🏗 Build container images for your Java applications.

The goal of this project is to create a simple Spring Boot REST API, called simple-service, and secure it with Keycloak. Furthermore, the API users will be loaded into Keycloak from OpenLDAP server.

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

Sample code and instructions for steps through different container image build options.

The goal of this project is to implement a Spring Boot application, called movies-api, and use Filebeat & ELK Stack (Elasticsearch, Logstash and Kibana) to collect and visualize application's logs and Prometheus & Grafana to monitor application's metrics.

The goal of this project is to implement two Spring Boot applications: bitcoin-api and bitcoin-client. The bitcoin-api application simulates BTC price changes, while the bitcoin-client application listens to these changes and updates a real-time UI. The bitcoin-client UI is secured using Basic Authentication.

Source code examples built for the purpose of video course: Microservices On Kubernetes

The goal of this project is to create a simple Spring Boot REST API, named 'simple-service,' and secure it using the Spring Security LDAP module. Additionally, Testcontainers will be utilized for integration testing.

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

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.

The goal of this project is to explore GraphQL. For it, we will implement two microservices: author-book-api and book-review-api.

The goal of this project is to play with Spring WebFlux on client and server side. For it, we will implement some Spring Boot Java Web applications, product-api, customer-api, order-api and client-shell, and use reactive NoSQL database like Cassandra, MongoDB, Postgres and MySQL.

Demo Java apps for several scenarios on Kubernetes

The goal of this project is to play with RSocket protocol. For it, we will implement three Spring Boot Java applications, movie-server, movie-client-shell and movie-client-ui. As storage, it's used the reactive NoSQL database MongoDB. All the streaming of movie events and the logging are handling by AOP (Aspect Oriented Programming).
