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](https://metallb.universe.tf/concepts/layer2/).
It deploys MetalLB into Kubernetes and sets up a layer 2 load-balancer.
This addon aims to automate [MetalLB in layer 2 mode](https://metallb.universe.tf/concepts/layer2/)
or [MetalLB in BGP mode][https://metallb.universe.tf/concepts/bgp/].
It deploys MetalLB into Kubernetes and sets up a layer 2 or BGP 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`.
You can override the defaults by copying the contents of roles/kubernetes-apps/metallb/defaults/main.yml
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.
