# native-spring-on-k8s-with-graalvm-workshop

This repo contains all the materials required for the `Native Spring on K8s with GraalVM` workshop.

The workshop is designed to help Spring Boot developers build new/modernize existing applications using Spring Native and deploy them to Kubernetes. 

Basic knowledge of Spring Boot and Kubernetes is assumed for successful completion.

---

## Context

This content contains sample code supporting the workshop agenda, with a focus on building Native Applications using Spring Native and GraalVM.

The content is organized around a number of independent sections, each with a `README.md` file explaining how to build and run the samples, 

or pointing out areas of interest, for further exploration. 

The content is geared around the following main areas:

* [Prerequisite Software Setup and Validation](setup/README.md) 

* Understanding [GraalVM](graalvm/README.md)

* Building [Spring Native](spring-native/README.md) Applications with GraalVM

* [Best Practices](best-practices/README.md) for designing native-friendly Spring apps and libraries

* [Complete](complete/README.md) Spring Native examples

----

## Repository

This workshop repository can be cloned to your machine as follows:

```shell

> git clone https://github.com/ddobrin/native-spring-on-k8s-with-graalvm

```

Full samples are provided for each lab or demo! 

All samples are relative to the repository root, for ex.:

```shell

# Petclinic

/complete/petclinic-jdbc

```

---------

## Environment setup and validation

**Please start** by cloning the repo, then **follow** the [environment setup and validation section](setup/README.md) `prior` to the start of the workshop.

---------

## Workshop - Detailed Agenda

1. Introductions

2. [Setup Validation](setup/README.md) - say "Hello Workshop" 

    * **[Hands-on Setup Lab](setup/README.md#Build-Run-App)**

3. Let's get started - How fast are your pets? Let's build some images for them !

    * **[Hands-on Lab #1](complete/petclinic-jdbc/README.md)**

4. Demystifying Native Images

    * Let's talk about JVM vs Native

    * Introducing ahead-of-time compilation (AOT)

    * Making close-world assumptions

    * When to modernize apps with native images ? Let's see the use-cases

5. [Understanding GraalVM](graalvm/README.md)

    * GraalVM Architecture

    * Native Image technology for ahead-of-time compilation

    * Build configuration for a native image build process
