Deploy MetalLB into Kubespray/Kubernetes

MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type "LoadBalancer" in clusters that don't run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers. This addon aims to automate this. It deploys MetalLB into Kubernetes and sets up a layer 2 load-balancer.

Install

In the default, MetalLB is not deployed into your Kubernetes cluster. You can override the defaults by copying the contents of this file to somewhere in inventory/mycluster/group_vars such as inventory/mycluster/groups_vars/k8s-cluster/addons.yml and updating metallb_enabled option to true. In addition you need to update metallb_ip_range option on the addons.yml at least for suiting your network environment, because MetalLB allocates external IP addresses from this metallb_ip_range option.
