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.

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.

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? > + > +### Generated files have wrong references > + > +Run `make cloud-update` to fix references from `.generated` to `.static`. 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. > + > +### 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 > + > +## See Also > + > +- [AWS Instance Types](https://aws.amazon.com/ec2/instance-types/) > +- [Azure VM Sizes](https://docs.microsoft.com/en-us/azure/virtual-machines/sizes) > +- [GCE Machine Types](https://cloud.google.com/compute/docs/machine-types) > +- [kdevops Terraform Documentation](terraform.md) > diff --git a/scripts/aws-cli b/scripts/aws-cli > new file mode 100755 > index 00000000..6cacce8b > --- /dev/null > +++ b/scripts/aws-cli > @@ -0,0 +1,436 @@ > +#!/usr/bin/env python3 > +# SPDX-License-Identifier: MIT > +""" > +AWS CLI tool for kdevops > + > +A structured CLI tool that wraps AWS CLI commands and provides access to > +AWS cloud provider functionality for dynamic configuration generation > +and resource management. > +""" > + > +import argparse > +import json > +import sys > +import os > +from typing import Dict, List, Any, Optional, Tuple > +from pathlib import Path > + > +# Import the AWS API functions > +try: > + from aws_api import ( > + check_aws_cli, > + get_instance_types, > + get_regions, > + get_availability_zones, > + get_pricing_info, > + generate_instance_types_kconfig, > + generate_regions_kconfig, > + generate_instance_families_kconfig, > + generate_gpu_amis_kconfig, > + ) > +except ImportError: > + # Try to import from scripts directory if not in path > + sys.path.insert(0, os.path.dirname(os.path.abspath(__file__))) > + from aws_api import ( > + check_aws_cli, > + get_instance_types, > + get_regions, > + get_availability_zones, > + get_pricing_info, > + generate_instance_types_kconfig, > + generate_regions_kconfig, > + generate_instance_families_kconfig, > + generate_gpu_amis_kconfig, > + ) > + > + > +class AWSCLI: > + """AWS CLI interface for kdevops""" > + > + def __init__(self, output_format: str = "json"): > + """ > + Initialize the CLI with specified output format > + > + Args: > + output_format: 'json' or 'text' for output formatting > + """ > + self.output_format = output_format > + self.aws_available = check_aws_cli() > + > + def output(self, data: Any, headers: Optional[List[str]] = None): > + """ > + Output data in the specified format > + > + Args: > + data: Data to output (dict, list, or primitive) > + headers: Column headers for text format (optional) > + """ > + if self.output_format == "json": > + print(json.dumps(data, indent=2)) > + else: > + # Human-readable text format > + if isinstance(data, list): > + if data and isinstance(data[0], dict): > + # Table format for list of dicts > + if not headers: > + headers = list(data[0].keys()) if data else [] > + > + if headers: > + # Calculate column widths > + widths = {h: len(h) for h in headers} > + for item in data: > + for h in headers: > + val = str(item.get(h, "")) > + widths[h] = max(widths[h], len(val)) > + > + # Print header > + header_line = " | ".join(h.ljust(widths[h]) for h in headers) > + print(header_line) > + print("-" * len(header_line)) > + > + # Print rows > + for item in data: > + row = " | ".join( > + str(item.get(h, "")).ljust(widths[h]) for h in headers > + ) > + print(row) > + else: > + # Simple list > + for item in data: > + print(item) > + elif isinstance(data, dict): > + # Key-value format > + max_key_len = max(len(k) for k in data.keys()) if data else 0 > + for key, value in data.items(): > + print(f"{key.ljust(max_key_len)} : {value}") > + else: > + # Simple value > + print(data) > + > + def list_instance_types( > + self, > + family: Optional[str] = None, > + region: Optional[str] = None, > + max_results: int = 100, > + ) -> List[Dict[str, Any]]: > + """ > + List instance types > + > + Args: > + family: Filter by instance family (e.g., 'm5', 't3') > + region: AWS region to query > + max_results: Maximum number of results to return > + > + Returns: > + List of instance type information > + """ > + if not self.aws_available: > + return [ > + { > + "error": "AWS CLI not found.

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.

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

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. > > +### Generated files have wrong references > > + > > +Run `make cloud-update` to fix references from `.generated` to `.static`. > > Again, I'm missing the difference between .generated and .static.

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. > > +def get_pricing_info(region: str = "us-east-1") -> Dict[str, Dict[str, float]]: > > + """ > > + Get pricing information for instance types. > > + > > + Note: AWS Pricing API requires us-east-1 region. > > + Returns a simplified pricing structure. > > + > > + Args: > > + region: AWS region for pricing > > + > > + Returns: > > + Dictionary mapping instance types to pricing info > > + """ > > + # For simplicity, we'll use hardcoded common instance prices > > + # In production, you'd query the AWS Pricing API > > 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). 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. > Also, see below: I'm not sure why we need to keep a lot of default > information around in this script.

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. > We always have the safety net of git to quickly get back to a working > configuration: something like "git reset --hard". 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. > > +def get_aws_summary() -> tuple[bool, str]: > > + """ > > + Get a summary of AWS configurations using aws-cli. > > + Returns (success, summary_string) > > + """ > > + script_dir = os.path.dirname(os.path.abspath(__file__)) > > + cli_path = os.path.join(script_dir, "aws-cli") > > + > > + try: > > + # Check if AWS CLI is available > > + result = subprocess.run( > > + ["aws", "--version"], > > + capture_output=True, > > + text=True, > > + check=False, > > + ) > > + > > + if result.returncode != 0: > > + return False, "AWS: AWS CLI not installed - using defaults" > > + > > + # Check if credentials are configured > > + result = subprocess.run( > > + ["aws", "sts", "get-caller-identity"], > > + capture_output=True, > > + text=True, > > + check=False, > > + ) > > + > > + if result.returncode != 0: > > + return False, "AWS: Credentials not configured - using defaults" > > + > > + # Get instance types count > > + result = subprocess.run( > > + [ > > + cli_path, > > + "--output", > > + "json", > > + "instance-types", > > + "list", > > + "--max-results", > > + "100", > > + ], > > + capture_output=True, > > + text=True, > > + check=False, > > + ) > > + > > + if result.returncode != 0: > > + return False, "AWS: Error querying API - using defaults" > > Seems like the process should just fail here.

Sure. > Again, it's always quite possible that I've misread something. 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.
