description: Prior to v0.13, MetalLB was configured using a ConfigMap. This has all changed now, and CRDs are required to perform configuration (which improves syntax checking, abong other things)

# Updated MetalLB recipe for CRDs
|
|
|
|
Prior to v0.13, [MetalLB][metallb] was configured using a ConfigMap. This has all changed now, and CRDs are required to perform configuration (which improves syntax checking, abong other things)

|
[MetalLB](https://metallb.universe.tf/) offers a network [load balancer](/kubernetes/loadbalancer/) implementation which workes on "bare metal" (*as opposed to a cloud provider*).
|
|
|
|
MetalLB does two jobs:
|
|
|
|
1. Provides address allocation to services out of a pool of addresses which you define
|
|
2. Announces these addresses to devices outside the cluster, either using ARP/NDP (L2) or BGP (L3)
