## 📖 Key Concepts
### App-of-Apps Pattern
`_app-of-apps.yaml` is the root Application that manages all other Applications in `infra/`. Kustomize overlays in `infra/overlays/{upc-dev,upc-prod}/` render the base Applications with per-cluster patches (e.g., swapping value file paths from `upc-dev` to `upc-prod`).
`_app-of-apps-{cluster}.yaml` is the root Application that manages all other Applications in `infra/`. Kustomize overlays in `infra/overlays/{cluster}/` render the base Applications with per-cluster patches (e.g., swapping value file paths). Supported clusters: `upc-dev`, `upc-prod`, `eks-dev`, `eks-prod`, `aks-dev`, `aks-prod`, `gke-dev`, `gke-prod`.
### Multi-Source Pattern

## 📝 Notes
### Current Environment
- **Provider**: UpCloud Managed Kubernetes
- **Provider**: Multi-cloud (UpCloud, AWS EKS, Azure AKS, GCP GKE)
- **Active clusters**: UpCloud (upc-dev, upc-prod)
- **Environment**: Production (internal use only)
- **Clusters**: Multi-cluster (upc-dev, upc-prod) via Kustomize overlays
- **Auth**: Disabled for ArgoCD (internal access)
- **Backup**: None (cluster rebuildable via GitOps)
- **Backup**: Gitea daily backup to S3-compatible storage
### Known Limitations
- No automated backups (yet)
- Secret rotation not automated
- Multi-cluster limited to upc-dev and upc-prod environments
- DNS management is manual
**Future improvements**: See [Operations Runbook - Disaster Recovery](docs/OPERATIONS-RUNBOOK.md#disaster-recovery)
