This repository demonstrates how to hot reload configuration for a Spring application using Kubernetes and AWS. The examples are split into two branches, each showcasing a different approach.

For a visual walkthrough, watch the file walkthrough.mp4 stored in this repository.

Branch: watcher

This approach utilizes the Spring Cloud Kubernetes Configuration Watcher to dynamically reload configuration changes. This requires specific Kubernetes permissions to function correctly.

• Kubernetes Permissions: Refer to the k8s folder for more details on the necessary permissions.
• Documentation: For a detailed explanation of how the watcher works, refer to the Spring Cloud Kubernetes Configuration Watcher documentation.

Branch: parameter-store

This approach uses AWS Parameter Store to manage and reload configuration properties. You will need to set up IAM credentials, either through environment variables or an IAM role.

• IAM Credentials: Set up IAM credentials using environment variables or an IAM role.
• Documentation: For more information, refer to the AWS Spring Cloud documentation.

To get started with either approach, switch to the respective branch.

# For Kubernetes Configuration Watcher
git checkout watcher

# For AWS Parameter Store
git checkout parameter-store
