Generally speaking, MetalLB doesn’t care which network addon you choose to run in your cluster, as long as it provides the standard behaviors that Kubernetes expects from network addons.
The following is a list of network addons that have been tested with MetalLB, for your reference. The list is presented in alphabetical order, we express no preference for one addon over another.
Addons that are not on this list probably work, we just haven’t tested them. Please send us a patch if you have information on network addons that aren’t listed!
|Calico||Partial (see known issues)|
|Kube-router||No (work in progress)|
|Romana||Yes (see guide for advanced integration)|

MetalLB is currently not compatible with IPVS mode in kube-proxy,
due to several outstanding bugs with IPVS mode’s handling of
LoadBalancer services. See
