Effective Spring + Kubernetes

Both Spring and Kubernetes have massive ecosystems leading to lots of ways to use Spring on Kubernetes. Which way is the best, what are the pros and cons of different approaches to using Spring and Kubernetes?

This workshop is organized as a series of recommendations for how to best use Spring and Kubernetes together in the Style of the Effective Java book. An implementation of each recommendation is available via a GitHub repo, that you will run during the session. The talk assumes no previous knowledge of Kubernetes or containers, we will review the key concepts required during the workshop.

Topics covered include:

• Various ways of building container images with Spring Boot
• Kubernetes health and liveness probes for Spring Boot applications
• Kubernetes CPU and memory limits for Spring Boot applications
• Graceful shutdown for Spring Boot applications on Kubernetes
• How to detect if Spring Boot is running on Kubernetes
• Configuration best practices for spring boot application on Kubernetes
• Spring Boot config tree support on Kubernetes and config best practices

We will be using Spring Boot 2.5 for this workshop since it is scheduled for release on May 20th, 2021. if there are delays in the release in Spring Boot 2.5, we will use the latest release candidates at the time of the workshop.

We do not have enough time in this workshop to cover Spring Cloud on Kubernetes, if you are interested in this topic please check out the “Spring Cloud on Kubernetes” workshop.
