Extensions Repository - Changes Summary

Date: 2025-12-11 Location: provisioning/extensions/ Status: Changes integrated into main provisioning repository

Overview

The extensions directory contains provider-specific implementations, task services, and cluster definitions. Current structure:

provisioning/extensions/
├── providers/          # Cloud provider implementations
├── taskservs/         # Infrastructure task services
├── clusters/          # Multi-node cluster definitions
└── config/            # Extension configuration

Current Structure & Components

1. 📦 Providers

Cloud provider implementations for infrastructure automation:

providers/
├── upcloud/           # UpCloud provider implementation
├── aws/               # Amazon AWS provider implementation
├── local/             # Local/on-premise provider
└── templates/         # Provider templates (Jinja2 .j2 files)

Changes: Configuration updates for provider detection and initialization.

2. 🔧 Task Services (Taskservs)

3. 🎯 Clusters

Multi-node cluster topology definitions:

clusters/
├── kubernetes-ha/     # High-availability Kubernetes
├── kubernetes-single/ # Single-node Kubernetes
├── etcd-cluster/      # etcd cluster
├── containerd-test/   # Containerd test setup
└── more...            # Additional cluster types

Changes: Nickel schema updates for cluster configuration.

4. ⚙️ Extension Configuration

Configuration for extension system:

config/
├── extensions.ncl     # Extension schema definitions
├── provider-registry.toml
├── taskserv-registry.toml
├── cluster-registry.toml
└── templates/         # Configuration templates

Key Architectural Points

Multi-Cloud Support

✅ Provider-agnostic batch operations ✅ Mixed provider workflows (UpCloud + AWS + local) ✅ Provider auto-detection and initialization

Taskserv System

✅ Self-contained, reusable task services ✅ Dependency resolution and ordering ✅ Auto-install with MCP integration ✅ Dynamic discovery and loading

Cluster Management

✅ Topology templates for common scenarios ✅ Multi-node cluster definitions ✅ HA configuration support ✅ Test environment integration

Integration with Core System

Nickel Schema Integration

let provisioning_extensions = import "provisioning/extensions.ncl" in

# Providers are loaded dynamically
let providers = provisioning_extensions.load_providers() in

# Taskservs are discovered and registered
let taskservs = provisioning_extensions.discover_taskservs() in

# Cluster definitions are templated
let clusters = provisioning_extensions.load_cluster_templates() in
{providers = providers, taskservs = taskservs, clusters = clusters}

REST API Integration

• GET /extensions/providers - List available providers
• GET /extensions/taskservs - List available taskservs
• POST /extensions/taskservs/install - Install taskserv
• GET /extensions/clusters - List cluster templates

CLI Integration

# Provider operations
provisioning providers list
provisioning providers validate

# Taskserv operations
provisioning taskserv create kubernetes --infra my-project
provisioning taskserv list

# Cluster operations
provisioning cluster create kubernetes-ha --infra my-project
provisioning cluster list

Configuration-Driven Design

All extensions are configuration-driven with no hardcoded values:

Provider Configuration (TOML)

[providers.upcloud]
endpoint = "https://api.upcloud.com"
auth_type = "bearer_token"
regions = ["de-fra1", "us-nyc1", "sg-sin1"]

[providers.aws]
endpoint = "https://ec2.amazonaws.com"
auth_type = "iam_role"
regions = ["us-east-1", "eu-west-1", "ap-southeast-1"]

Taskserv Configuration (Nickel)

let taskserv_definition = {
  name | string,
  version | string,
  provider | string,
  dependencies | [string],
  config | {},
  _check = [
    (std.string.length name > 0) || std.error "Name required",
    (std.string.length version > 0) || std.error "Version required",
  ]
} in taskserv_definition

Cluster Topology (Nickel/YAML)

let cluster_topology = {
  name | string,
  type | string,
  nodes | [{}],
  networking | {}
} in cluster_topology

Performance Characteristics

Provider Operations

• Auto-detection: <500ms
• Connection validation: <200ms per provider
• Region enumeration: <300ms

Taskserv Operations

• Discovery: <100ms
• Installation: varies by taskserv (10s - 5min)
• Self-installation: automatic dependency resolution

Cluster Operations

• Template loading: <50ms
• Multi-node validation: <300ms
• Topology generation: <500ms

Security Considerations

Provider Credentials

✅ Stored in KMS (Age, Vault, RustyVault, AWS KMS) ✅ Never in plaintext configs ✅ Rotated automatically via secrets system ✅ Audit logged for all access

Taskserv Isolation

✅ Container-based execution ✅ Network isolation per test environment ✅ Resource limits enforced ✅ No privilege escalation

Access Control

✅ Role-based access per provider ✅ Cedar policy enforcement ✅ MFA required for sensitive operations ✅ Audit trail for all changes

Extending the System

Adding a New Provider

1. Create provisioning/extensions/providers/{provider_name}/
2. Implement provider interface (Nushell module)
3. Add configuration in provisioning/config/extensions/{provider_name}.toml
4. Register in provider-registry.toml
5. Add Nickel schema in provisioning/schemas/extensions.ncl

Adding a New Taskserv

1. Create provisioning/extensions/taskservs/{taskserv_name}/
2. Implement installation script (Nushell)
3. Add configuration template (Jinja2 .j2)
4. Register in taskserv-registry.toml
5. Add Nickel schema with validation

Adding a New Cluster Type

1. Create provisioning/extensions/clusters/{cluster_name}/
2. Define cluster topology (Nickel/YAML)
3. Add node templates
4. Register in cluster-registry.toml
5. Add documentation with examples

Backward Compatibility

✅ All existing provider configurations continue to work ✅ New configuration format is optional (gradual migration) ✅ Legacy ENV variables supported with deprecation warnings ✅ Fallback mechanisms for missing configurations

Next Steps for Extensions

1. ✅ Unified architecture documentation
2. ✅ Complete API reference
3. ⏳ Additional provider implementations
4. ⏳ More cluster topology templates
5. ⏳ Performance optimization for large deployments
