Kubernetesize your Java application

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 can be deployed in a Kubernetes cluster. Specifically, it will explain the following:
• Package the application as Docker image
• Create Kubernetes manifests
• Create Helm charts
• Test in a local k8s cluster
• Debug pods using Java IDE
• Observability using Istio
• Migrate application from dev to prod environments
• Deployment pipeline on desktop and in the cloud

Java from a Parallel Universe

Do you get excited about Java when you’re at a conference, learning about cool new features and tools to try? Do you get sad the next day, when you’re back at work building enterprise applications in an ancient version of Java? You’re not alone. In this talk, we will explore what Java looks like in a Parallel Universe where upgrading to the latest Java doesn’t have to be a hassle, where stacktraces can be read and understood by human beings (that’s you!), and where dependency injection is never confusing. I will show you a Parallel Universe where code is beautiful and simple. I will show you a Parallel Universe where there is no magic. I will show you a Parallel Universe where @Annotations were never invented. Will you join me there?
