Running a Real Spring Boot App Under Kubernetes

Rather than treating Kubernetes abstractly, this course keeps the scope narrow and concrete: take a single, publicly available Spring Boot Docker image exposing a RESTful API, and get it running properly under Kubernetes. That focus makes it a practical entry point into a famously broad topic.

What You'll Learn

Setting up a local Kubernetes environment for development
Creating a Kubernetes Deployment for a Docker image
Configuring a Kubernetes Service to expose it
Using Spring Boot's Readiness and Liveness probes
Configuring a graceful shutdown for in-progress transactions

Who it's for: developers at any level who already have a Spring Boot app (or plan to) and want to understand deployment on Kubernetes specifically, not container orchestration in general.

Key takeaway: health probes and graceful shutdown are framed as essential production concerns, not optional extras, once an app runs under Kubernetes.

About this course

Kubernetes is a container orchestration system used to automate software deployment, scaling and management.

Effectively, Kubernetes is a management tool direct the running of Docker images.

Kubernetes is actually much more than just a tool to run a Docker image.

However in this course, we will be running a single Docker image under Kubernetes. You will learn how to deploy a simple Spring Boot application (in a Docker image) under Kubernetes.

The course uses a publically available Docker Image. The image contains a Spring Boot Application, which exposes a simple RESTful API.

After learning how to set up a local Kubernetes environment for development, you will learn how to create a Kubernetes Deployment. A Deployment is how Kubernetes defines a Docker container to run.

Next you will learn how to configure a Kubernetes Service. A Service is how you direct Kubernetes to expose deployments to network resources.

Spring Boot has added features to support running in a containerized environment. Two of these are Readiness and Liveness probes.

The Readiness probe accounts for startup period of an application. Once the application has started and is ready for work, the Readiness probe will return a positive result.

The Liveness probe returns a positive result while the application is in a healthy state. Kubernetes can monitor the Liveness probe for application health.

Finally in the course, you will learn to configure a graceful shutdown. This allows the Spring Boot application to complete any inprocess transactions before the container is terminated.
