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.

This is why we switched to an active ref prefix for the baseline and dev group ref tags. + +## 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.
