# MetalCheck Backend
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 and export.
---
## 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.

# 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
```bash
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:
```bash
kubectl apply -f examples/k8s/rbac.yaml
kubectl apply -f examples/k8s/deployment.yaml
```
### Access the Service
Retrieve the LoadBalancer IP:
```bash
kubectl get svc -n metalcheck
```
Test the API:
```bash
curl http://<EXTERNAL-IP>/k8s/data
```
## Kubernetes Integration
The `/k8s/data` endpoint retrieves information about:
- Nodes: CPU, memory, and allocatable pods.
- Namespaces: List of all namespaces in the cluster.
## Endpoints
| Method | Endpoint | Description |
| --- | --- | --- |
| GET | /metal/data | Get all physical node data |
| POST | /metal/data | Add a new physical node |
| GET | /vm/data | Get all virtual machine data |
| POST | /vm/data | Add a new virtual machine |
| GET | /k8s/data | Get Kubernetes cluster information |
| GET | /export | Export data in JSON or YAML format |
