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 part 2 of this post, we will refactor the application written in part 1 in order to use a database. We will take a short look at the choices we have when selecting a database in combination with Spring WebFlux, use an embedded version of the database, refactor the sources and find solutions for the problems we encounter. The code can be found at GitHub in branch mongodb.
In this post we will continue exploring the capabilities of Spring WebFlux by means of creating a basic CRUD application. We will not be using a database in this post because I did not want to be distracted with database stuff at this moment 😉 Adding a database will be handled in part 2. Furthermore, we will implement a few CRUD operations and see how we can unit test a Flux. Source code can be found at GitHub.
