Top 3 Go add-on Projects

kube-fledged

10 1,204 4.7 Go

A kubernetes operator for creating and managing a cache of container images directly on the cluster worker nodes, so application pods start almost instantly

Exactly. Part of the appeal to consolidate all of our container images to use Debian-slim is the ability to optimise the caching of layers, both in our container registry but also on our kubernetes cluster’s nodes (which can be done in a consistent manner with kube-fledged[1]).

sveltosctl

5 18 8.1 Go

A CLI to nicely display resources/helm charts deployed in CAPI Cluster by Sveltos. Collect tech-support from managed Kubernetes clusters.

Project mention: 5-Step Approach: ProjectSveltos Event Framework for Kubernetes Deployment with Cilium Gateway API | dev.to | 2024-02-19

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.
