🏗 Build container images for your Java applications.

sbt version of sbt jib: https://github.com/GoogleContainerTools/jib

The goal of this project is to compare some Java Microservice Frameworks like: Quarkus, Micronaut and Spring Boot. For it, we will implement applications using those frameworks, build their JVM and Native Docker images and measure start-up times, memory footprint, etc.

Project goal: Explore Kafka, Kafka Connect, and Kafka Streams. Components: store-api: Inserts/updates MySQL records. Source Connectors: Monitor MySQL changes, push messages to Kafka. Sink Connectors: Listen to Kafka, insert/update Elasticsearch docs. store-streams: Listens to Kafka, processes with Kafka Streams, pushes new messages to Kafka.

The goal of this project is to implement a "News" processing pipeline composed of five Spring Boot applications: producer-api, categorizer-service, collector-service, publisher-api and news-client.

The goal is to explore Axon. We will develop a food-ordering app comprising 3 Spring Boot applications: customer-service, restaurant-service, and food-ordering-service. These services are implemented with CQRS and Event Sourcing, utilizing the Axon Framework. They connect to axon-server, which serves as the Event Store and Message Routing solution.

Goal: create a Spring Boot application that handles users using Event Sourcing. So, whenever a user is created, updated, or deleted, an event informing this change is sent to Kafka. Also, we will implement another application that listens to those events and saves them in Cassandra. Finally, we will use Testcontainers for end-to-end testing.

In this project, we will implement two Spring Boot Java Web application called, streamer-data-jpa and streamer-data-r2dbc. They both will fetch 1 million of customer's data from MySQL and stream them to Kafka. The main goal is to compare the application's performance and resource utilization.

The goal of this project is to explore the capabilities of Vault. To achieve this, we will develop applications that utilize Vault for storing and retrieving secrets. Vault dynamically generates credentials for accessing databases and relies on Consul as the backend. The authentication method employed in Vault is AppRole.

Continuous Delivery to Kubernetes with Kotlin, Ktor, Gradle, Jib, Skaffold and Kubernetes (EKS)

The goal is to play with Spring Kafka. We've implemented 5 examples of producer and consumer services that exchanges messages through Kafka using different types of serialization and approaches.

The goal of this project is to implement an application called product-app. It consists of two Spring Boot services: product-api (backend) and product-ui (frontend). Data will be stored in Elasticsearch
