In part 1 of this post, we learned how to create a Spring Boot application, create a Docker image for it and push it to a Docker registry. At the end, we installed Minikube in an Ubuntu VM. In this second part, we will get familiar with some Kubernetes terminology, deploy the application to our Minikube cluster and update the application. The sources used for the application can be found at GitHub. The Docker registry which we use can be found here (or you can use your own Docker registry).
In this post we will take a look how we can build a Spring Boot application, create the Docker image, deploy it to a Docker registry and deploy it to a Kubernetes cluster. This will give us the opportunity to get acquainted with the basics from building an application up to deploying it to Kubernetes. Sources can be found at GitHub.
In this post we will take a look at Project Lombok and what it has to offer us. Project Lombok reduces boilerplate code by making use of annotations in your code. Main advantage is achieved with POJO’s (Plain Old Java Objects): you don’t have to code getters and setters anymore. Although your IDE provides the possibility to generate getters and setters, with Project Lombok you also don’t have to read them anymore. Source code used in this post can be found at GitHub.
