Greptile Summary

This PR updates dependencies for the jailbreak detection Docker containers to address known vulnerabilities. The changes include upgrading the Python base image from 3.10 to 3.11, updating the GPU image from a CUDA-only base to a PyTorch 2.9.1 image, and updating dependency versions (starlette, transformers, torch, nemoguardrails).

Key Changes:

• CPU container: Upgraded from python:3.10-slim to python:3.11-slim
• GPU container: Replaced nvidia/cuda:12.3.1 with pytorch/pytorch:2.9.1-cuda12.6-cudnn9-runtime, removing explicit Python installation
• Dependencies: Updated starlette (0.27.0→0.50.0), transformers (4.56.0→4.57.6), torch (2.8.0→2.9.1), nemoguardrails (0.7.0→0.14.0)
• Removed --no-cache-dir flag from pip install commands
• Changed from python to python3 for GPT2 predownload in CPU image, but inconsistently used in GPU image

Issues Found:

• CPU Dockerfile ENTRYPOINT uses /usr/local/bin/python which may not exist in Python 3.11-slim; should use python3
• GPU Dockerfile-GPU has inconsistent Python command usage (line 27 uses python but ENTRYPOINT uses python3)
• These runtime failures would occur when containers start

Confidence Score: 2/5

• This PR has critical runtime errors that will cause container startup failures - Python binary path mismatches in ENTRYPOINT commands must be fixed before merging.
• The PR introduces two critical logic errors in Docker ENTRYPOINT configurations that will cause runtime failures. The CPU Dockerfile uses /usr/local/bin/python which doesn't exist in Python 3.11-slim, and the GPU Dockerfile has inconsistent Python binary references between build steps and ENTRYPOINT. While the dependency updates themselves are reasonable and the base image upgrades are beneficial, these entrypoint bugs are blocking issues that would prevent the containers from running at all. The author's claim that containers build and run locally suggests these issues may have been overlooked during testing.
• Both nemoguardrails/library/jailbreak_detection/Dockerfile and nemoguardrails/library/jailbreak_detection/Dockerfile-GPU require fixes to the Python binary paths in ENTRYPOINT commands before this PR can be safely merged.

Important Files Changed

Filename	Overview
nemoguardrails/library/jailbreak_detection/Dockerfile	Upgraded base image from Python 3.10 to 3.11. Changed Python invocation from python to python3 on line 27. ENTRYPOINT still uses /usr/local/bin/python which may not exist - should be python3.
nemoguardrails/library/jailbreak_detection/Dockerfile-GPU	Replaced CUDA base image with PyTorch image, improving dependency management. However, Python command changed from python3 to python on line 27, inconsistent with explicit python3 in ENTRYPOINT. Changed pip to --no-cache-dir flag removal. Removed explicit Python installation (now in base image).
nemoguardrails/library/jailbreak_detection/requirements.txt	Updated dependency versions: starlette (0.27.0→0.50.0), transformers (4.56.0→4.57.6), torch (2.8.0→2.9.1), and nemoguardrails (0.7.0→0.14.0). Versions align with main project dependencies. Minor version bumps with backward compatibility maintained.

   logic: Python 3.11-slim base image may not have /usr/local/bin/python. The command on line 27 uses python3, but ENTRYPOINT uses /usr/local/bin/python. This will fail at runtime.\n\n

**logic:** Inconsistent Python command - changed from `python3` to `python`, but ENTRYPOINT on line 33 explicitly uses `python3`. PyTorch base images typically have `python3` but not necessarily a `python` symlink. For consistency and reliability, use `python3`.\n\n```suggestion\nRUN python3 -c \"from transformers import GPT2LMHeadModel, GPT2TokenizerFast; GPT2LMHeadModel.from_pretrained('gpt2-large'); GPT2TokenizerFast.from_pretrained('gpt2-large');\"\n```
