GKE Enterprise Multi-Tenancy Framework\n\nThis repository implements a controller framework for managing multi-tenant Kubernetes controllers in GKE Enterprise.\n\n## Overview\n\nThe core of this project is a \"meta-controller\" or **Manager** that dynamically starts and stops sets of controllers for each tenant. Tenants are defined by `ProviderConfig` resources. This approach ensures strict isolation and lifecycle management for tenant-specific logic.\n\n## Architecture\n\n### ProviderConfig\nThe `ProviderConfig` Custom Resource Definition (CRD) acts as the source of truth for a tenant's configuration. It controls the lifecycle of tenant-specific controllers.\n\n### Framework Manager\nThe Manager (`pkg/framework/manager.go`) watches `ProviderConfig` objects.\n- **On Add/Update**: It spins up a new set of controllers (e.g., NodeController, IPAMController) dedicated to that tenant.\n- **On Delete**: It ensures all tenant-specific controllers are stopped and cleans up resources (via Finalizers) before allowing the `ProviderConfig` to be deleted.\n- **Idempotency**: The manager ensures that repeated events do not trigger duplicate controller startups.\n\n### Isolation\nControllers are \"scoped\" to their tenant to ensure they only process resources (like Nodes) belonging to that tenant. This is achieved through:\n- **Filtered Informers**: Ensuring controllers only see objects matching specific labels or fields.\n- **Scoped Clients**: Restricting API access where possible.\n\n## Directory Structure\n\n| Directory | Description |\n|-----------|-------------|\n| `apis/` | Kubernetes API definitions (CRDs), specifically `ProviderConfig`. |\n| `pkg/framework/` | Core logic for the controller manager and lifecycle coordination. |\n| `pkg/providerconfig/` | Client sets, listers, and informers for the custom resources. |\n| `pkg/utils/` | Shared utilities for workqueues and common patterns. |\n| `pkg/finalizer/` | Helper logic for managing Kubernetes finalizers. |\n\n## Development\n\n### Prerequisites\n- Go 1.25.5+\n- Kubernetes environment (or test setup)\n\n### Build\nTo build the project:\n```bash\nmake build\n```\n\n### Test\nTo run unit and race detection tests:\n```bash\nmake test\n```\n\n### Utilities\n- `make fmt`: Format code\n- `make tidy`: Tidy Go modules\n- `make vet`: Run `go vet`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgooglecloudplatform%2Fgke-enterprise-mt","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgooglecloudplatform%2Fgke-enterprise-mt","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgooglecloudplatform%2Fgke-enterprise-mt/lists"}
