Greptile Overview

Greptile Summary

This PR fixes the nightly container testing suite by addressing command execution issues when running containers as root. The changes modify the Docker test script (ci/docker/test_image.sh) to handle the environment properly after switching container users. Specifically, it adds gcc to apt dependencies for package compilation requirements, switches from direct pip command to python -m pip to ensure pip is accessible through Python's module system, and changes pytest invocations from pytest to python -m pytest for consistent module access. These changes resolve PATH and Python module installation context issues that occur when containers run as root and then switch to different users, ensuring the testing commands are properly available regardless of the user context.
