# CAST AI Local Dev Loop ## Overview Fast iteration workflow for CAST AI integrations: test autoscaler policies in a dev cluster, validate Terraform modules before applying to production, and use the CAST AI API to measure savings impact during development. ## Prerequisites - Completed `castai-install-auth` setup - A development Kubernetes cluster (kind, minikube, or cloud dev cluster) - `kubectl`, `helm`, and optionally `terraform` installed ## Instructions ### Step 1: Project Structure ``` my-castai-infra/ ├── terraform/ │ ├── environments/ │ │ ├── dev.tfvars │ │ ├── staging.tfvars │ │ └── prod.tfvars │ ├── modules/ │ │ └── castai-cluster/ │ │ ├── main.tf │ │ ├── variables.tf │ │ └── outputs.tf │ └── main.tf ├── policies/ │ ├── dev-policy.json │ └── prod-policy.json ├── scripts/ │ ├── check-savings.sh │ └── validate-policies.sh ├── .env.dev # Dev API key (git-ignored) └── .env.example ``` ### Step 2: Dev Cluster with Relaxed Policies ```bash # Connect your dev cluster (read-only first) helm upgrade --install castai-agent castai-helm/castai-agent \ -n castai-agent --create-namespace \ --set apiKey="${CASTAI_API_KEY_DEV}" \ --set provider="eks" # Apply development-safe autoscaler policy curl -X PUT -H "X-API-Key: ${CASTAI_API_KEY_DEV}" \ -H "Content-Type: application/json" \ "https://api.cast.ai/v1/kubernetes/clusters/${CASTAI_CLUSTER_ID}/policies" \ -d '{ "enabled": true, "unschedu...
