Graal Containers

Introduction

Credits: @krisfoster https://github.com/krisfoster/graal-containers

This repo will walk you through building containerised apps with GraalVM JDK and Native Image.

We will be using a Spring Boot application as our test-bed. This is a fairly simple app that generates a nonsense verse, in the style of the poem Jabberwocky (by Lewis Carrol). To do this remarkable feat it uses a Markov chain to model the text of the original poem and this model is then used to generate random text that appear to be like the original.
