Warehouse manager

This repository contains a WarehouseManager demo application written in dotnet 8 and c#. It provides a HTTP Api to add/remove/update and query warehouse items from a local sqlite database.

Besides the WarehouseManager contained in ./WarehouseManager it contains kubernetes definition to deploy the app on a local Kubernetes Cluster. These can be found in the ./deployment folder.

Getting started

1. Start the app

Run the following command:

dotnet run --project WarehouseManager/WarehouseManager.csproj

The app will be available at localhost:5086

2. Local development: Start needed services

Even though the app is working without any dependencies to other services, it does not send any telemetry that we can analyze later.

To do that a few services must be up and running:

• OTel Collector
• Prometheus (for metrics)
• Grafana

This can be archived using the following command:

docker compose up -d

2. Deploy app to k8s cluster

Make sure you have the following tools installed:

• k3d Theoretically any k8s cluster should work, but this one is tested
• kubectl The k8s cli
• helm The package manager for k8s

Now simply run the following command to build the WarehouseManager image and deploy it to the cluster:

cd deployment
./deploy.sh

Forward ports to access services in the cluster:

kubectl port-forward services/kube-prometheus-stack-grafana 3000:80 -n monitoring
kubectl port-forward service/warehousemanager 5086:5086 -n warehousemanager
