Sveltos Templating: Cilium Cluster Mesh in One Run

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 on Azure Cloud. The requirement at hand was to use a Rancher instance and from there start deploying RKE2 clusters. After going through the official Rancher documentation, I have noticed that the instructions provided to pre-configure Azure Cloud are outdated.

In today's blog post, we will cover all the required steps taken to configure the Azure cloud-free credits to deploy RKE2 clusters with Cilium in that environment. Additionally, we will cover any limitations that come with the free credit concept.

Introduction​

After spending some time working with the on-prem RKE2 lab setup, I came to notice a couple of issues while forming in an automated fashion the Cilium cluster mesh between on-prem clusters.

In today's post, we will go through the step-by-step process of forming a Cilium Cluster Mesh and explain any issues that might have arisen by following the GitOps approach. The cilium CLI will not be required. The deployment will be performed primarily via Helm and kubectl.

Introduction​

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

As the majority of the documentation out there provides a step-by-step installation directly with the Helm chart commands, we decided to demonstrate a different approach, the GitOps approach, with the use of Sveltos ClusterProfile CRD (Custom Resource Definition).
