These examples demonstrate how to onboard your cluster to CAST AI using a GitOps approach. In these scenarios, CAST AI Node Configuration, Node Templates, and Autoscaler policies are managed using Terraform. However, you can install other components such as:

castai-agent
castai-cluster-controller
castai-evictor
castai-spot-handler
castai-kvisor

using alternative tools like ArgoCD, manual Helm releases, or other preferred methods.
