Spring Cloud Config, Spring Cloud Bus & Kafka - How to set up automatic updates of your configuration
Introduction
In this article, I will show you how to achieve automatic updates with Spring Cloud Bus and Kafka
The Spring Cloud Bus, according to documentation:
Spring Cloud Bus links nodes of a distributed system with a lightweight message broker. This can then broadcast state changes (e.g., configuration changes) or other management instructions. AMQP and Kafka broker implementations are included in the project. Alternatively, any Spring Cloud Stream binder on the classpath will work out of the box as a transport.
I will start from common practice nowadays without a message broker.
First, we need to create a repository with your app’s configuration. There is no rocket science to create a new repository. After that, we can edit with web IDE, clone, add, commit, and push the app’s configuration to the remote repository.

echo:
message:
text: 'Hello, World!'The second part is to create a cloud config server and set up the correct configuration for this server. We must set up a remote repository and credentials to make the configuration accessible.
