average-price

Sample application to experiment with Spring Boot, Kafka, Influxdb and docker.

Basically, it just display the average of the last X prices on user request, with X an input parameter. The user input/output takes place on the web application.

1. Make sure to have docker compose installed in host machine

$ docker-compose --version
docker-compose version 1.22.0, build f46880fe

2. Start the application

$ docker-compose up

3. Access the application in local environment with http://localhost:8081

1. Influxdb query for the average X price
2. web frontend, to be implemented in data consumer first
3. Dockerize the jars
4. onsolidate the app and the dependencies with docker compose
   • Kafka
   • Influxdb
   • Consumer
   • Producer
5. Extract the web UI into separated services
6. Use Spring Cloud to coordinate with different components
   • Extract the Web UI to a separate spring service from Consumer
   • Externalize configuration in spring-cloud-config
   • Adopt Spring Cloud Eureka for service discovery
   • Web UI invoke Consumer with feign client
7. Deploy the app in kubernetes
