Sveltos Templating: Cilium Cluster Mesh

Introduction​

Have you ever wondered how to dynamically instantiate Kubernetes resources before deploying them to a cluster? What if I tell you there is an easy way to do it? Sveltos lets you define add-ons and applications using templates. Before deploying any resource down the managed clusters, Sveltos instantiates the templates using information gathered from the management cluster.

In a previous post, we outlined a step-by-step approach to forming a Cilium cluster mesh between two clusters. In today's post, we will demonstrate how the Sveltos templating is used to deploy a Cilium cluster mesh dynamically in one go.

Introduction​

For the last couple of days, I have been working on a new use case installing RKE2 clusters powered with Cilium by Azure Cloud. The requirement at hand was to use a Rancher instance and from there start deploying RKE2 clusters. I found that the official Rancher documentation has outdated instructions for pre-configuring Azure Cloud.

In today's blog post, we will outline the steps to set up Azure cloud-free credits for deploying RKE2 clusters with Cilium. Additionally, we will cover any limitations that come with the free credit concept.

Introduction​

Working with on-prem RKE2 clusters, I noticed many issues in forming a Cilium cluster mesh between clusters in an automated way.

In this post, I will walk through a step-by-step process to get a Cilium cluster mesh up and running. We will cover the problems I ran into along the way. The goal is to follow a GitOps-friendly approach, with no need for the Cilium CLI. We will use Helm and kubectl for the setup.

Introduction​

In today's blog post, we will demonstrate an easy way of deploying and controlling Cilium on an EKS cluster with Sveltos.

Most documentation shows step-by-step installation using Helm chart commands. So, we chose to show a different way: the GitOps approach. We will use the Sveltos ClusterProfile CRD (Custom Resource Definition) for this.
