claudetainer

Claudetainer automates Claude Code setup within isolated devcontainers, eliminating manual environment configuration for Python, Node.js, Go, Rust, and Shell projects. It provides persistent SSH sessions with built-in terminal multiplexing (Zellij/tmux) optimized for mobile coding, allowing developers to work from anywhere without a keyboard. The tool includes specialized sub-agents, automated quality control, slash commands, and team-ready configuration sharing via GitHub. Developers and operations teams benefit from instant project initialization, secure devcontainer isolation, and push notifications for workflow awareness.

1. **Initialize Claudetainer**: Run `claudetainer init --language [PROGRAMMING_LANGUAGE] --project [PROJECT_NAME]` in your project root to generate a devcontainer configuration. 2. **Customize Dependencies**: Edit the generated `.devcontainer/devcontainer.json` to add required dependencies (e.g., `"features": {"postgresql": "15"}`). 3. **Build the Container**: Execute `claudetainer build` to create the devcontainer. Use `--cache-from` to speed up rebuilds. 4. **Verify the Environment**: Run `claudetainer exec [TEST_COMMAND]` to validate the setup. Check logs in `.claudetainer/logs/` for errors. 5. **Iterate**: Update the devcontainer config as your project evolves. Use `claudetainer update` to pull the latest changes from the template. **Tips:** - Use `claudetainer status` to check container health before debugging. - For complex setups, break dependencies into reusable modules (e.g., `"features": {"node": "18", "postgres": "15"}`). - Store sensitive environment variables in `.env` files and reference them in `devcontainer.json` using `"remoteEnv": {"DATABASE_URL": "${localEnv:DATABASE_URL}"}`.
