GitOps to Automate the Setup, Management and Extension a K8s Cluster
summary
Uses Terraform to provision a DigitalOcean managed Kubernetes cluster called kubecon-cluster, bootstraps Flux CD which creates a GitHub repo (kubecon-workshop) and reconciles manifests, installs sealed-secrets and uses kubeseal to produce an encrypted SealedSecret that decrypts inside the cluster, and adds the Crossplane DigitalOcean provider to create a separate Droplet from within Kubernetes. Demos mostly succeed (cluster, GitOps sync, secret round‑trip, droplet creation); a few manual steps appear (port‑forward for the cert, manual droplet cleanup due to a provider issue).
