Claude Code Container – Zero-Config Docker Isolation for Claude Code

Claude Code's `--dangerouslySkipPermissions` flag is incredibly productive, but it's called "dangerous" for good reason. In practice it has deleted home directories, wiped database files, and read sensitive files completely unrelated to the project. But the default permission prompts interrupt flow constantly -- you end up spending more time approving edits than actually working.

The obvious fix is containers. But every existing approach has painful tradeoffs: - Dockerfile per project: you're now maintaining infrastructure just to use your AI assistant - devcontainer: complex config, slow to set up, breaks differently per IDE - Manual docker run: env vars don't forward, SSH keys aren't available, clipboard copy/paste stops working inside Claude sessions, and localhost:8080 from your host is unreachable from inside the container

I wanted full isolation with zero configuration. ccc (claude-code-container) handles all of this automatically, without any configuration: npm install -g claude-code-container ccc # that's it

What it does: - Creates a per-project container (named by path hash, so --continue/--resume work correctly) - Forwards host env vars, locale, timezone automatically - Mounts SSH keys and SSH agent (git push just works) - Transparent localhost proxy so Claude can reach your host's dev servers at localhost:3000, :8080, etc. even from inside the container - Clipboard works normally in Claude sessions - mise integration for per-project Node/Python/Java/Go versions - Container auto-stops when the last session exits - Chromium + chrome-devtools MCP pre-configured: Claude can open a browser, navigate pages, take screenshots, run JavaScript, and interact with your web app autonomously -- no extra setup

The transparent localhost proxy was the hardest part -- it uses iptables on Linux and a userspace proxy on macOS/Windows (Docker Desktop doesn't support --network host), with automatic fallback to host.docker.internal.

Would love feedback, especially from people who've tried other approaches to this problem.
