Playing with OpenShift 4 locally

January 2018, Red Hat acquired CoreOS for 250 million dollars 🤩. CoreOS was one of the leading companies of Linux & Containers market with their wide offer of products:

  • CoreOS Tectonic: container application platform based on Kubernetes.
  • CoreOS Container Linux: lightweight Linux distribution designed to run containerized applications.
  • CoreOS Operators Framework: an open source toolkit designed to manage Kubernetes native applications.
  • CoreOS Quay: a container registry for building, storing, and distributing your private containers.
  • CoreOS rkt: an application container engine developed for modern production cloud-native environments.
  • even more and more..

Playing with Java under the shield of SonarQube

Introduction

We.. developers.. we spend all our time writing code (and drinking coffee).. but we rarely care about the code quality.. until we get some pressure from a reviewer or from some quality scanner tool.. and as every field in the Java ecosystem, we have many choices when we come to choose a Quality Scanner tool: FindBugs, CheckStyle, PMD and of course the GREATEST SonarQube 😍

I fully worked with SonarQube since January 2014, during my M.Sc. internship to analyze my code and even to check if there are some Security Flaws using the OWASP and SANS Quality Gates.

In this tutorial, I will show you how to get started with SonarQube and how to use it lightly (without even installing it) 😁

Playing with Istio Service Mesh on Kubernetes

What is Istio?

Google presents Istio as an open platform to connect, monitor, and secure microservices.

Istio is a service mesh implementation that provides many cloud-native capabilities like:

  • Traffic management: Service Discovery, Load balancing, Failure recovery, A/B testing, Canary releases, etc…
  • Observability: Request Tracing, Metrics, Monitoring, Auditing, Logging, etc…
  • Security: ACLs, Access control, Rate limiting, End-to-end authentication, etc…

Istio delivers all these great features without any changes to the code of the microservices running with it on the same Kubernetes cluster.

In our case, we already implemented many of these features and capabilities when we were writing our microservices. If we had Istio at the beginning, we could save so much effort and time, by delegating all of these capabilities to Istio.

  • I started working on Istio Tutorial that will be the first bonus chapter in the book ⚡️⚡️

I will be covering more and more subjects soon 😁

I am available for an on-demand chapters. So if you are interested in some specific subject about Java Microservices, just get in touch with me 😁

My new book is here !!

Playing with Java Microservices on Kubernetes and OpenShift is here !

Today, November 24th 2018, I released my new book Playing with Java Microservices on Kubernetes and OpenShift!! Finally, after ten months of work, tests, POCs and many edition iterations, the newborn is here !

The book is edited and sold on the LeanPub platform 🤩

The book is sold mainly in two different offers:

  • The Book only
  • The Book + one hour of training about Java Microservices and Kubernetes/OpenShift

I have some ideas about making some other packages, I will post about them soon ! Stay tuned !!

I hope that this book satisfies all your needs about the Java Microservices in the Kubernetes and OpenShift ecosystem..

Many other subjects will be covered.. Yeah ! LeanPub gives me the opportunity to deliver as many updates that I can write 😀 this is cool ! you pay once, you get everything !!

You can grab it from Leanpub or Amazon 😎

Playing with Spring Boot on Kubernetes

I. Introduction

In this tutorial I will show you how to write a small Spring Boot CRUD application and how to deploy it on Kubernetes.

Spring Boot is an innovative project that aims to make it easy to create Spring applications by simplifying the configuration and deployment actions through its convention over configuration based setup.

Kubernetes (commonly referred to as “K8s”) is an open-source system for automating deployment, scaling and management of containerized applications that was originally designed by Google and now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It works with a range of container tools, including Docker.

Docker is an open source project that automates the deployment of applications inside software containers.

This tutorial is a getting started point to the Spring Boot & K8s stack.

New version of “Playing with Spring Boot and Docker in NetBeans IDE”

This article is originally published April 13th, 2017 at JaxEnter website: Link

In this tutorial you will learn how to write a Java EE application using two of the trendiest technologies: Spring Boot and Docker in NetBeans IDE.

Spring Boot is an innovative project that aims to make it easy to create Spring applications by simplifying the configuration and deployment actions through its convention over configuration based setup. Docker is an open source project that automates the deployment of applications inside software containers.

Today I’d like to make a tutorial in which a simple Spring Boot application is deployed using Docker.
