This is an implementation of the project discussed in the article on learnk8s.io by Mauricio Salatino where a simple note taking application is created using Java Spring Boot framework, containerized using docker and deployed on a local Kubernetes cluster.
The application used Spring JPA with a MongoDB database and a Minio Object Store, all running as microservices on a kubernetes cluster. I have made some modifications in the source code and configuration parameters based on changes to the components used in the application.
Please setup an application.properties file in the src/main/resources directory with the following lines to get started -
spring.data.mongodb.host=host.docker.internal
spring.data.mongodb.port=27017
If you wish to try running this application on docker, you may pull the container from docker hub using docker pull devanandkmenon/notes-app. I have also placed the kubernetes configuration YAML files under /kube directory.
This repository is intended for educational purposes and does not accept further contributions. Feel free to utilize and enhance the app based on your own requirements.
