MetalCheck is a backend service that provides real-time insights into virtual machines, physical nodes, and Kubernetes clusters. It supports deployment in an EKS environment and offers features like data aggregation, export, and pseudographics visualization.

Features

Metal Nodes: Track hardware details like CPU, memory, and storage for physical nodes.
Virtual Machines: Monitor VMs from cloud providers like Hetzner.
Kubernetes Clusters: Query Kubernetes clusters to gather node and namespace data.
Data Export: Export collected data in JSON or YAML format.
Pseudographics: Terminal-based data visualization (optional).

Setup and Deployment

Prerequisites

Python 3.10+
Docker and kubectl installed
Access to an EKS cluster
AWS CLI configured with appropriate permissions

Build and Deploy

Build and Push Docker Image

docker build -t metalcheck-backend .
docker tag metalcheck-backend:latest <your-ecr-repo>:latest
docker push <your-ecr-repo>:latest

Deploy to EKS

Apply RBAC and deployment configurations:

kubectl apply -f app/example/k8s/rbac.yaml
kubectl apply -f app/example/k8s/deployment.yaml

Access the Service

Retrieve the LoadBalancer IP:

kubectl get svc -n metalcheck

Test the API:

curl http://<EXTERNAL-IP>/k8s/data
