NetMARKS Reproduction

Project Structure

Setup:

Dev Environment

Install Dependencies
- Container manager like Docker, or Podman
- minikube: https://minikube.sigs.k8s.io/docs/start/
- k8s version: v1.27.4
Configure Minikube
- See: https://minikube.sigs.k8s.io/docs/commands/config/
Start Local k8s cluster using minikube
```
minikube start --nodes <nodeCount>
```

minikube

When initializing minikube nodes, only some core dependencies will be installed (dashboard and dns). For the experiment, more setup is needed:

Istio Service Mesh
- https://istio.io/latest/docs/setup/getting-started/
- Remember to enable Envoy sidecar injection!
Install Prometheus & Grafana (optional) using Istio
- https://istio.io/latest/docs/ops/integrations/prometheus/
- https://istio.io/latest/docs/ops/integrations/grafana
Useful Add-ons:
- minikube dashboard
- kubernetes-sigs/metrics-server
Enable Scheduler
- Custom: See following section

Services

Use build-images.sh under <rootDir>/services/ to build mock services and push the images to minikube. Use deployment.yaml under <rootDir>/infra to create deployment. Use services.yaml under <rootDir>/infra to create services

Deployment

Intro

We are doing dev locally, which means we don't push our test service's image to cloud. Thus, we need to load image: See: https://minikube.sigs.k8s.io/docs/handbook/pushing/#7-loading-directly-to-in-cluster-container-runtime

minikube image load <imageName>

Deploy a Pod

kubectl apply -f infra/pods.yaml

Expose/Forward

kubectl port-forward svc/prometheus 9090:9090 -n istio-system

Get All Pods

kubectl get po -A

Envoy sidecar
