+# Cilium Component
+
+## Overview
+
+Cilium is our CNI (Container Network Interface) solution that provides networking, security, and observability for Kubernetes using eBPF.
+
+## Configuration
+
+The following configurations are available:
+
+- Version: 1.18.3
+- IPAM Mode: kubernetes
+- Hubble UI: Enabled
+- L2 Announcements: Enabled
+- kube-proxy Replacement: Enabled
+
+## Features
+
+- **Hubble UI**: Web interface for network observability
+- **L2 Announcements**: For LoadBalancer service type support
+- **Enhanced Security**: Using eBPF for network policy enforcement
+- **Kube-proxy Replacement**: Native handling of service load-balancing
+
+## Post-Install
+
+After installation:
+
+1. Cilium core components will be installed
+2. Hubble UI and Relay will be deployed
+3. LoadBalancer IP pools will be configured
+4. Initial access to Hubble UI is available through port-forward:
+
+   ```bash
+   kubectl port-forward -n kube-system svc/hubble-ui 12000:80
+   ```
+
+   Then visit: `http://localhost:12000`
+
+## Dependencies
+
+- Kubernetes cluster
+- Helm v3+
+- Linux kernel >= 4.9.17
+
+## Troubleshooting
+
+1. Check if Cilium pods are running:
+
+   ```bash
+   kubectl get pods -n kube-system -l k8s-app=cilium
+   ```
+
+2. Check Cilium status (requires Cilium CLI):
+
+   ```bash
+   cilium status
+   ```
+
+3. Check Hubble UI deployment:
+
+   ```bash
+   kubectl get deployment -n kube-system hubble-ui
+   ```
+
+4. View Cilium logs:
+
+   ```bash
+   kubectl logs -n kube-system -l k8s-app=cilium
+   ```
+
+To install Cilium CLI:
+
+```bash
+brew install cilium-cli
+```

+## Configuration
+
+The following configurations are available:

+- Domain: argocd.noxxos.nl
+- Ingress: Enabled with Traefik
+- Version: 9.1.0
+
+## Post-Install
+
+After installation:
+
+1. The admin password will be displayed
+2. Initial access is available through port-forward:
