Add gitignore patterns for Lambda Labs files that will be dynamically
generated or created during runtime. These include:
- Dynamic Kconfig files generated from API queries
- Terraform API key storage
- Cloud initialization marker
- Python cache directories
This prepares the repository for Lambda Labs cloud provider support by
ensuring generated files won't be accidentally committed.

Add a Python library for interacting with the Lambda Labs cloud API.
This provides core functionality to query instance types, regions,
availability, and manage cloud resources programmatically.
The API library handles:
- Instance type enumeration and capacity checking
- Region availability queries
- SSH key management operations
- Error handling and retries for API calls
- Parsing and normalizing API responses
This forms the foundation for dynamic Kconfig generation and terraform
integration, but doesn't enable any features yet.

Thanks for splitting this up. Much much easier for humble humans to
understand now. There are some really interesting ideas in the series;
kudos to you and Claude.
The other cloud providers have their own house-brewed command line
utilities that are typically packaged by distributions (eg, oci, aws,
and so on), as well as their own Ansible collections.
I assume that Lambda does not have those (yet). Can the patch
description mention that? Basically that's the whole purpose for this
patch and the two following, IIUC.
I would actually encourage this script to be restructured and renamed so
that it works like the tooling available from other cloud providers.
Separate the API calls and retrieval of information (which is rather
general purpose) from the translation of that information to Kconfig
menus (which is specific to kdevops).
General comment: it might be cleaner and more extensible if the Python
used Jinja2 templating to generate the Kconfig files.
One more remark, far below:

IMHO this comment is important for kdevops users to be aware of too.
Maybe it should go in a top-level Kconfig help section instead of being
an internal comment.
The storage configuration bit is most interesting to me... since that
means the volumes submodule is not coming over to the Lamba terraform
in this iteration. That's OK, that's not what you're testing with this
one.

Right. It sad to not see such a thing, which meant it was actually
harder to do this inference work, and yet it shows its possible. Which
also means, technically in theory, it might even be possible to do the
same with other cloud providers without a CLI tool.

So you mean we write Lambda's CLI tool? Sure we can try that, but who do
we follow? And do we need to do that now? Or can I do that later?

You mean, to re-use all the knowledge we used for Kconfig dynamic
kconfig to a create a specific tool, which can then be itself leveraged
for both the dynamic kconfig and also a user tool?

I *love* Jinja2, even though it originally was an April Fool's joke,
however, my experience with it is its extremely limitting since the
amount of dynamic programability is limited, and also extremely
difficult to read. See playbooks/roles/gen_nodes/templates/gen_drives.j2
as an example.
So I am not sure, I think for cloud with an explosion of varaibility,
it would be super complicatd to manage with jinja2.

Yup, I reached out to them, and they gave me this:
https://cloud.lambda.ai/api/v1/docs#post-/api/v1/filesystems
So it actualy seems that's our outlet, however unfortunately we can't
create our own filesystem, this is just NFS behind the scenes.
So -- at least we can *create* new "volumes".

I think so: Write a command line tool that makes API queries and spits
out JSON. Write a second tool that takes the JSON and turns it into
Kconfig menus. Re-use the first tool for other tasks. That is how I
was thinking of building dynamic menus for the other providers; their
existing command line tools are tool #1 above.
But, we can do it later. I won't hold you up with crazy ideas.

Yeah I think this is really *it*!

Its not crazy at all, proper architecture trumps all. But if we didn't
start evaluating this patch series with this inference cloud thing for
dynamic kconfig thing we wouldn't have ended up here. And so I think we
have a solid path.
I'd like to extend your suggestion further: I am not sure if we need a
different CLI tool per cloud provider. Wouldn't it be nice if we had
unified way to query such things and output json for each cloud
provider?

Basically I'm re-using the tools each provider gives us because, well,
I'm a lazy sod. It gives some immediate traction.
But I can see that doing it that way means we have a distinct JSON to
Kconfig translation for each provider.
If handling the API queries is as easy as the Python script here looks,
then the only hard part to building a single tool will be turning the
provider-specific JSON into something common (and YAML output might be
easier for Ansible and Python to deal with than JSON, IMO).

I see the challenges ahead, yeah screw it. Let's for now diverge and
later we can evaluate. I don't think we *need* a common tool other than
a utopian dream of sharing dynamic kconfig generation scripts. That can
wait until we have each cloud provider set up.

Add secure credentials management for Lambda Labs API keys following
the AWS-style approach with ~/.lambdalabs/credentials file. This avoids
environment variable complexity and provides a secure, persistent way
to store API credentials.
Features:
- File-based credential storage (~/.lambdalabs/credentials)
- Profile support (default profile for now)
- Secure file permissions (600)
- Commands to set, get, check, and clear credentials
- Validation and testing utilities
This provides the authentication foundation needed by the API library
but doesn't enable any user-facing features yet.

From: Luis Chamberlain @ 2025-08-27 21:28 UTC (permalink / raw)
To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Add utilities for managing SSH keys with Lambda Labs cloud instances.
This includes automatic key upload, verification, and SSH config
management with per-directory isolation to support multiple kdevops
instances.
Key features:
- Upload and manage SSH keys via API
- Per-directory SSH key isolation using directory checksums
- SSH config file management and updates
- Key verification and listing utilities
- Automatic key creation workflow support
The per-directory isolation ensures each kdevops workspace uses unique
SSH keys, preventing conflicts when running multiple instances.

From: Luis Chamberlain @ 2025-08-27 21:28 UTC (permalink / raw)
To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Introduce a new dynamic configuration system that queries cloud provider
APIs to generate real-time Kconfig options. This allows configuration
menus to show current availability and capacity directly from the cloud.
The system adds:
- Python script to query APIs and generate Kconfig files
- New 'make cloud-config' target for cloud-specific updates
- Integration with existing 'make dynconfig' infrastructure
- CLOUD_INITIALIZED marker to detect cloud setup state
- Automatic fallback to static defaults when API unavailable
This sets up the framework for API-driven configuration but doesn't
enable any specific providers yet. The architecture supports future
extension to AWS, Azure, GCE, and other cloud providers.

To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Add the Kconfig menu structure for Lambda Labs cloud provider. This
includes configuration options for:
- Instance type selection (with dynamic and manual modes)
- Region selection
- SSH key management options
- Smart instance inference based on cost and availability
- Persistent storage configuration
- OS image selection
The configuration is structured with modular Kconfig files:
- Main Lambda Labs configuration entry point
- Compute resources (instance types)
- Location settings (regions)
- Identity management (SSH keys)
- Storage options
- Smart selection logic
This provides the configuration structure but doesn't enable Lambda Labs
in the provider menu yet, maintaining build stability.

Add the terraform provider implementation for Lambda Labs GPU cloud
instances. This includes the core terraform configuration to provision
and manage cloud resources.
The implementation provides:
- Main terraform resource definitions for instances
- Provider configuration with API key extraction
- Variable definitions for all configurable options
- Output definitions for instance information
- Ansible provisioning template
- API key helper script for credential extraction
- Documentation for Lambda Labs setup and usage
The terraform code handles:
- Instance creation with selected GPU types
- SSH key configuration
- Persistent storage attachment
- Network configuration
- Instance metadata and tagging

+# Lambda Labs Terraform Provider for kdevops
+
+This directory contains the Terraform configuration for deploying kdevops infrastructure on Lambda Labs cloud GPU platform.
+
+## Table of Contents
+- [Prerequisites](#prerequisites)
+- [Quick Start](#quick-start)
+- [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
+```
+
+## 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

Wire Lambda Labs into the kdevops build and provisioning system. This
adds the necessary Ansible playbook tasks, terraform variable templates,
and Makefile targets to support Lambda Labs operations.
Integration includes:
- Terraform tfvars template for Lambda Labs configuration
- Ansible defaults for Lambda Labs variables
- API key validation in terraform workflow
- Capacity checking before provisioning
- SSH key management in Makefile targets
- Per-directory SSH key isolation in Kconfig
- Updated shared terraform configuration
The integration ensures:
- API keys are validated before provisioning attempts
- Capacity is checked to avoid failed provisions
- SSH keys are managed automatically when configured

To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Add utility scripts for testing, debugging, and managing Lambda Labs
cloud resources. These tools help developers validate configurations,
debug issues, and manage instances.
Testing utilities:
- Capacity checking before provisioning
- SSH connectivity testing
- API endpoint validation
- Credential verification
Management utilities:
- Instance listing and status checking
- Smart instance selection based on cost/availability
- Region inference for optimal placement
- Cloud provider comparison tool
Debugging utilities:
- API response exploration
- Debug script for troubleshooting API issues
- Instance update helper
Also documents the Lambda Labs implementation in PROMPTS.md for future
reference and improvement.

+## 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:
+- Some whitespace formatting was automatically fixed by the linter

To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Enable Lambda Labs as a selectable cloud provider and add example
configurations to help users get started quickly. Lambda Labs is now
fully integrated and available for use.
This patch:
- Adds Lambda Labs to the cloud provider selection menu
- Sources Lambda Labs Kconfig when selected
- Provides example defconfigs for common GPU configurations
- Includes smart selection and cost-optimized examples
- Adds shared SSH key configuration example
Example configurations provided:
- lambdalabs: Basic Lambda Labs setup
- lambdalabs-gpu-1x-a10: Single A10 GPU instance
- lambdalabs-gpu-1x-a100: Single A100 GPU instance
- lambdalabs-gpu-1x-h100: Single H100 GPU instance
- lambdalabs-gpu-8x-a100: 8x A100 GPU cluster
- lambdalabs-gpu-8x-h100: 8x H100 GPU cluster
- lambdalabs-smart: Smart instance selection
- lambdalabs-shared-key: Shared SSH key setup
Lambda Labs is now ready for GPU-accelerated workloads with dynamic
configuration based on real-time API data.
