Changes on this v2:
- adds the docs suggested by Chuck
- splits GPU amis in a separate patch
- drops the static files, as they are just noise
and I can instead re-generate them on the fly when
we decide this is ready to merge.
I've also changed the default GPU AMI to use
"Deep Learning OSS Nvidia Driver AMI GPU PyTorch*Ubuntu 22.04*" as that
actually has pytorch.

Add support for dynamically generating AWS instance types and regions
configuration using the AWS CLI, similar to the Lambda Labs implementation.
This allows users to:
- Query real-time AWS instance availability
- Generate Kconfig files with current instance families and regions
- Choose between dynamic and static configuration modes
- See pricing estimates and resource summaries
Key components:
- scripts/aws-cli: AWS CLI wrapper tool for kdevops
- scripts/aws_api.py: Low-level AWS API functions (includes GPU AMI query functions)
- Updated generate_cloud_configs.py to support AWS
- Makefile integration for AWS Kconfig generation
- Option to use dynamic or static AWS configuration
- Documentation for cloud configuration management
Usage: Run 'make cloud-config' to generate dynamic configuration.
This parallelizes cloud provider operations to significantly improve
generation time. The cloud-update target allows administrators to
convert generated configs to static files for regular users to avoid
the ~6 minute generation time.

+# Cloud Configuration Management in kdevops
+
+kdevops supports dynamic cloud provider configuration, allowing administrators to generate up-to-date instance types, locations, and AMI options directly from cloud provider APIs. Since generating these configurations can take several minutes (approximately 6 minutes for AWS), kdevops implements a two-tier system to optimize the user experience.
+
+## Overview
+
+The cloud configuration system follows a pattern similar to Linux kernel refs management (`make refs-default`), where administrators generate fresh configurations that are then committed to the repository as static files for regular users. This approach provides:
+
+- **Fast configuration loading** for regular users (using pre-generated static files)
+- **Fresh, up-to-date options** when administrators regenerate configurations
+- **No dependency on cloud CLI tools** for regular users
+- **Reduced API calls** to cloud providers
+
+## Configuration Generation Flow
+
+```
+Cloud Provider API → Generated Files → Static Files → Git Repository
+ ↑ ↑ ↑
+ make cloud-config (automatic) make cloud-update
+```
+
+## Available Targets
+
+### `make cloud-config`
+
+Generates dynamic cloud configurations by querying cloud provider APIs.
+
+**Purpose**: Fetches current instance types, regions, availability zones, and AMI options from cloud providers.
+
+**Usage**:
+```bash
+make cloud-config
+```
+
+**What it does**:
+- Queries AWS EC2 API for all available instance types and their specifications
+- Fetches current regions and availability zones
+- Discovers available AMIs including GPU-optimized images
+- Generates Kconfig files with all discovered options
+- Creates `.generated` files in provider-specific directories
+- Sets a marker file (`.aws_cloud_config_generated`) to enable dynamic config
+
+**Time required**: Approximately 6 minutes for AWS (similar for other providers)
+
+**Generated files**:
+- `terraform/aws/kconfigs/Kconfig.compute.generated`
+- `terraform/aws/kconfigs/Kconfig.location.generated`
+- `terraform/aws/kconfigs/Kconfig.gpu-amis.generated`
+- `terraform/aws/kconfigs/instance-types/Kconfig.*.generated`
+- Similar files for other cloud providers
+
+### `make cloud-update`
+
+Converts dynamically generated configurations to static files for committing to git.
+
+**Purpose**: Creates static copies of generated configurations that load instantly without requiring cloud API access.
+
+**Usage**:
+```bash
+make cloud-update
+```
+
+**What it does**:
+- Copies all `.generated` files to `.static` equivalents
+- Updates internal references from `.generated` to `.static`
+- Prepares files for git commit
+- Allows regular users to benefit from pre-generated configurations
+
+**Static files created**:
+- All `.generated` files get `.static` counterparts
+- References within files are updated to use `.static` versions
+
+### `make clean-cloud-config`
+
+Removes all generated cloud configuration files.
+
+**Usage**:
+```bash
+make clean-cloud-config
+```
+
+**What it does**:
+- Removes all `.generated` files
+- Removes cloud initialization marker files
+- Forces regeneration on next `make cloud-config`
+
+## Usage Workflow
+
+### For Cloud Administrators/Maintainers
+
+Cloud administrators are responsible for keeping the static configurations up-to-date:
+
+1. **Generate fresh configurations**:
+ ```bash
+ make cloud-config # Wait ~6 minutes for API queries
+ ```
+
+2. **Convert to static files**:
+ ```bash
+ make cloud-update # Instant - just copies files
+ ```
+
+3. **Commit the static files**:
+ ```bash
+ git add terraform/*/kconfigs/*.static
+ git add terraform/*/kconfigs/instance-types/*.static
+ git commit -m "cloud: update static configurations for AWS/Azure/GCE
+
+ Update instance types, regions, and AMI options to current offerings.
+
+ Generated with AWS CLI version X.Y.Z on YYYY-MM-DD."
+ git push
+ ```
+
+### For Regular Users
+
+Regular users benefit from pre-generated static configurations:
+
+1. **Clone or pull the repository**:
+ ```bash
+ git clone https://github.com/linux-kdevops/kdevops
+ cd kdevops
+ ```
+
+2. **Use cloud configurations immediately**:
+ ```bash
+ make menuconfig # Cloud options load instantly from static files
+ make defconfig-aws-large
+ make
+ ```
+
+No cloud CLI tools or API access required - everything loads from committed static files.
+
+## How It Works
+
+### Dynamic Configuration Detection
+
+kdevops automatically detects whether to use dynamic or static configurations:
+
+```kconfig
+config TERRAFORM_AWS_USE_DYNAMIC_CONFIG
+ bool "Use dynamically generated instance types"
+ default $(shell, test -f .aws_cloud_config_generated && echo y || echo n)
+```
+
+- If `.aws_cloud_config_generated` exists, dynamic configs are used
+- Otherwise, static configs are used (default for most users)
+
+### File Precedence
+
+The Kconfig system sources files in this order:
+
+1. **Static files** (`.static`) - Pre-generated by administrators
+2. **Generated files** (`.generated`) - Created by `make cloud-config`
+
+Static files take precedence and are preferred for faster loading.
+
+### Instance Type Organization
+
+Instance types are organized by family for better navigation:
+
+```
+terraform/aws/kconfigs/instance-types/
+├── Kconfig.m5.static # M5 family instances
+├── Kconfig.m7a.static # M7a family instances
+├── Kconfig.g6e.static # G6E GPU instances
+└── ... # Other families
+```
+
+## Supported Cloud Providers
+
+### AWS
+- **Instance types**: All EC2 instance families and sizes
+- **Regions**: All AWS regions and availability zones
+- **AMIs**: Standard distributions and GPU-optimized Deep Learning AMIs
+- **Time to generate**: ~6 minutes
+
+### Azure
+- **Instance types**: All Azure VM sizes
+- **Regions**: All Azure regions
+- **Images**: Standard and specialized images
+- **Time to generate**: ~5-7 minutes
+
+### Google Cloud (GCE)
+- **Instance types**: All GCE machine types
+- **Regions**: All GCE regions and zones
+- **Images**: Public and custom images
+- **Time to generate**: ~5-7 minutes
+
+### Lambda Labs
+- **Instance types**: GPU-optimized instances
+- **Regions**: Available data centers
+- **Images**: ML-optimized images
+- **Time to generate**: ~1-2 minutes
+
+## Benefits
+
+### For Regular Users
+- **Instant configuration** - No waiting for API queries
+- **No cloud CLI required** - Works without AWS CLI, gcloud, or Azure CLI
+- **Consistent experience** - Same options for all users
+- **Offline capable** - Works without internet access
+
+### For Administrators
+- **Centralized updates** - Update once for all users
+- **Version control** - Track configuration changes over time
+- **Reduced API calls** - Query once, use many times
+- **Flexibility** - Can still generate fresh configs when needed
+
+## Best Practices
+
+1. **Update regularly**: Cloud administrators should regenerate configurations monthly or when significant changes occur
+
+2. **Document updates**: Include cloud CLI version and date in commit messages
+
+3. **Test before committing**: Verify generated configurations work correctly:
+ ```bash
+ make cloud-config
+ make cloud-update
+ make menuconfig # Test that options appear correctly
+ ```
+
+4. **Use defconfigs**: Create defconfigs for common cloud configurations:
+ ```bash
+ make savedefconfig
+ cp defconfig defconfigs/aws-gpu-large
+ ```
+
+5. **Handle errors gracefully**: If cloud-config fails, static files still work
+
+## Troubleshooting
+
+### Configuration not appearing in menuconfig
+
+Check if dynamic config is enabled:
+```bash
+ls -la .aws_cloud_config_generated
+grep USE_DYNAMIC_CONFIG .config
+```
+
+### Generated files have wrong references
+
+Run `make cloud-update` to fix references from `.generated` to `.static`.
+
+### Old instance types appearing
+
+Regenerate configurations:
+```bash
+make clean-cloud-config
+make cloud-config
+make cloud-update
+```
+
+## Implementation Details
+
+The cloud configuration system is implemented in:
+
+- `scripts/dynamic-cloud-kconfig.Makefile` - Make targets and build rules
+- `scripts/aws_api.py` - AWS configuration generator
+- `scripts/generate_cloud_configs.py` - Main configuration generator
+- `terraform/*/kconfigs/` - Provider-specific Kconfig files

From: Luis Chamberlain @ 2025-09-07 4:23 UTC (permalink / raw)
To: Chuck Lever, Daniel Gomez, kdevops; +Cc: Luis Chamberlain
Add support for GPU-optimized AMIs when using GPU instance types.
This includes:
- AWS Deep Learning AMI with pre-installed NVIDIA drivers, CUDA, and
ML frameworks
- NVIDIA Deep Learning AMI option for NGC containers
- Custom GPU AMI support for specialized images
- Automatic detection of GPU instance types
- Conditional display of GPU AMI options only for GPU instances
- Update terraform.tfvars template to use GPU AMI when configured
- Add defconfig for AWS G6e.2xlarge GPU instance with Deep Learning AMI
The system automatically detects when you select a GPU instance family
(like G6E) and provides appropriate GPU-optimized AMI options including
the AWS Deep Learning AMI with all necessary drivers and frameworks
pre-installed.

Thanks, this is very helpful.
I want to pull this some time this week and try it out. Is it in a
public branch?
A few more comments below. Quite possibly you could merge this and
we can just start polishing once it is merged.

I expect that a CLI tool or cloud console access /is/ needed to generate
authentication tokens, so this claim ought to be more specific.

In terms of usability, why does the kdevops user need to config/enable
dynamic menu building? Can we just replace the menu files I wrote
with the generated menus, wholesale, with this patch? Seems like there
is sensible default behavior for users after a simple "git clone
kdevops" -- the same set of make targets will work the same way.
Or to put it another way, for me the merge criteria for this patch is
that it can generate a set of working AWS menus that are a superset of
what is already in the tree now. I'm not seeing a need to turn this
facility on or off. If there is a need for disabling it, can you add it
to the patch description or Kconfig help text?

Again, I'm missing the difference between .generated and .static. It
might be simpler overall if we just moved forward with all generated
Kconfig menus.

Not clear to me... is this script simply returning a constant blob
of JSON, or is there a real API query going on? The comments here
suggest there is more to be done here. (Just an observation).
Also, see below: I'm not sure why we need to keep a lot of default
information around in this script. Either the menu regeneration
worked and replaces the previous one (and can be backed out via
a normal revert) or regeneration doesn't work, in which case the
menus shouldn't change.
We always have the safety net of git to quickly get back to a working
configuration: something like "git reset --hard".

Great, glad it was. BTW just one request, any chance you can trim
context over your replies, like I did here? Otherwise it becomes
a bit hard to scroll down on longer patches for your reviews. Likewise,
you can just trim the end of a message if no extra context is provided
at the end. The other reason this is useful is it can be useful to
reduce context window for AIs to process. Although I'm not an AI,
I sometimes test AIs to try to evaluate how well they can process
replies to adjust patches. In the future I hope this to be a standard
test.

Yes sure, just pushed now, but I didn't include the static files, so
you can generate them yourself. The static files are just noise in a
temporary branch, as its automatically generated kconfig files, best
you run `make cloud-update` yourself to see for yourself.

Up to you! Let me know! Since its in a branch now, you can also take
a peak and if you generate the static files, you can generate / add
them and commit / push yourself. That way its not just me who believes
the magic, but its goes tested then by another developer who can grok
this.
You could also test feeding Claude Code this thread to see if it can
adjust the changes.

- **No dependency on cloud CLI tools** for regular users
- **Reduced API calls** to cloud providers
+## Prerequisites for Cloud Providers
+
+### AWS Prerequisites
+
+The AWS dynamic configuration system uses the official AWS CLI tool and requires proper authentication to access AWS APIs.
+
+#### Requirements
+
+1. **AWS CLI Installation**
+ ```bash
+ # Using pip
+ pip install awscli
+
+ # On Debian/Ubuntu
+ sudo apt-get install awscli
+
+ # On Fedora/RHEL
+ sudo dnf install aws-cli
+
+ # On macOS
+ brew install awscli
+ ```
+
+2. **AWS Credentials Configuration**
+
+ You need valid AWS credentials configured in one of these ways:
+
+ a. **AWS credentials file** (`~/.aws/credentials`):
+ ```ini
+ [default]
+ aws_access_key_id = YOUR_ACCESS_KEY
+ aws_secret_access_key = YOUR_SECRET_KEY
+ ```
+
+ b. **Environment variables**:
+ ```bash
+ export AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY
+ export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY
+ export AWS_DEFAULT_REGION=us-east-1 # Optional
+ ```
+
+ c. **IAM Instance Role** (when running on EC2):
+ - Automatically uses instance metadata service
+ - No explicit credentials needed
+
+3. **Required AWS Permissions**
+
+ The IAM user or role needs the following read-only permissions:
+ ```json
+ {
+ "Version": "2012-10-17",
+ "Statement": [
+ {
+ "Effect": "Allow",
+ "Action": [
+ "ec2:DescribeRegions",
+ "ec2:DescribeAvailabilityZones",
+ "ec2:DescribeInstanceTypes",
+ "ec2:DescribeImages",
+ "pricing:GetProducts"
+ ],
+ "Resource": "*"
+ },
+ {
+ "Effect": "Allow",
+ "Action": [
+ "sts:GetCallerIdentity"
+ ],
+ "Resource": "*"
+ }
+ ]
+ }
+ ```
+
+#### Verifying AWS Setup
+
+Test your AWS CLI configuration:
+```bash
+# Check AWS CLI is installed
+aws --version
+
+# Verify credentials are configured
+aws sts get-caller-identity
+
+# Test EC2 access
+aws ec2 describe-regions --output table
+```
+
+#### Fallback Behavior
+
+If AWS CLI is not available or credentials are not configured:
+- The system automatically falls back to pre-defined static defaults
+- Basic instance families (M5, T3, C5, etc.) are still available
+- Common regions (us-east-1, eu-west-1, etc.) are provided
+- Default GPU AMI options are included
+- Users can still use kdevops without AWS API access
+
+### Lambda Labs Prerequisites
+
+Lambda Labs configuration requires an API key:
+
+1. **Obtain API Key**: Sign up at [Lambda Labs](https://lambdalabs.com) and generate an API key

## How It Works
+### Implementation Architecture
+
+The cloud configuration system consists of several key components:
+
+1. **API Wrapper Scripts** (`scripts/aws-cli`, `scripts/lambda-cli`):
+ - Provide CLI interfaces to cloud provider APIs
+ - Handle authentication and error checking
+ - Format API responses for Kconfig generation
+
+2. **API Libraries** (`scripts/aws_api.py`, `scripts/lambdalabs_api.py`):
+ - Core functions for API interactions
+ - Generate Kconfig syntax from API data
+ - Provide fallback defaults when APIs unavailable
+
+3. **Generation Orchestrator** (`scripts/generate_cloud_configs.py`):
+ - Coordinates parallel generation across providers
+ - Provides summary information
+ - Handles errors gracefully
+
+4. **Makefile Integration** (`scripts/dynamic-cloud-kconfig.Makefile`):
+ - Defines make targets
+ - Manages file dependencies
+ - Handles cleanup and updates
+
+### AWS Implementation Details
+
+The AWS implementation wraps the official AWS CLI tool rather than implementing its own API client:
+
+```python
+# scripts/aws_api.py
+def run_aws_command(command: List[str], region: str = None) -> Optional[Any]:
+ cmd = ["aws"] + command + ["--output", "json"]
+ # ... executes via subprocess
+```
+
+Key features:
+- **Parallel Generation**: Uses ThreadPoolExecutor to generate instance family files concurrently
+- **GPU Detection**: Automatically identifies GPU instances and enables GPU AMI options
+- **Categorized Instance Types**: Groups instances by use case (general, compute, memory, etc.)
+- **Pricing Integration**: Queries pricing API when available
+- **Smart Defaults**: Falls back to well-tested defaults when API unavailable

+aws --version
+
+# Install if missing (see Prerequisites section)
+```
+
+#### "Credentials not configured" Error

+
+#### "Access Denied" Errors
+- Verify your IAM user/role has the required permissions (see Prerequisites)
+- Check if you're in the correct AWS account
+- Ensure your credentials haven't expired
+
+#### Slow Generation Times
+- Normal for AWS (6+ minutes due to API pagination)

+
+#### Missing Instance Types
+```bash
+# Force regeneration
+make clean-cloud-config
+make cloud-config
+make cloud-update
+```
+
+### General Issues
+
+#### Static Files Not Loading
+```bash
+# Verify static files exist
+ls terraform/aws/kconfigs/*.static
+
+# If missing, regenerate:
+make cloud-config
+make cloud-update
+```
+
+#### Changes Not Reflected in Menuconfig
+```bash
+# Clear Kconfig cache
+make mrproper
+make menuconfig
+```
+
+#### Debugging API Calls
+```bash
+# Enable debug output
+export DEBUG=1
+make cloud-config
+
+# Test API directly
+scripts/aws-cli --output json regions list
+scripts/aws-cli --output json instance-types list --family m5
+```
+
+## Best Practices
+
+1. **Regular Updates**: Administrators should regenerate configurations monthly or when new instance types are announced
+
+2. **Commit Messages**: Include generation date and tool versions when committing static files:
+ ```bash
+ git commit -m "cloud: update AWS static configurations
+
+ Generated with AWS CLI 2.15.0 on 2024-01-15
+ - Added new G6e instance family
+ - Updated GPU AMI options
+ - 127 instance families now available"
+ ```
+
+3. **Testing**: Always test generated configurations before committing:
+ ```bash
+ make cloud-config
+ make cloud-update
+ make menuconfig # Verify options appear correctly
+ ```
+
+4. **Partial Generation**: For faster testing, generate only specific providers:
+ ```bash
+ make cloud-config-aws # AWS only
+ make cloud-config-lambdalabs # Lambda Labs only
+ ```
+
+5. **CI/CD Integration**: Consider automating configuration updates in CI pipelines
+
+## Advanced Usage
+
+### Custom AWS Profiles
+```bash
+# Use non-default AWS profile
+export AWS_PROFILE=myprofile
+make cloud-config
+```
+
+### Specific Region Generation
+```bash
+# Generate for specific region (affects default selections)
+export AWS_DEFAULT_REGION=eu-west-1
+make cloud-config
+```
+
+### Parallel Generation
+The system automatically uses parallel processing:
+- AWS: Up to 10 concurrent instance family generations
+- Reduces total generation time significantly
+
+## File Reference
+
+### AWS Files
+- `terraform/aws/kconfigs/Kconfig.compute.{generated,static}` - Instance families
+- `terraform/aws/kconfigs/Kconfig.location.{generated,static}` - Regions and zones
+- `terraform/aws/kconfigs/Kconfig.gpu-amis.{generated,static}` - GPU AMI options
+- `terraform/aws/kconfigs/instance-types/Kconfig.*.{generated,static}` - Per-family sizes
+
+### Marker Files
+- `.aws_cloud_config_generated` - Enables dynamic AWS config
+- `.cloud.initialized` - General cloud config marker
+
+### Scripts
+- `scripts/aws-cli` - AWS CLI wrapper with user-friendly commands
+- `scripts/aws_api.py` - AWS API library and Kconfig generation
+- `scripts/generate_cloud_configs.py` - Main orchestrator for all providers
+- `scripts/dynamic-cloud-kconfig.Makefile` - Make targets and integration

The only rationale for disabling it is if users relied on old defconfigs
which may not fit with the new style meant to be dynamic. Some kconfig
symbols may have changed. I have not vetted them all. However, if we
don't really have users (I don't think we do) of AWS defconfigs, perhaps
this is a non-issue we can wholely replace the old stuff with the new
dynamic stuff.
I just decided to go with the conservative approach so we can discuss
this a bit more.
My spidy senses tell me we should be able to full on replace the old
static stuff with a new world order. But more broad users of cloud
suport should chime in. I think our larger user base may be OCI users.
So for OCI I suspect more care is needed. For AWS I think we're safe
to replace old static files for the dynamically generated ones.

They're the same, its just we want to .gitignore .generated content, the
.static files are the version of the same files *in tree* from a trusted
developer who ran the latest:
make cloud-config
make cloud-update
A developer may find that make cloud-config could use some more
refinements, and that lets them have their cake, by leveraging the
dynamic content not yet upstream.

Claude Code said:
------
1. Current Implementation: The function contains hardcoded pricing for common instance types:
- Lines 209-276 contain a static dictionary with hardcoded prices
- Comment on line 208 explicitly states: "For simplicity, we'll use hardcoded common instance prices"
- Comment also notes: "In production, you'd query the AWS Pricing API"
2. Regional Adjustment: The function does apply regional multipliers (lines 280-298), but these are also hardcoded:
region_multipliers = {
"us-east-1": 1.0,
"us-west-2": 1.0,
"us-west-1": 1.08, # 8% more expensive
"eu-west-1": 1.1, # 10% more expensive
# etc.
}
3. Why Not Real API?: The AWS Pricing API is complex and requires:
- Special endpoint (only available in us-east-1)
- Complex query structure with filters
- Different response format than other EC2 APIs
- Additional permissions (pricing:GetProducts)
4. Impact: This means:
- Prices shown are approximate/outdated
- Many instance types have no pricing data
- New instance types won't have prices
- The prices are used mainly for sorting/display hints, not billing
This is a reasonable simplification for the current use case since
kdevops primarily needs instance type specifications (vCPUs, memory,
etc.) rather than accurate pricing. The hardcoded prices provide a
general sense of relative costs between instance families.

So yeah a TODO item.

I'm happy for us to agree to remove the old stuff. It just requires
more eyeballs / review / consensus. Long long ago, we dreamed this
might be a possibility. Now its here, and on our fingertips. I was
happy to be cautious of this at first. Happier to go full swing mode
if we are feeling good about the strategy.

A probably scalable way to address this may be to get the users who
care to just test it out, and if we're happy, we move forward. I
can't realistically expect this to not work at this point. Its more
about architecture, and gaining confidence if this is the right
approach.
Ideally we may also want to evaluate automation of the smallest few
instances, but the issue is what credits to use. Perhaps something
we can bench for later. This is the sort of stuff I'd hope AWS would
be interested in sponsoring a few credits, specially as we venture into
GPU support / automation.

Sure.

I think you're spot on.
I'll let you decide on to merge this or not. Alternatively feel free to
ask Claude Code to read this reply and I confident it could adjust the code
based on your feedback. I'd recommend to just ask it to make atomic
commits for your review, and you could then squash.
If you like I could also try the same myself and post a v3. Let me know!
BTW I make these side statements over how to merge code just because of
my sensing of new paradigms in development over how to adjust to new
codebases which properly embrace genai where confidence is already high.
I think linting merges are one good example, and automated patch review
and changes yet another to consider. This, to help scale rapid evolution.
That is, latencies on typical email review on patches may be a thing of
the past, and finding structure in its evolution is key to success in
adopting genai for a codebase.

That's generally a community preference - some communities I'm
involved with prefer that the context be preserved. That certainly
does become cumbersome with large patches.
I will trim more aggressively on kdevops@.

I haven't tried to feed an email thread back into an LLM, so I
might miss the mark. But, this makes sense.

docs/kdevops-terraform.md has similar information, and includes the
other providers. Section 2 could cite that file, or this patch could
modify/update that instead.

That is my take as well: Chandan, you, and I are the only cloud-based
kdevops users atm.
