Hey everyone! I'm currently exploring Kubernetes by migrating a microservice that uses Spring Boot and Kafka from Docker Compose. This is part of a learning project for me, and I want to share my progress to help anyone else who might be on a similar path. I've documented everything and created some resources:
- Check out my blog post detailing my hands-on experience with this migration.
- You'll also find my code in a GitHub repository.
Right now, I'm focusing on getting the basic Kubernetes deployment set up and configuring the Kafka consumer. The next challenge is setting up monitoring, so any advice on that would be super helpful! I'd love to hear from anyone who's done similar projects—what surprised you most during your own migrations?

I did a Spring Boot microservice migration a while back too, and the biggest surprise was how important configuration management became. Using ConfigMaps and Secrets made life a lot easier! Don’t forget to explore those options!
That sounds like an exciting project! The transition to Kubernetes can be pretty rewarding. One thing that really surprised me when I did a similar migration was the learning curve with setting up persistent storage. It can be quite different from how you handle it in Docker Compose. Definitely spend some time on that!
I totally agree! Setting up volumes for Kafka in Kubernetes was a bit tricky for me too. It’s worth checking out StatefulSets for better management.
Yes! Using ConfigMaps was a game changer for my environment variables. It really helped in keeping things organized and manageable.
