This repository contains an example application for orders processing in a warehouse, with the purpose of trying and showing different technologies. This is a diagram showcasing in high level how the application works.

In this case the application is based on camel-k to implement different components of the application, like the REST API or the Stock Service. Knative eventing is also used, as camel-k is based on knative, and it's used to provide the cannels like the queue and topic showed in the diagram.

First of all a kubernetes or openshift cluster with camel-k, knative serving and knative-eventing operators installed.

The files I used to set up the operators are included as well as a bunch of scripts in the scripts folder to deploy and try the system.

Install camel-k

kamel install --cluster-setup
kamel install

Install knative

oc apply -f infra/operators/openshift-serverless-sub.yaml
oc apply -f infra/knative-serving.yaml
oc apply -f infra/operators/knative-eventing-sub.yaml
oc apply -f infra/knative-eventing.yaml
oc apply -f infra/channels
