sveltosctl VS addon-controller

Once the RKE2 cluster is in a “Running” state, we will use the sveltosctl to register it. For the registration, we need three things: a service account, a kubeconfig associated with that account and a namespace. If you are unsure how to create a Service Account and an associated kubeconfig, there is a script publicly available to help you out.

The Sveltosctl, is the command-line interface (CLI) for Sveltos. This is an available option to query Sveltos resources and it is available as a Kubernetes pod or as a binary.

sveltosctl can be used to display collected techsupports.

Using sveltosctl we can verify Sveltos is aware system-admin has full access to managed cluster with label env:production

But I was still not happy. Main reason, users still had to go and manage cluster labels. I wanted clusters' labels to change as cluster runtime state was changing. So I can express my intent and then forget about it.

So I introduced a second concept in Sveltos. Classifier CRD (https://github.com/projectsveltos/demos/blob/main/classifier...) which allows users to classify clusters based on cluster runtime state (currently kubernetes version and/or resources deployed, but I am working on adding more).

Doing so I can easily now say:

With projectsveltos, you can instruct add-on controller to deploy resources using Kustomize (on top of Helm charts and regular YAMLs). Then you could use its event-driven framework to deploy extra resources on demands.

When deploying add-ons with Sveltos Kuberntes add-on controller it is now possible to also enforce add-on constraints (defined in the management cluster using openapi).
