Add gitignore patterns for Lambda Labs cloud provider files:
- Dynamic Kconfig generation (*.generated)
- API credential files (.lambdalabs_*)
- Cloud configuration cache files
- SSH configuration files
These files are generated at runtime and should not be tracked.

Add core Python API library for Lambda Labs cloud provider integration:
- Low-level API access with Bearer token authentication
- Instance types discovery with capacity information
- Regions extraction from instance data
- Dynamic Kconfig generation for instance types and regions
- Pricing data integration
- Proper error handling and fallback mechanisms
This provides the foundation for Lambda Labs cloud provider support
in kdevops, enabling dynamic configuration based on real-time
availability and pricing data.

+.SH INTEGRATION WITH KDEVOPS
+.SS Makefile Integration
+The lambda-cli tool can be integrated into kdevops Makefiles:
+.PP
+.RS
+.nf
+LAMBDA_CLI := $(TOPDIR_PATH)/scripts/lambda-cli
+
+lambda-list-instances:
+ @$(LAMBDA_CLI) instance-types list --available-only
+
+lambda-smart-select:
+ @$(LAMBDA_CLI) smart-select --mode cheapest
+.fi
+.RE
+.SS Kconfig Integration
+Use lambda-cli in Kconfig shell commands:
+.PP
+.RS
+.nf
+config TERRAFORM_LAMBDALABS_REGION
+ string
+ default $(shell, scripts/lambda-cli smart-select \\
+ --mode cheapest -o json | \\
+ python3 -c "import sys, json; \\
+ print(json.load(sys.stdin).get('region'))")
+.fi
+.RE
+.SS Ansible Integration
+Call lambda-cli from Ansible playbooks:
+.PP
+.RS
+.nf
+- name: Get cheapest Lambda Labs instance
+ command: scripts/lambda-cli instance-types \\
+ get-cheapest --output json
+ register: cheapest_instance
+ delegate_to: localhost
+.fi
+.RE
+.SH EXIT STATUS
+.TP
+.B 0
+Successful execution
+.TP
+.B 1
+General error (invalid arguments, API failure, etc.)
+.SH DIAGNOSTICS
+The lambda-cli tool provides detailed error messages when operations fail.
+Common issues include:
+.TP
+.B "No API key found"
+Set LAMBDALABS_API_KEY environment variable or configure ~/.lambdalabs/credentials
+.TP
+.B "No available instances matching criteria"
+No instances have current capacity matching the specified filters
+.TP
+.B "API request failed"
+Network error or invalid API key
+.SH NOTES
+.SS Caching
+The underlying Lambda Labs API library may cache responses for performance.
+Cache duration is typically 15 minutes for pricing data.
+.SS Fallback Behavior
+When API access fails, lambda-cli will attempt to use sensible defaults:
+.RS
+.IP \(bu 2
+Default instance type: gpu_1x_a10
+.IP \(bu 2
+Default region: us-west-1
+.IP \(bu 2
+Static Kconfig with minimal options
+.RE
+.SS Rate Limiting
+Be aware of Lambda Labs API rate limits when using lambda-cli in automated
+scripts. Consider adding delays between requests in tight loops.

Add secure credential management for Lambda Labs API access:
- Support for environment variable (LAMBDALABS_API_KEY)
- Local credential file storage (~/.config/lambda-labs/credentials)
- API key validation and testing
- Secure file permissions (0600)
- Cross-platform compatibility
Provides standardized credential handling following cloud provider
best practices for API key management.

+# Dynamic Cloud Kconfig Generation
+
+This document describes how kdevops implements dynamic configuration generation for cloud providers, using Lambda Labs as the reference implementation. This approach can be adapted for other cloud providers.
+
+## Table of Contents
+
+1. [Overview](#overview)
+2. [Architecture](#architecture)
+3. [Lambda Labs Implementation](#lambda-labs-implementation)
+4. [Creating a New Cloud Provider](#creating-a-new-cloud-provider)
+5. [API Reference](#api-reference)
+
+## Overview
+
+Dynamic cloud Kconfig generation allows kdevops to query cloud provider APIs at configuration time to present users with:
+- Currently available instance types
+- Regions with capacity
+- Real-time pricing information
+- Smart selection of optimal configurations
+
+This eliminates hardcoded lists that become outdated and helps users make informed decisions based on current availability.
+

+
+### Data Flow
+
+1. **Configuration Time** (`make menuconfig`):
+ - Makefile detects cloud provider selection
+ - Triggers dynamic Kconfig generation
+ - CLI tool queries cloud API
+ - Generates `.generated` files
+ - Kconfig includes generated files
+
+2. **Runtime** (Terraform/Ansible):
+ - Uses values from `extra_vars.yaml`
+ - No API calls needed
+ - Configuration already resolved
+
+## Lambda Labs Implementation
+
+### 1. CLI Tool (scripts/lambda-cli)
+
+The `lambda-cli` tool provides a unified interface for all Lambda Labs operations:
+
+```bash
+# Generate Kconfig files
+lambda-cli generate-kconfig
+
+# Query available instances
+lambda-cli --output json instance-types list
+
+# Smart selection
+lambda-cli --output json smart-select --mode cheapest
+```
+
+**Key Features:**
+- Structured command interface (mimics AWS CLI)
+- JSON and human-readable output formats
+- Error handling with fallbacks
+- Caching for performance
+
+### 2. API Library (scripts/lambdalabs_api.py)
+
+Core API functionality:
+
+```python
+def get_instance_types_with_capacity(api_key: str) -> Tuple[Dict, Dict[str, List[str]]]:
+ """
+ Get instance types and their regional availability.
+ Returns: (instances_dict, capacity_map)
+ """
+ response = make_api_request("/instance-types", api_key)
+ # Process and return structured data
+```
+
+### 3. Kconfig Integration
+
+#### Static Kconfig (terraform/lambdalabs/kconfigs/Kconfig.location)
+
+```kconfig
+choice
+ prompt "Lambda Labs region selection method"
+ default TERRAFORM_LAMBDALABS_REGION_SMART_CHEAPEST
+
+config TERRAFORM_LAMBDALABS_REGION_SMART_CHEAPEST
+ bool "Smart selection - automatically select cheapest"
+ help
+ Uses lambda-cli to find the cheapest instance globally
+
+config TERRAFORM_LAMBDALABS_REGION_MANUAL
+ bool "Manual region selection"
+ help
+ Manually select from available regions
+
+endchoice
+
+# Include dynamically generated regions when manual selection
+if TERRAFORM_LAMBDALABS_REGION_MANUAL
+source "terraform/lambdalabs/kconfigs/Kconfig.location.generated"
+endif
+
+# Smart inference using lambda-cli
+config TERRAFORM_LAMBDALABS_REGION
+ string
+ output yaml
+ default $(shell, python3 scripts/lambdalabs_smart_inference.py region) if TERRAFORM_LAMBDALABS_REGION_SMART_CHEAPEST
+```
+
+#### Generated Kconfig (Kconfig.location.generated)
+
+```kconfig
+# Dynamically generated from Lambda Labs API
+# Generated at: 2025-08-27 12:00:00
+
+choice
+ prompt "Lambda Labs region"
+ default TERRAFORM_LAMBDALABS_REGION_US_WEST_1

+
+# ... more regions
+endchoice
+```
+
+### 4. Makefile Integration
+
+The `dynamic-cloud-kconfig.Makefile` handles generation:
+
+```makefile
+# Lambda Labs dynamic Kconfig generation
+terraform/lambdalabs/kconfigs/Kconfig.compute.generated: .config
+ @echo "Generating Lambda Labs compute Kconfig..."
+ @python3 scripts/lambda-cli --output json generate-kconfig \
+ --output-dir terraform/lambdalabs/kconfigs
+
+terraform/lambdalabs/kconfigs/Kconfig.location.generated: .config
+ @echo "Generating Lambda Labs location Kconfig..."
+ @python3 scripts/lambda-cli --output json generate-kconfig \
+ --output-dir terraform/lambdalabs/kconfigs
+
+# Include generated files as dependencies
+KCONFIG_DEPS += terraform/lambdalabs/kconfigs/Kconfig.compute.generated
+KCONFIG_DEPS += terraform/lambdalabs/kconfigs/Kconfig.location.generated
+```
+
+### 5. Smart Inference
+
+The system provides intelligent defaults through shell command execution in Kconfig:
+
+```kconfig
+config TERRAFORM_LAMBDALABS_INSTANCE_TYPE
+ string
+ output yaml
+ default $(shell, python3 scripts/lambdalabs_smart_inference.py instance)
+```
+
+The `lambdalabs_smart_inference.py` wrapper calls lambda-cli:
+
+```python
+def get_smart_selection():
+ """Get smart selection from lambda-cli"""
+ result = subprocess.run(
+ ['scripts/lambda-cli', '--output', 'json',
+ 'smart-select', '--mode', 'cheapest'],
+ capture_output=True
+ )
+ return json.loads(result.stdout)
+```
+
+## Creating a New Cloud Provider
+
+To add dynamic Kconfig support for a new cloud provider, follow this pattern:
+
+### Step 1: Create the CLI Tool
+
+Create `scripts/provider-cli`:
+
+```python
+#!/usr/bin/env python3
+"""CLI tool for Provider cloud management."""
+
+import argparse
+import json
+from provider_api import get_instances, get_regions
+
+class ProviderCLI:
+ def list_instance_types(self):
+ # Query API and return structured data
+ pass
+
+ def generate_kconfig(self, output_dir):
+ # Generate Kconfig files
+ pass
+
+def main():
+ parser = argparse.ArgumentParser()
+ # Add commands and options
+ # Handle commands
+```
+
+### Step 2: Create API Library
+
+Create `scripts/provider_api.py`:
+
+```python
+def get_instance_types():
+ """Get available instance types from provider."""
+ # API communication
+ # Data transformation
+ return instances
+
+def generate_instance_kconfig(instances):
+ """Generate Kconfig choices for instances."""
+ kconfig = "choice\n"
+ kconfig += ' prompt "Instance type"\n'
+ for instance in instances:
+ kconfig += f"config PROVIDER_INSTANCE_{instance['id']}\n"
+ kconfig += f' bool "{instance["name"]}"\n'
+ kconfig += "endchoice\n"
+ return kconfig
+```
+
+### Step 3: Create Kconfig Structure
+
+```
+terraform/provider/kconfigs/
+├── Kconfig.compute # Static configuration
+├── Kconfig.location # Static configuration
+└── Kconfig.smart # Smart defaults
+```
+
+### Step 4: Add Makefile Rules
+
+In `scripts/dynamic-cloud-kconfig.Makefile`:
+
+```makefile
+ifdef CONFIG_TERRAFORM_PROVIDER
+terraform/provider/kconfigs/Kconfig.%.generated:
+ @python3 scripts/provider-cli generate-kconfig
+endif
+```
+
+### Step 5: Integration Points
+
+1. **Credentials Management**: Create `provider_credentials.py`
+2. **Smart Inference**: Create wrapper scripts for Kconfig shell commands
+3. **Terraform Integration**: Add provider configuration
+4. **Ansible Integration**: Add provisioning support
+
+## API Reference
+
+### lambda-cli Commands
+
+#### generate-kconfig
+Generate dynamic Kconfig files from API data.
+
+```bash
+lambda-cli generate-kconfig [--output-dir DIR]
+```
+
+**Output**: Creates `.generated` files with current API data
+
+#### instance-types list
+List available instance types.
+
+```bash
+lambda-cli --output json instance-types list [--available-only] [--region REGION]
+```
+
+**Output JSON Structure**:
+```json
+[
+ {
+ "name": "gpu_1x_a10",
+ "price_per_hour": "$0.75",
+ "specs": "1x NVIDIA A10 (24GB)",
+ "available_regions": 3
+ }
+]
+```
+
+#### smart-select
+Intelligently select instance and region.
+
+```bash
+lambda-cli --output json smart-select --mode cheapest
+```
+
+**Output JSON Structure**:
+```json
+{
+ "instance_type": "gpu_1x_a10",
+ "region": "us-west-1",
+ "price_per_hour": "$0.75",
+ "selection_mode": "cheapest_global"
+}
+```
+
+### Key Design Principles
+
+1. **Fallback Values**: Always provide sensible defaults when API is unavailable
+2. **Caching**: Cache API responses to avoid rate limits
+3. **Error Handling**: Graceful degradation when API fails
+4. **Separation of Concerns**:
+ - CLI tool for interface
+ - API library for communication
+ - Kconfig for configuration
+ - Makefile for orchestration
+
+### Testing Dynamic Generation
+
+```bash
+# Test API access
+scripts/lambda-cli --output json regions list
+
+# Test Kconfig generation
+make clean
+make menuconfig # Select Lambda Labs provider
+# Check generated files
+ls terraform/lambdalabs/kconfigs/*.generated
+
+# Test smart inference
+python3 scripts/lambdalabs_smart_inference.py instance
+python3 scripts/lambdalabs_smart_inference.py region
+```
+
+## Best Practices
+
+1. **API Key Management**
+ - Store in `~/.provider/credentials`
+ - Support environment variables
+ - Never commit keys to repository
+
+2. **Performance**
+ - Generate files only when provider is selected
+ - Cache API responses (15-minute TTL)
+ - Minimize API calls during configuration
+
+3. **User Experience**
+ - Provide clear status messages
+ - Show availability information
+ - Offer smart defaults
+ - Graceful fallbacks
+
+4. **Maintainability**
+ - Single CLI tool for all operations
+ - Consistent command structure
+ - Comprehensive error messages
+ - Well-documented API
+
+## Troubleshooting
+
+### Generated files not appearing
+```bash
+# Check if provider is enabled
+grep CONFIG_TERRAFORM_PROVIDER .config
+
+# Manually trigger generation
+make terraform/provider/kconfigs/Kconfig.compute.generated
+
+# Check for API errors
+scripts/provider-cli --output json instance-types list
+```
+
+### API authentication failures
+```bash
+# Check credentials
+scripts/provider_credentials.py check
+
+# Set credentials
+scripts/provider_credentials.py set YOUR_API_KEY
+```
+
+### Stale data in menus
+```bash
+# Force regeneration
+rm terraform/provider/kconfigs/*.generated
+make menuconfig
+```
+
+## Future Enhancements
+
+1. **Multi-Region Optimization**: Select instances across regions for best price/performance
+2. **Spot Instance Support**: Include spot pricing in smart selection
+3. **Resource Prediction**: Estimate resource needs based on workload
+4. **Cost Tracking**: Integration with cloud billing APIs
+5. **Availability Monitoring**: Real-time capacity updates
+
+## Contributing
+
+When adding a new cloud provider:
+1. Follow the Lambda Labs pattern
+2. Implement all required commands in CLI tool
+3. Provide comprehensive fallbacks
+4. Document API endpoints and data structures
+5. Add integration tests
+6. Update this documentation

From: Luis Chamberlain @ 2025-08-31 4:00 UTC (permalink / raw)
To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain, Your Name
Add comprehensive Kconfig system for Lambda Labs cloud provider:
- Main Kconfig: Provider overview and menu organization
- Kconfig.location: Region selection with smart inference modes
- Kconfig.compute: Instance type configuration with capacity info
- Kconfig.identity: SSH key management
- Kconfig.smart: Smart selection algorithms configuration
- Kconfig.storage: Placeholder for future storage features
Key features:
- Three selection modes: smart cheapest, smart inference, manual
- Dynamic region/instance generation based on API availability
- Complete region mappings including us-east-3 and other regions
- Provider limitations clearly documented
- Integration with dynamic configuration system
The Kconfig structure provides user-friendly configuration while
handling Lambda Labs provider constraints transparently.

+# Lambda Labs Terraform Provider for kdevops
+
+This directory contains the Terraform configuration for deploying kdevops infrastructure on Lambda Labs cloud GPU platform.
+
+> **Architecture Note**: Lambda Labs serves as the reference implementation for kdevops' dynamic cloud configuration system. For details on how the dynamic Kconfig generation works, see [Dynamic Cloud Kconfig Documentation](../../docs/dynamic-cloud-kconfig.md).
+
+## Table of Contents
+- [Prerequisites](#prerequisites)
+- [Quick Start](#quick-start)
+- [Dynamic Configuration](#dynamic-configuration)
+- [SSH Key Security](#ssh-key-security)
+- [Configuration Options](#configuration-options)
+- [Provider Limitations](#provider-limitations)
+- [Troubleshooting](#troubleshooting)
+- [API Reference](#api-reference)
+
+## Prerequisites
+
+1. **Lambda Labs Account**: Sign up at https://cloud.lambdalabs.com
+2. **API Key**: Generate at https://cloud.lambdalabs.com/api-keys
+3. **Terraform**: Version 1.0 or higher
+
+### API Key Setup
+
+Configure your Lambda Labs API key using the credentials file method:
+
+**Credentials File Configuration (Required)**
+```bash
+# Using the helper script:
+python3 scripts/lambdalabs_credentials.py set "your-api-key-here"
+
+# Or manually:
+mkdir -p ~/.lambdalabs
+cat > ~/.lambdalabs/credentials << EOF
+[default]
+lambdalabs_api_key = your-api-key-here
+EOF
+chmod 600 ~/.lambdalabs/credentials
+```
+
+The system uses file-based authentication for consistency with other cloud providers.
+Environment variables are NOT supported to avoid configuration complexity.
+
+## Quick Start
+
+```bash
+# Step 1: Configure API credentials
+python3 scripts/lambdalabs_credentials.py set "your-api-key"
+
+# Step 2: Generate cloud configuration (queries available instances)
+make cloud-config
+
+# Step 3: Configure for Lambda Labs with smart defaults
+make defconfig-lambdalabs
+
+# Step 4: Deploy infrastructure (SSH keys handled automatically)
+make bringup
+
+# Step 5: When done, clean up everything
+make destroy
+```
+
+## Dynamic Configuration
+
+Lambda Labs support includes dynamic configuration generation that queries the Lambda Labs API to provide:
+
+- **Real-time availability**: Only shows instance types with current capacity
+- **Smart defaults**: Automatically selects cheapest available instances
+- **Regional awareness**: Shows which regions have capacity for each instance type
+- **Current pricing**: Displays up-to-date pricing information
+
+### How It Works
+
+1. **API Query**: When you run `make cloud-config` or `make menuconfig`, the system uses `lambda-cli` to query Lambda Labs API
+2. **Kconfig Generation**: Available instances and regions are written to `.generated` files
+3. **Menu Integration**: Generated files are included in the Kconfig menu system
+4. **Smart Selection**: The system can automatically choose optimal configurations
+
+### lambda-cli Tool
+
+The `lambda-cli` tool is the central interface for Lambda Labs operations:
+
+```bash
+# List available instances
+scripts/lambda-cli instance-types list --available-only
+
+# Get pricing information
+scripts/lambda-cli pricing list
+
+# Smart selection (finds cheapest available)
+scripts/lambda-cli smart-select --mode cheapest
+
+# Generate Kconfig files
+scripts/lambda-cli generate-kconfig
+```
+
+### Manual API Queries
+
+You can manually query Lambda Labs availability:
+
+```bash
+# Check what's available right now
+scripts/lambda-cli --output json instance-types list --available-only
+
+# Check specific region
+scripts/lambda-cli --output json instance-types list --region us-west-1
+
+# Get current pricing
+scripts/lambda-cli --output json pricing list
+```
+
+For more details on the dynamic configuration system, see [Dynamic Cloud Kconfig Documentation](../../docs/dynamic-cloud-kconfig.md).
+
+## SSH Key Security
+
+### Automatic Unique Keys (Default - Recommended)
+
+Each kdevops project directory automatically gets its own unique SSH key:
+
+- **Key Format**: `kdevops-<project>-<hash>` (e.g., `kdevops-lambda-kdevops-611374da`)
+- **Automatic Creation**: Keys are created and uploaded on first `make bringup`
+- **Automatic Cleanup**: Keys are removed when you run `make destroy`
+- **No Manual Setup**: Everything is handled automatically
+
+### Legacy Shared Key Mode
+
+For backwards compatibility, you can use a shared key across projects:
+
+```bash
+# Use the shared key configuration
+make defconfig-lambdalabs-shared-key
+
+# Manually add your key to Lambda Labs console
+# https://cloud.lambdalabs.com/ssh-keys
+```
+
+### SSH Key Management Commands
+
+```bash
+# List all SSH keys in your account
+make lambdalabs-ssh-list
+
+# Manually setup project SSH key
+make lambdalabs-ssh-setup
+
+# Remove project SSH key
+make lambdalabs-ssh-clean
+
+# Direct CLI usage
+python3 scripts/lambdalabs_ssh_keys.py list
+python3 scripts/lambdalabs_ssh_keys.py add <name> <keyfile>
+python3 scripts/lambdalabs_ssh_keys.py delete <name_or_id>
+```
+
+## Configuration Options
+
+### Smart Instance Selection
+
+The default configuration automatically:
+1. Detects your geographic location from your public IP
+2. Queries Lambda Labs API for available instances
+3. Finds the cheapest available GPU instance
+4. Deploys to the closest region with that instance
+
+### Available Defconfigs
+
+| Config | Description | Use Case |
+|--------|-------------|----------|
+| `defconfig-lambdalabs` | Smart instance + unique SSH keys | Production (recommended) |
+| `defconfig-lambdalabs-shared-key` | Smart instance + shared SSH key | Legacy/testing |
+
+### Manual Configuration
+
+```bash
+# Configure specific options
+make menuconfig
+
+# Navigate to:
+# → Bring up methods → Terraform → Lambda Labs
+```
+
+Configuration options:
+- **Instance Type**: Choose specific GPU (or use smart selection)
+- **Region**: Choose specific region (or use smart selection)
+- **SSH Key Strategy**: Unique per-project or shared
+
+## Provider Limitations
+
+The Lambda Labs Terraform provider (elct9620/lambdalabs v0.3.0) has significant limitations:
+
+| Feature | Supported | Notes |
+|---------|-----------|-------|
+| Instance Creation | ✅ Yes | Basic instance provisioning |
+| GPU Selection | ✅ Yes | All Lambda Labs GPU types |
+| Region Selection | ✅ Yes | With availability checking |
+| SSH Key Reference | ✅ Yes | By name only |
+| OS Image Selection | ❌ No | Always Ubuntu 22.04 |
+| Custom User Creation | ❌ No | Always uses 'ubuntu' user |
+| Storage Volumes | ❌ No | Cannot attach additional storage |
+| User Data/Cloud-Init | ❌ No | No initialization scripts |
+| Network Configuration | ❌ No | Basic networking only |
+| SSH Key Creation | ❌ No | Must exist in console first |
+
+## Troubleshooting
+
+### SSH Authentication Failures
+
+**Problem**: `Permission denied (publickey)` when connecting
+
+**Solutions**:
+1. Verify SSH key exists in Lambda Labs:
+ ```bash
+ make lambdalabs-ssh-list
+ ```
+
+2. Check key name matches configuration:
+ ```bash
+ grep TERRAFORM_LAMBDALABS_SSH_KEY_NAME .config
+ ```
+
+3. Ensure using correct private key:
+ ```bash
+ ssh -i ~/.ssh/kdevops_terraform ubuntu@<instance-ip>
+ ```
+
+### No Capacity Available
+
+**Problem**: `No capacity available for instance type`
+
+**Solutions**:
+1. Smart inference automatically finds available regions
+2. Regenerate configs to check current availability:
+ ```bash
+ make cloud-config
+ cat terraform/lambdalabs/kconfigs/Kconfig.compute.generated | grep "✓"
+ ```
+3. Try different instance type or wait for capacity
+
+### API Key Issues
+
+**Problem**: `Invalid API key` or 403 errors
+
+**Solutions**:
+1. Verify credentials:
+ ```bash
+ cat ~/.lambdalabs/credentials
+ ```
+
+2. Test API access:
+ ```bash
+ python3 scripts/lambdalabs_list_instances.py
+ ```
+
+3. Generate new API key at https://cloud.lambdalabs.com/api-keys
+
+### Instance Creation Fails
+
+**Problem**: `Bad Request` when creating instances
+
+**Solutions**:
+1. Ensure SSH key exists with exact name
+2. Verify instance type is available in region
+3. Check terraform output:
+ ```bash
+ cd terraform/lambdalabs
+ terraform plan
+ ```
+
+## API Reference
+
+### Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `lambdalabs_api.py` | Main API integration, generates Kconfig |
+| `lambdalabs_smart_inference.py` | Smart instance/region selection |
+| `lambdalabs_ssh_keys.py` | SSH key management |
+| `lambdalabs_list_instances.py` | List running instances |
+| `lambdalabs_credentials.py` | Manage API credentials |
+| `lambdalabs_ssh_key_name.py` | Generate unique key names |
+| `generate_cloud_configs.py` | Update all cloud configurations |
+
+### Make Targets
+
+| Target | Description |
+|--------|-------------|
+| `cloud-config` | Generate/update cloud configurations |
+| `defconfig-lambdalabs` | Configure with smart defaults |
+| `bringup` | Deploy infrastructure |
+| `destroy` | Destroy infrastructure and cleanup |
+| `lambdalabs-ssh-list` | List SSH keys |
+| `lambdalabs-ssh-setup` | Setup SSH key |
+| `lambdalabs-ssh-clean` | Remove SSH key |
+
+### Authentication Architecture
+
+The Lambda Labs provider uses file-based authentication exclusively:
+
+1. **Credentials File**: `~/.lambdalabs/credentials` contains the API key
+2. **Extraction Script**: `extract_api_key.py` reads and validates the key
+3. **Terraform Integration**: External data source provides the key to the provider
+4. **No Environment Variables**: Consistent with AWS/GCE authentication patterns

From: Luis Chamberlain @ 2025-08-31 4:00 UTC (permalink / raw)
To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain, Your Name
Integrate Lambda Labs cloud provider into kdevops build system:
- Update Makefile infrastructure for dynamic configuration
- Add Lambda Labs to terraform provider selection menus
- Extend SSH configuration for Lambda Labs instances
- Add Ansible roles for tfvars generation and terraform execution
- Include Lambda Labs in shared terraform configuration
Changes:
- scripts/dynamic-kconfig.Makefile: Add cloud config targets
- scripts/terraform.Makefile: Lambda Labs terraform integration
- terraform/Kconfig.providers: Add Lambda Labs provider option
- terraform/Kconfig.ssh: Lambda Labs SSH configuration
- playbooks/roles/*: Ansible automation for deployment
This enables full kdevops workflow support for Lambda Labs including
configuration, provisioning, and instance management.

Enable Lambda Labs cloud provider in kdevops configuration system:
- kconfigs/Kconfig.bringup: Add Lambda Labs to bringup provider menu
- defconfigs/*: Add comprehensive example configurations
- lambdalabs-smart: Smart cheapest instance selection
- lambdalabs-gpu-*: GPU-specific configurations
- lambdalabs-shared-key: Shared SSH key setup
- PROMPTS.md: Document AI prompts used for development
Lambda Labs defconfig examples:
- Single GPU: A10, A100, H100 optimized configurations
- Multi-GPU: 8x A100, 8x H100 for ML workloads
- Smart selection: Automatic cheapest instance selection
- Shared infrastructure: Common SSH key management
This completes Lambda Labs integration, making it available
through standard kdevops configuration workflows.

is why we switched to an active ref prefix for the baseline and dev group

+## Cloud provider integrations
+
+### Adding Lambda Labs cloud provider support with dynamic Kconfig
+
+**Prompt:**
+The Lambda Labs company helps you use GPUs online, kind of like AWS, or OCI. Add
+support for the terraform support for Lambda Labs. The best provider docs are at
+https://registry.terraform.io/providers/elct9620/lambdalabs/latest/docs . Then
+To create the kconfig values you will implement support to use the lambda cloud
+API to let us query for what type of instances they have available and so forth.
+Therefore the Kconfig stuff for Lambda labs will all be dynamic. So we'll want
+to expand this as part of what make dynconfig does. However note that dynconfig
+does *all* dynamically generated kconfig. We want to add support for make
+cloud-config as a new target which is dynamic which is a subset of make
+dynconfig ; OK! good luck
+
+**AI:** Claude Code (Opus 4.1)
+**Commit:** [To be determined]
+**Result:** Complete Lambda Labs integration with dynamic Kconfig generation.
+**Grading:** 75%
+
+**Notes:**
+
+The implementation successfully added:
+
+1. **Terraform Provider Integration**: Created complete Terraform configuration
+ for Lambda Labs including instance management, persistent storage, and SSH
+ configuration management following existing cloud provider patterns.
+
+2. **Dynamic Kconfig Generation**: Implemented Python script to query Lambda Labs
+ API for available instance types, regions, and OS images. Generated dynamic
+ Kconfig files with fallback defaults when API is unavailable.
+
+3. **Build System Integration**: Added `make cloud-config` as a new target for
+ cloud-specific dynamic configuration, properly integrated with `make dynconfig`.
+ Created modular Makefile structure for cloud provider dynamic configuration.
+
+4. **Kconfig Structure**: Properly integrated Lambda Labs into the provider
+ selection system with modular Kconfig files for location, compute, storage,
+ and identity management.
+
+Biggest issues:
+
+1. **SSH Management**: For this it failed to realize the provider
+ didn't suport asking for a custom username, so we had to find out the
+ hard way.
+
+2. **Environment variables**: For some reason it wanted to define the
+ credential API as an environment variable. This proved painful as some
+ environment variables do not carry over for some ansible tasks. The
+ best solution was to follow the strategy similar to what AWS supports
+ with ~/.lambdalabs/credentials. This a more secure alternative.
+
+Minor issues:

With a few minor sytling fixes and CI test fixes (had to ensure to run
touch on generated files), and fixing the SOB, I pushed this series.
