* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones

# 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 [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 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.
