MetalLB

MetalLB is an open-source load balancer implementation for Kubernetes clusters running on bare-metal, on-premises, and self-managed environments. It enables Kubernetes services of type LoadBalancer to obtain external IP addresses, allowing applications to be accessed from outside the cluster without relying on a cloud provider's load-balancing service.

Features of MetalLB :

• Open-source load balancer designed for bare-metal Kubernetes clusters.
• Provides external IP address allocation for Kubernetes LoadBalancer services.
• Supports both Layer 2 (ARP/NDP) and BGP-based network advertisement modes.
• Integrates seamlessly with Kubernetes networking and service management.
• Highly scalable and suitable for on-premises and private cloud deployments.

MetalLB Usage:

$ sudo su
$ apt update
$ Verify installtion: kubectl get deployment controller -n metallb-system -o jsonpath='{.spec.template.spec.containers[0].image}' 
echo

  

Disclaimer: MetalLB is provided as an open-source load-balancing solution for Kubernetes environments and is intended for use in bare-metal, on-premises, and self-managed clusters. Proper network configuration, IP address pool planning, and Kubernetes setup are required for successful operation. Users are responsible for securing their deployments, validating network compatibility, monitoring service availability, and maintaining updates before using MetalLB in production environments.
