Overview

Deploying your Java application in a Kubernetes cluster could feel like Alice in Wonderland. You keep going down the rabbit hole and don’t know how to make that ride comfortable. This no-slide and code-only session will explain how a Java application consisting of different microservices can be deployed in a Kubernetes cluster. Specifically, it will explain the following:

-Show a Java application with three microservices -How this application is packaged as a Docker image -Create Kubernetes manifests -How Helm charts are created and hosted in a Helm repository -Test in a local environment such as minikube -Attach debugger (may need to find out if tooling exists in this area) -Install Istio in k8s, show service visibility -Install k8s on AWS -Migrate application from a local cluster to a cluster in the Cloud -Setup deployment pipeline -Use an Alexa skill to scale the application -Change application, show A/B using Istio
