Description

Metallb is a popular load balancer for bare metal Kubernetes clusters. It is an open source software that provides a network load-balancing layer to Kubernetes. With Metallb, you can use standard Kubernetes Service objects to represent external load-balancers and make Kubernetes services accessible from outside the cluster. It supports a range of load-balancing algorithms, including layer 2, layer 4, and BGP routing, making it a versatile choice for various network architectures.

  • Supports Layer 2 (Data Link Layer) and Layer 4 (Transport Layer) load balancing.
  • Can integrate with standard network equipment, such as routers and switches, to distribute traffic to worker nodes.
  • Provides a range of load-balancing algorithms, including round-robin, least connections, and IP hash.
  • Supports both TCP and UDP traffic.
  • Can be configured to automatically assign IP addresses to services, eliminating the need for manual IP allocation.

  • MetalLB is a great solution for companies looking to deploy a Kubernetes cluster on their own hardware, without relying on a cloud provider's load balancer service. It provides an easy way to add load balancing functionality to bare-metal clusters, enabling companies to distribute network traffic across multiple nodes.
  • MetalLB can also be used in situations where an organization wants to keep their Kubernetes cluster private and isolated, without exposing it to the public internet. With MetalLB, companies can create an internal load balancer to distribute traffic within the cluster.

  1. Install the MetalLB software on their Kubernetes cluster.
  2. Configure the load-balancer by specifying the IP address range to be used, the load-balancing algorithm to be used, and any network-specific settings.
  3. Create a Kubernetes service to use the MetalLB load balancer, specifying the type of load balancing required.
  4. Start using the service.

  • MetalLB uses standard network protocols, such as ARP and DHCP, to route traffic to worker nodes.
  • MetalLB is designed to work with standard network equipment, such as routers and switches, allowing companies to leverage existing hardware investments.
  • MetalLB is deployed as a Kubernetes pod, providing an easy way to manage the load balancer using standard Kubernetes tools.
  • MetalLB supports a range of load-balancing algorithms, including layer 2, layer 4, and BGP
