aicage 0.0.9

Runs agentic coding assistants in docker containers

aicage

Run your favorite AI coding agents comfortably in Docker.

Why use aicage?

Agents need deep access (read code, run shells, install deps). Their built-in safety checks are naturally limited.

Running agents in containers gives a hard boundary - while the experience stays the same. See Why cage agents? for the full rationale.

Quickstart

• Prerequisites:

  • Docker
  • Python 3.10+ and pipx

• Install:

  pipx install aicage
  

• Navigate to your project directory.

• Use one of these commands:

  aicage claude
  aicage cline
  aicage codex
  aicage droid
  

Base images

The first run asks which base image to use; pick Ubuntu or whatever matches your Linux distro.

Base	Distro	Notes
ubuntu	Ubuntu	Good default for most users
debian	Debian	For Debian users
fedora	Fedora	For RedHat/Fedora users
alpine	Alpine	Minimal footprint; experimental
node	Ubuntu	Official Node image (all base images have Node)
act	Ubuntu	Default runner image from act (act runs GitHub Actions locally)

All base images have the same stack of tools installed.

Agents

CLI	Agent	Homepage
claude	Claude Code	https://claude.com/product/claude-code
cline	Cline CLI	https://docs.cline.bot/cline-cli
codex	Codex CLI	https://developers.openai.com/codex/cli
droid	Factory CLI	https://factory.ai/product/cli

Your existing CLI config for each tool is mounted inside the container so you can keep using your preferences and credentials.

aicage options

• --dry-run prints the composed docker run command without executing it.

Why cage agents?

AI coding agents read your code, run shells, install packages, and edit files. That power is useful, but granting it directly on the host expands your risk surface.

Where built-in safety is limited:

• Allow/deny lists only cover known patterns; unexpected commands or attack paths can slip through.
• Some tools work fully only after relaxing their own safety modes, broadening what they can touch.
• “Read-only project” features are software rules. Other projects and files still sit alongside them on the same host.

How aicage mitigates this:

• Containers create a hard boundary: the agent can access only what you explicitly mount. Day-to-day use stays familiar—just with the host kept out of reach.
