proof-of-Concepts & Articles 8 | 9 | On [ivangfr.github.io](https://ivangfr.github.io), I have compiled my Proof-of-Concepts (PoCs) and articles. You can easily search for the technology you are interested in by using the filter. Who knows, perhaps I have already implemented a PoC or written an article about what you are looking for. 10 | 11 | ## Additional Readings 12 | 13 | - \[**Medium**\] [**Spring Boot apps to trigger and consume DynamoDB News table updates using AWS Lambda, SNS and SQS**](https://medium.com/@ivangfr/spring-boot-apps-to-trigger-and-consume-dynamodb-news-table-updates-using-aws-lambda-sns-and-sqs-957570cf9a3a) 14 | - \[**Medium**\] [**Spring Boot Apps for Movie Indexing/Search with AWS OpenSearch, S3 and Secrets Manager**](https://medium.com/@ivangfr/spring-boot-apps-for-movie-indexing-search-with-aws-opensearch-s3-and-secrets-manager-a95ad0697e51) 15 | - \[**Medium**\] [**Implementing a Spring Boot App using AWS DynamoDB as database**](https://medium.com/@ivangfr/implementing-a-spring-boot-app-using-aws-dynamodb-as-database-5dbf8b7fc924) 16 | - \[**Medium**\] [**Implementing a Spring Boot App that uses AWS Secrets Manager to store its MongoDB credentials**](https://medium.com/@ivangfr/implementing-a-spring-boot-app-that-uses-aws-secrets-manager-to-store-its-mongodb-credentials-f805a4c74d9a) 17 | - \[**Medium**\] [**Implementing a Serverless AWS Lambda with Spring Cloud Function & AWS Adapter**](https://medium.com/@ivangfr/implementing-a-serverless-aws-lambda-with-spring-cloud-function-aws-adapter-05fd6d48ba45) 18 | - \[**Medium**\] [**Using AWS SNS and SQS to stream Alerts from a Spring Boot producer to consumers**](https://medium.com/@ivangfr/using-aws-sns-and-sqs-to-stream-alerts-from-a-spring-boot-producer-to-consumers-0b0a974e40fc) 19 | 20 | ## Project Diagram 21 | 22 | ![project-diagram](documentation/project-diagram.jpeg) 23 | 24 | ## Applications 25 | 26 | - ### news-producer 27 | 28 | [`Spring Boot`](https://docs.spring.io/spring-boot/index.html) Java Web application that exposes a REST API to manage news. It uses DynamoDB as database. 29 | 30 | It has the following endpoints: 31 | ```text 32 | GET /api/news 33 | GET /api/news/{id} 34 | POST /api/news {"title": "..."} 35 | POST /api/news/randomly 36 | DELETE /api/news/{id} 37 | ``` 38 | 39 | - ### dynamodb-lambda-function 40 | 41 | [`Spring Cloud Function`](https://spring.io/projects/spring-cloud-function) application that uses [`AWS Adapter`](https://docs.spring.io/spring-cloud-function/reference/adapters/aws-intro.html) to convert it to a form that can run in `AWS Lambda`. 42 | 43 | `dynamodb-lambda-function` listens to events emitted by an event-source created to monitor changes in `DynamoDB` news table. Once it receives an event, it processes it and publishes a news event to an `SNS` topic. Later, `SNS` publishes the news event to a `SQS` queue. 44 | 45 | - ### news-consumer 46 | 47 | `Spring Boot` Java Web application that polls the news events that are queued in a `SQS` queue. 48 | 49 | ## Prerequisites 50 | 51 | - [`Java 21`](https://www.oracle.com/java/technologies/downloads/#java21) or higher; 52 | - A containerization tool (e.g., [`Docker`](https://www.docker.com), [`Podman`](https://podman.io), etc.) 53 | 54 | ## Package dynamodb-lambda-function jar 55 | 56 | - In a terminal, make sure you inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder: 57 | 58 | - Run the following script: 59 | ```bash 60 | ./package-dynamodb-lambda-function-jar.sh 61 | ``` 62 | When `Maven` packaging finishes, the jar file generated in `dynamodb-lambda-function/target` folder is copied to `dynamodb-lambda-function/shared` folder. 63 | 64 | ## Start and Initialize LocalStack 65 | 66 | - In a terminal, make sure you are in inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder: 67 | 68 | - Start `LocalStack` Docker container: 69 | ```bash 70 | DEBUG=1 docker compose up -d 71 | ``` 72 | 73 | - \[Optional\] Debug logs are enabled so that we have more insights about what is happening. To monitor `localstack` Docker container logs, run the command below: 74 | ```bash 75 | docker logs localstack 76 | ``` 77 | 78 | - Initialize `LocalStack` by running the following script: 79 | ```bash 80 | ./init-localstack.sh 81 | ``` 82 | The script will create: 83 | - create `news-topic` in `SNS`; 84 | - create `news-consumer-queue` in `SQS`; 85 | - subscribe `news-consumer-queue` to `news-topic`; 86 | - create `news` table in `DynamoDB`; 87 | - create `ProcessDynamoDBEvent` Lambda function; 88 | - create an `event-source-mapping` to connect `DynamoDB` to `ProcessDynamoDBEvent` Lambda function. 89 | 90 | ## Running applications with Maven 91 | 92 | - **news-producer** 93 | 94 | In a terminal and, inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder, run the following command: 95 | ```bash 96 | export AWS_REGION=eu-west-1 && export AWS_ACCESS_KEY_ID=key && export AWS_SECRET_ACCESS_KEY=secret && \ 97 | ./mvnw clean spring-boot:run --projects news-producer 98 | ``` 99 | 100 | - **news-consumer** 101 | 102 | In another terminal and, inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder, run the command below: 103 | ```bash 104 | export AWS_REGION=eu-west-1 && export AWS_ACCESS_KEY_ID=key && export AWS_SECRET_ACCESS_KEY=secret && \ 105 | ./mvnw clean spring-boot:run --projects news-consumer 106 | ``` 107 | 108 | ## Running applications as Docker container 109 | 110 | - ### Build Docker images 111 | 112 | In a terminal and, inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder, run the following script: 113 | ```bash 114 | ./build-docker-images.sh 115 | ``` 116 | 117 | - ### Run Docker containers 118 | 119 | - **news-producer** 120 | 121 | In a terminal, run the following command: 122 | ```bash 123 | docker run --rm --name news-producer -p 9080:9080 \ 124 | -e AWS_REGION=eu-west-1 -e AWS_ACCESS_KEY_ID=key -e AWS_SECRET_ACCESS_KEY=secret \ 125 | --network=springboot-aws-localstack-dynamodb-lambda-sns-sqs_default \ 126 | ivanfranchin/news-producer:1.0.0 127 | ``` 128 | 129 | - **news-consumer** 130 | 131 | In a new terminal, run the command below: 132 | ```bash 133 | docker run --rm --name news-consumer -p 9081:9081 \ 134 | -e AWS_REGION=eu-west-1 -e AWS_ACCESS_KEY_ID=key -e AWS_SECRET_ACCESS_KEY=secret \ 135 | -e NEWS_PRODUCER_URL=http://news-producer:9080 \ 136 | --network=springboot-aws-localstack-dynamodb-lambda-sns-sqs_default \ 137 | ivanfranchin/news-consumer:1.0.0 138 | ``` 139 | 140 | ## Application URL 141 | 142 | | Application | Type | URL | 143 | |-----------------|---------|---------------------------------------| 144 | | `news-producer` | Swagger | http://localhost:9080/swagger-ui.html | 145 | | `news-consumer` | UI | http://localhost:9081 | 146 | 147 | ## Playing around 148 | 149 | - **Creating news** 150 | 151 | - In a terminal, run the following command: 152 | ```bash 153 | curl -i -X POST http://localhost:9080/api/news \ 154 | -H 'Content-Type: application/json' \ 155 | -d '{"title": "Palmeiras is three-time champion of the Copa Libertadores da América"}' 156 | ``` 157 | 158 | or to create news randomly: 159 | ```bash 160 | curl -i -X POST http://localhost:9080/api/news/randomly 161 | ``` 162 | 163 | - In `news-consumer` UI, the news should be displayed. 164 | 165 | - **Deleting news** 166 | 167 | - In a terminal, run the following command: 168 | ```bash 169 | curl -i -X DELETE http://localhost:9080/api/news/ 170 | ``` 171 | 172 | - In `news-consumer` UI, the news should be removed. 173 | 174 | ## Demo 175 | 176 | In the `GIF` below, we use `news-producer` Swagger UI to create one random news. Then, we delete the news created previously. Finally, we create more two more news randomly. 177 | 178 | ![demo](documentation/demo.gif) 179 | 180 | ## Shutdown 181 | 182 | - To stop the applications, go to the terminal where they are running and press `Ctrl+C`; 183 | - To stop and remove Docker Compose containers, network, and volumes, go to a terminal and, inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder, run the following command: 184 | ```bash 185 | docker compose down -v 186 | ``` 187 | 188 | ## Cleanup 189 | 190 | To remove the Docker images created by this project, go to a terminal and, inside the `springboot-aws-localstack-dynamodb-lambda-sns-sqs` root folder, run the script below: 191 | ```bash 192 | ./remove-docker-images.sh 193 | ``` 194 |
