[jguionnet]

Summary by cubic

Adds a complete KubeCon NA 2025 demo with notebooks to set up k3d + Crossplane + KubeVela, contribute a simple DynamoDB OAM component, and clean up. Also adds a KubeVela power demo with a Flask Product Catalog app comparing traditional (Terraform + Kubernetes + GitHub Actions) vs KubeVela.

• New Features

  • Four notebooks: environment setup, OAM contribution (DynamoDB), OAM cleanup, and full teardown.
  • Centralized settings in config.yaml; supports Crossplane (Helm), KubeVela, k3d, and optional AWS provider.
  • KubeVela power demo (KV-demo) with app code, docs (DEMO_PLAN.md, COMPARISON.md), and a full traditional vs KubeVela comparison (Terraform, K8s manifests, GitHub Actions, Dagger, local deploy script).
  • README quick start, curated requirements.txt, demo-specific .gitignore; script to copy AWS credentials to dev/staging/prod namespaces.

• Migration

  • Replace “00 Setup.ipynb” with: 00_Env-setup → 01_OAM-contrib → 01-OAM-cleanup → 00-Env-cleanup.
  • Create .env.aws if using AWS; cleanup notebooks are destructive and remove the k3d cluster and demo resources.
