It provisions and lifecycle-manages storage, databases, search, streaming, and analytics backends as first-class Kubernetes resources (`DataResource` CRs), on behalf of isolated tenants.\n\n**Module:** `github.com/penguintechinc/nest`  \n**API base:** `/api/v1`\n\n## What Nest Manages\n\nBlock volumes, shared filesystems, S3-compatible object buckets, PostgreSQL clusters, Valkey/Redis, Kafka, OpenSearch (dedicated and shared multi-tenant), ClickHouse, Trino, Iceberg, vector databases, NFS, iSCSI — and cloud-native equivalents (EBS, GCS, Azure Blob, etc.).\n\nAll resources are provisioned through a single `DataResource` CR and managed by the Nest k8s-controller. Rook-Ceph provides the on-cluster storage backend. Cloud-native block and object storage (AWS EBS/S3, Azure Disk/Blob, GCP PD/GCS) is available via 3rd-party management mode.\n\n## Management Modes\n\nNest operates in two modes, selectable per `DataResource` via `spec.origination`:\n\n**1st Party — Managed** (`origination: managed`, default)  \nNest provisions and fully lifecycle-manages the resource on-cluster using Rook-Ceph (block, file, object), CNPG (PostgreSQL), OpenSearch, Valkey, and other operators. Full feature support: data protection, PITR, DarkDrive-aware scheduling, CSI, Eggs, anomaly detection.\n\n**3rd Party — Cloud-Native** (`origination: external`)  \nNest provisions and manages cloud-provider resources via their native APIs — AWS EBS/S3, Azure Managed Disk/Blob, GCP Persistent Disk/GCS. DataResource lifecycle (create/delete/status), tenant isolation, quota, and audit are fully supported. Some features are unavailable or provider-dependent. See [docs/spec/provider-support.md](docs/spec/provider-support.md) for the feature matrix.\n\n**Imported** (`origination: imported`)  \nNest registers and monitors an existing external resource (e.g. an existing RDS instance) without provisioning it. Supports introspection and health probing only.\n\n## Quick Start\n\n```bash\n# Deploy Nest\nkubectl kustomize k8s/kustomize/overlays/alpha | kubectl apply -f -\n\n# Provision a block volume\nkubectl apply -f - \u003c\u003cEOF\napiVersion: nest.penguintech.io/v1\nkind: DataResource\nmetadata:\n  name: my-volume\n  namespace: default\nspec:\n  type: pvc/block\n  tenant: acme\n  size:\n    storage: 20Gi\nEOF\n\nkubectl wait --for=condition=Ready dataresource/my-volume --timeout=120s\n```\n\n## Documentation\n\n| Document | Description |\n|---|---|\n| [docs/USAGE.md](docs/USAGE.md) | Full user guide — all DataResource types, data protection, eggs, tenant isolation, API reference |\n| [docs/spec/storage-types.md](docs/spec/storage-types.md) | Exhaustive type reference with YAML examples for every supported backend |\n| [docs/WORKFLOWS.md](docs/WORKFLOWS.md) | Lifecycle workflows — provisioning, protection, migration, restore, onboarding |\n| [docs/CONTRIBUTING.md](docs/CONTRIBUTING.md) | Development setup, adding new types, PR process |\n| [docs/migration/longhorn-to-nest.md](docs/migration/longhorn-to-nest.md) | Migration guide from Longhorn |\n| [docs/ops/migrate-from-longhorn.md](docs/ops/migrate-from-longhorn.md) | Ops runbook for Longhorn migration |\n| [docs/ops/object-storage-lifecycle.md](docs/ops/object-storage-lifecycle.md) | Object storage operations |\n| [docs/infrastructure/ceph-architecture.md](docs/infrastructure/ceph-architecture.md) | Rook-Ceph integration architecture |\n| [docs/infrastructure/ceph-deployment.md](docs/infrastructure/ceph-deployment.md) | Ceph + Nest deployment guide |\n| [docs/infrastructure/ceph-troubleshooting.md](docs/infrastructure/ceph-troubleshooting.md) | Troubleshooting Ceph, CSI, and storage issues |\n\n## Architecture\n\n```\n                    ┌─────────────────────────────────┐\n                    │         Kubernetes API           │\n                    └───────────────┬─────────────────┘\n                                    │ DataResource CRs\n                    ┌───────────────▼─────────────────┐\n                    │        k8s-controller            │\n                    │  (reconciles all DataResource    │\n                    │   types + DataProtectionPolicy)  │\n                    └──┬───────┬───────┬───────┬──────┘\n                       │       │       │       │\n              ┌────────▼─┐ ┌───▼──┐ ┌──▼───┐ ┌▼────────┐\n              │ Rook-Ceph│ │ CNPG │ │Valkey│ │OpenSearch│\n              │(RBD/CephFS│ │ (PG) │ │/Redis│ │Operator │\n              │   /RGW)  │ └──────┘ └──────┘ └─────────┘\n              └──────────┘\n\n  node-agent (DaemonSet) → discovers DarkDrives → HardwareInventory CRs\n  CSI driver             → thin shim proxying to Rook-Ceph sockets\n  injector               → MutatingWebhook rewrites nest-block → rook-ceph-block\n  scheduler              → places DataResources on pools with DarkDrives preferred\n  nest-api (Python/Quart)→ REST API for tenant operations\n  admin-ui (React)       → web dashboard\n```\n\n## License\n\nSee [docs/LICENSE.md](docs/LICENSE.md).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpenguintechinc%2Fnest","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpenguintechinc%2Fnest","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpenguintechinc%2Fnest/lists"}
