If you are not installing MetalLB via the separate public and private interfaces. However, I have a nice Ubiqitui USG Router that does all sorts of nice stuff like iBGP, and I wanted to use that to be able to advertise an entirely different address space exclusively for the use of k8s LoadBalancer Services.

Using this method will ensure consistency of configuration parameters without the need to maintain persistent volumes, with the added benefit of residing within the etcd database and is therefore included in etcd backups. installation, you must first uninstall the manifest-based version, Now lets make sure we have a Service of type LoadBalancer, and then request an IP in the newly defined range, by editing an existing Service to add: If you ask k8s for the Service info (kubectl get svc kubernetes-dashboard) you’ll see we got the IP we requested: We can also check on the BGP peering session from the router: We have 1 prefix of size /32 (e.g.

And apply that ConfigMap with our regular methods (kubectl apply -f ...). should reduce the amount of visual noise in the logs. In a recent post, I detailed how to use Layer2 advertisements with MetalLB to simulate internal LoadBalancers for Kubernetes. Baremetal will require persistent storage to be setup and it's recommended to use metalLB for loadbalancer creation.
The following four commands set each of the Kubernetes worker nodes to be a neighbor to the router. If you do this, you can check the routes with this command: For me, it returns the following table showing that I have four services using load balancing: The service at service IP 192.168.1.225 is replicated on two nodes (192.168.1.203 and 192.168.1.201) and the service at 192.168.1.226 is replicated on three nodes (192.168.1.205, 192.168.1.202, and 192.168.1.201).
