For the best experience in this learning path, we suggest that you complete the following learning resources in the order shown. When you click on a resource, it will open in a new tab. Keep this page open so you can easily move on to the next resource!

Welcome to the first phase of your Kubernetes Journey! In this tutorial, you will learn about installation via the CLI, how to install Minikube, and how to start Kubernetes. You will also learn about kubectl, pods, replicasets, deployments, services, logs, service magic, and blue/green deployments.

Move your legacy Java application into a container and deploy it to Kubernetes. The Developer Sandbox for Red Hat OpenShift is a free OpenShift cluster that gives you access to cutting-edge technologies built on Kubernetes. A quick sign-up gets you a cluster and access to a set of developer tools and services. Move this Spring Pet Clinic example application into a container using the Source-to-Image (s2i) feature.

This cheat sheet covers the integrations you can find in the form of extensions between Quarkus and Kubernetes.

Learn the fundamentals of Kubernetes in this series of short DevNation Lessons with our amazing CodeCasters!

Welcome to the first phase of your Kubernetes Journey! In this tutorial you will learn about installation via installation via the CLI, how to install Minikube, and how to start Kubernetes.

Red Hat OpenShift is a Kubernetes distribution that makes it easy to deploy and scale applications in the cloud. In this hands-on lab, you will learn how to deploy a full-stack JavaScript application in an OpenShift cluster. Starting from source code, you will take an application that runs locally and deploy it in the Developer Sandbox for Red Hat OpenShift.

Quarkus & Kubernetes II Cheat Sheet

April 30, 2020

This cheat sheet covers more integrations that you can find in the form of extensions between Quarkus and Kubernetes.

The evolution of microservices and containers in recent years significantly changed the the way we design, develop, and run software. Today’s applications are optimized for scalability, elasticity, failure, and speed of change. Driven by new principles, modern architectures require a different set of patterns and practices.

Build an effective development environment and pipeline for containers. This session highlights a few unique developer-focused features that have been included in Red Hat's CNCF-certified distribution of Kubernetes, and features live demos showing how to quickly build, test, and iterate on Java-based solutions via IDE or via command-line. We will also take a tour of the newly-redesigned 'Developer Perspective' web interface for deeper insights on the health and performance of our solutions.

Expand your knowledge while you learn about building images, resources, and limits, rolling updates, liveness, readiness, startup, and config maps.

This cheat sheet covers how to create a Kubernetes Operator in Java using Quarkus.

Using the Free Developer Sandbox for RedHat OpenShift, we will demo how you can take your existing source code or create a new application, easily deploy and manage them as containers, edit the code from our integrated developer experience, and much more.

Build microservices via one of these Java frameworks: Spring Boot, Dropwizard, and WildFly Swarm

In this Spring Boot tutorial, you’ll learn to use Spring Boot when your deployment platform is Kubernetes. Assuming you already know Spring Boot, you’ll learn how to containerize a Spring Boot application with Jib, how to deploy it to a Kubernetes cluster with JKube, spring Actuators to implement health checks and provide metrics, spring Resiliency, spring Cloud Kubernetes Config to inject config maps as Spring configuration properties

A DevNation Live tech talk

Get started with Migration Toolkit for Applications 5.1.0's improved user interface, new Operator, and support for migrating from Spring Boot to Quarkus.

In this scenario, you will learn more about developer application using Spring Boot using Red Hat Runtimes. You will learn how to get started with building a CRUD (Create, Read, Update and Delete) web application.

Introducing Istio Service Mesh for Microservices

Burr Sutter and Christian Posta

April 17, 2019

Red Hatter’s Burr Sutter and Christian Posta introduce you to several key microservices capabilities that Istio provides on Kubernetes and Red Hat OpenShift.

Kamesh Sampath provides an overview of Envoy and Istio, two open source projects that will change the way you write cloud-native Java applications on Kubernetes. We’ll show how to download and set up Istio on your local laptop, then deploy Java microservices as part of the Istio service mesh with Istio sidecar proxy.
