When using with containers that have nvm pre-installed, you can use the Claude Code feature directly, and it will use the existing Node.js installation.

## Persistent configuration

This feature automatically mounts a named volume at `/claude-config` and sets `CLAUDE_CONFIG_DIR=/claude-config` in the container user's shell profiles. This consolidates all Claude data — including `~/.claude.json` — into a single persisted location, so credentials, settings, and login state survive container rebuilds with no manual configuration required.

The `postCreateCommand` provided by this feature fixes ownership of the volume directory after mounting.
