🏗 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.

Kubernetes for the busy developer - A practical guide
Source code examples built for the purpose of video course: Microservices On Kubernetes
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.
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.
A shopping application designed with microservices architecture
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.
Demo Java apps for several scenarios on Kubernetes
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.
