Metallb

Prerequisites — A local kubernetes cluster. — Access to your router’s control panel — An External Domain Name. If you don’t have one you can usually get one for $1 for your first year from ionos.com. …

In the previous article, we had set up a 3-node Kubernetes Cluster and deployed a .Net Core C# micro-front end and backend OpenAPI service into a single Pod on Kubernetes Cluster. We then exposed the App as a service with NodePort Type, accessible on individual nodes on the dynamic ports…

This guide aims at introducing us to “MetalLB” and showing how we can expose services within it in an on-premise environment — What is MetalLB? MetalLB is a load-balancer implementation for bare metal Kubernetes clusters that uses standard routing protocols. While you use Metallb you can specify load balancer IP addresses for services that need to be exposed outside of Kubernetes clusters. Why to use MetalLB?

Set up a MetalLB Load Balancer on a on-premises Kubernetes Cluster Introduction ❗️ Updated for MetalLB v0.13.7 💥 Kubernetes offers the following service types: ClusterIP: provides a load-balanced IP address for one or more pods that match a label selector and forwards requests to this IP address. Consequently that is a…

As all TFTP clients are external to Kubernetes, we used the NodePort service to expose TFTP server pod. The other way to expose the TFTP server to external clients is using service of type=LoadBalancer. Typically, cloud provider provisions a load-balancer and assigns it an IP address to be used by…

Jeganathan Swaminathan ( jegan@tektutor.org ) — In a bare-metal OpenShift setup, the LoadBalancer Service will not work by default, unlike the AWS ROSA or Azure RedHat OpenShift. This article assumes you already have a working RedHat OpenShift v4.x cluster. I used RedHat OpenShift v4.10.5. My local RedHat OpenShift cluster looks as shown below dispenser(jegan@tektutor.org)$ oc version Client…

This article was inspired from this blog post. Introduction Deploying a Kubernetes service of type load balancer in a public cloud environment is very simple. …

Jeganathan Swaminathan ( jegan@tektutor.org ) This article assumes, you already have a working Kubernetes Cluster setup locally either on your Laptop/Desktop/Workstation/Server. If you want to setup a Kubernetes cluster locally, check my article here https://medium.com/@jegan_50867/kubernetes-3-node-cluster-setup-50943378be41. I have my 3 node K8s cluster up and running [jegan@master.tektutor.org ~]$ kubectl get nodes NAME…

In a previous story I explained how to run a Kubernetes cluster locally with Kind, Cilium, and without kube-proxy. Kind cluster with Cilium and no kube-proxy Kind overviewmedium.com In this article I will show you how to add MetalLB into the mix to enable services of type LoadBalancer to work in your local cluster. MetalLB overview MetalLB is a load balancer…
