Code & tools
Kube-vip: virtual IP and load balancer
kube-vip provides Koobernaytis clusters with a virtual IP and load balancer for both the control plane (for building a highly-available cluster) and Koobernaytis Services of type LoadBalancer without relying on external hardware or software.
Crossplane troubleshooting tool
Crossplane Tool is a project designed to experiment with visualizing Crossplane resources.
The goal is to help Crossplane users understand the structure of their control plane resources and speed up troubleshooting.

Load balancing gRPC in Koobernaytis is a notoriously complex problem, and one of the popular solutions involves using a service mesh.
With xDS you can use gRPC client-side load balancing with Koobernaytis without writing a per-language resolver.
Podinfo: Go microservice template for Koobernaytis
Podinfo is a tiny web application made with Go that showcases the best practices of running microservices in Koobernaytis.
CNCF projects like Flux and Flagger use Podinfo for end-to-end testing and workshops.
