claude-container

Run Claude Code inside an Arch Linux Docker container that closely mirrors a local development environment, while limiting access to sensitive files on the host.

Features

  • Arch Linux–based image
  • Runs as the host user (same username, UID, GID)
  • Per-project isolation: Each project gets its own container (identified by project path hash)
  • Shared persistent home: All containers mount the same home directory from XDG_DATA_HOME, allowing tools to persist across projects
  • Sudo access: Claude agent can install project-specific dependencies that persist in the stopped container
  • Hard linking support: Can hard link files like ~/.gitconfig to share configurations with containers
  • Mounts only the current project directory (same absolute path inside container)
  • Security boundary: No access to SSH keys, passwords, or full $HOME (intentionally prevents remote code pushes)
  • Simple shell function (claude) to launch interactively

Install

Change to your projects directory and clone the repository:

cd ~/Projects/
git clone https://git.jeena.net/jeena/claude-container.git

Source the helper file claude.aliases in your shell configuration (.bashrc or .zshrc) so the claude function is available in new sessions.

source ~/Projects/claude-container/claude.aliases

We set up the XDG_DATA_HOME/claude-container/container-home directory as a central $HOME inside the container, independent of the session or project directory we start in. This persists the whole $HOME from inside the container so everything Claude Code writes into config files etc. persists there.

Environment Variables

  • XDG_DATA_HOME: Override default data directory (default: ~/.local/share)
  • ANTHROPIC_API_KEY: Your Anthropic API key (required, read from host environment)
  • ANTHROPIC_BASE_URL: Override the API base URL (optional)

Usage

From any project directory:

claude

The image is built automatically on first use if it does not already exist. Claude Code starts inside the container with the current directory mounted and set as the working directory.

Cleanup

To remove all containers, the image, and the persistent home directory:

~/Projects/claude-container/force-cleanup.sh
