Project: Kube-Prometheus

1. Install using Helm Chart helm install kube-prometheus oci://ghcr.io/prometheus-community/charts/kube-prometheus-stack -n monitoring --create-namespace
2. Create a ServiceMonitor: kubectl apply -f ./k8s/Prometheus/ServiceMonitor.yml
3. Prometheus & Grafana Dashboards can be accessed with:
   • Prometheus: kubectl --namespace monitoring port-forward svc/prometheus-operated 9090
   • Grafana: kubectl --namespace monitoring port-forward svc/kube-prometheus-grafana 3000:80

Run: task <service>:port-forward

1. Create .env file:

CONFIG_SERVER_URI=http://localhost:8888
SPRING_PROFILES_ACTIVE=local
POSTGRES_USER=<user>
POSTGRES_PASSWORD=<password>

2. Add "envFile": "${workspaceFolder}/.env" to .vscode/launch.json:

{
    "type": "java",
    "name": "ProductServiceApplication",
    "request": "launch",
    "mainClass": "productservice/de.jodabyte.springonk8slab.productservice.ProductServiceApplication",
    "projectName": "product-service",
    "envFile": "${workspaceFolder}/.env"
}

3. Port-Forward PostgreSQL and Config Server

Open (Swagger UI)[http://localhost:8081/swagger-ui.html]

1. The Event Generator needs the .env file
2. Add "envFile": "${workspaceFolder}/.env" to .vscode/launch.json:

{
    "type": "java",
    "name": "EventGeneratorApplication",
    "request": "launch",
    "mainClass": "de.jodabyte.springonk8slab.eventgenerator.EventGeneratorApplication",
    "projectName": "event-generator",
    "envFile": "${workspaceFolder}/.env"
}

3. Port-Forward Config-Server and Product-Service
