Metallb Alternatives

Reviews and mentions

• Port management in your local Kubernetes cluster

  My latest attempt was MetalLB. Even though I didn't manage to make it work, it bound port 8080 on my machine: none of my other regular Spring demos could work.

• Pi k8s! This is my pi4-8gb powered hosted platform. 8 pi4s for kubeadm k8s cluster, and one for a not so 'nas' share. I use gitlab runners with helmfile to manage my applications. Running over a year and finally passed the CKA with most of my practice on this plus work clusters. AMA welcome!

  I use metalLB as my load balancer because it is software based and any of the nodes can respond to the ip related to the deployment. https://metallb.universe.tf/

  If you just need balacing k3s services like controle-plane or ingresses you can use kube-vip with metallb.

  Regarding the service type `LoadBalancer`: The k8s service type `LoadBalancer` is a derivation resource of an external loadbalancer. For managed k8s services, if you create a new service with type `LoadBalancer` a external loadbalancer will be created. The pods that are matching the label selector of the service can then be accessed with the external IP of the LoadBalancer. If you want to setup loadbalancing manually using HAProxy, you can probably deploy the ingress controller with service type `NodePort` instead of `LoadBalancer`. But you could also just deploy MetalLB in your cluster (Read the "Why?" section).

  Have a look at MetalLB, it's quite easy to setup (don't forget to generate a secret for it when you deploy it: kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)" - :')) and to use (just use add in your services' spec type: LoadBalancer and you can specify an IP in the range(s) you configured in metalLB's configmap with loadBalancerIP: 1.2.3.4, here's a small example (with a wireguard UDP service, listening on 172.20.2.203:51820):

  https://metallb.universe.tf is an option

  metalLB to manage bare-metal LoadBalancer services - WIP - Only L2 configuration can be set-up via playbook.

• F5 Load Balancing / WAF alternatives
  1 project | reddit.com/r/networking | 27 Jul 2021

  Have you checked out MetalLB (https://metallb.universe.tf/)? We use it in BGP configuration for Ingress traffic and have no issues with it so far. The same would be achievable with different network plugins (e.g. Calico: https://docs.projectcalico.org/networking/bgp). We have actively decided against an external L5 LB after prolonged planning, as a seamless integration into the kubernetes context was not readily possible. As WAF we use (already provided by the nginx ingress controller) ModSecurity.

• Kube on-prem control plane NLB setup?
  2 projects | reddit.com/r/kubernetes | 24 Jul 2021

  I'm using https://metallb.universe.tf/ on my home cluster. Each service with type=LoadBalancer gets it's own virtual IP. However it doesn't round-robin and will send traffic to 1 pod.

  I've got MetalLB setup and a CIDR range I've blocked off on my router. This gives me a few LoadBalancers with Layer2 Mode and my ingresses can piggy back off of that. I think, under the hood, that MetalLB uses NodePorts to manage the connections to each of the pods and keeps a running table of them in etcd via the K8s API.

• Kubernetes at home switch advice
  1 project | reddit.com/r/homelab | 29 Jun 2021

  Networking on bare metal Kubernetes can be done using Node Ports, Host mode for your pods, or load balancing using MetalLB in Layer 2 mode, none of which even require a managed switch. Personally I have a Cisco switch that talks BGP to MetalLB running in BGP mode on my bare metal cluster, works fine, but I've used Layer 2 mode before without a fancy switch and it worked just fine.

• Confused about Load Balancing/Ingress on VM based, HA setup
  2 projects | reddit.com/r/kubernetes | 13 Jun 2021

  We need to take care of HA, service Load Balancing, cert management, security, backups, monitoring, logging, a CNI suitable for our needs of course and so on. And then you have the "beta" disclaimer (for example for MetalLB) so how do you find something that you can be confident that will work in production and that you'll get support for? That's why I am beginning to think that doing everything from scratch and especially when we're talking about production clusters, may not be realistic at some point.

• Kubernetes, external-dns, Pi-hole and a custom domain
  8 projects | dev.to | 8 May 2021

  Now the only thing we've to do is to kubectl apply these files, and we'll end up with a working CoreDNS instance. Working but still not reachable outside the cluster, if you have MetalLB configured, you can change the ServiceType from ClusterIP to LoadBalancer to get an IP. I haven't this feature in my cluster yet, so for now, I'm going to use the NodePort type; this allows me to use a port of my node and point it to the service.
