spring reactor implementation for case inventory management.

rxinvent aims to implement the latest technology that integrated using

• Spring Boot
• Reactor-MongoDB-Redis-Kafka
• GraalVM
• Docker
• Kubernetes (context-dekstop)
• Prometheus and
• Grafana

It is mandatory for you to have maven, docker and kubernetes installed on your machine.

1. git clone github.com/lloistborn/rxinvent.git
2. run mvn clean package dockerfile:build to build the docker images from this repo on top of GraalVM
3. run docker-compose up to run them all if everyhting was alright then you should see Nettyrunning on port 8080

in separate terminal, make sure all the container running well by using command docker ps. we should see Prometheus, Grafana springio/inventory-management and mongo container are running.

in essence, Actuator brings production-ready features to our application. Monitoring our app, gathering metrics, understanding traffic or the state of our database becomes trivial with this dependency. The main benefit of this library is that we can get production grade tools without having to actually implement these features ourselves.

to run actuator, go to localhost:8080/actuator

by default, whenever we successfully run this project, there are some data inserted to mongo documents.

to check them, run our favorite client and add connection localhost:27017.

Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.

Grafana is an open source visualization tool that can be used on top of a variety of different data stores.

go check prometheus on locahost:9090 and grafana localhost:3000
