Codex CLI (codexcli)

Installs OpenAI Codex CLI using the official standalone installer. The installer downloads a pre-built statically-linked (musl) binary, so it works on all Linux distributions without requiring Node.js or any other runtime.

Usage

"features": {
    "ghcr.io/cjcrobin/devcontainer-features/codexcli:1": {}
}

How It Works

1. Detects the available package manager (apt-get, apk, dnf, yum, zypper, pacman).
2. Ensures curl and ca-certificates are installed (installs them if missing).
3. Runs the official installer: curl -fsSL https://chatgpt.com/codex/install.sh | sh
4. Verifies the codex binary is available and symlinks it to /usr/local/bin for system-wide access.

No Presets

This feature does not configure any API keys, models, or preferences. Run codex after container creation to sign in or set up your environment.
