GPU Access Challenges with Codex CLI in Linux Containers

Users discovered that GPU resources aren’t detected in Linux container environments when running AI model training scripts with codex cli, while claude code functions normally. AI analysis reveals that codex cli operates in a sandbox, causing GPU isolation. Attempts to launch with parameters like ‘codex –sandbox danger-full-access’ only partially resolve the issue, hindering automated bug fixing workflows. Users are seeking community suggestions to explore more comprehensive solutions. This issue focuses on resource management optimization for AI tools in containerized environments, offering practical value for enhancing development efficiency and GPU access technology.
