TLDR;

Build your Claude Code image with Docker:

FROM node:20-slim

# Create a non-root user for safer execution
RUN useradd -m -u 1001 claude

# Install Claude Code CLI globally
RUN npm install -g @anthropic-ai/claude-code

# Set the working directory
WORKDIR /workspace

# Switch to non-root user
USER claude

ENTRYPOINT ["claude"]

Then run it, binding local credentials to it (optional)

docker run -it --rm \
  -v ~/.claude:/home/claude/.claude \
  -v ~/.claude.json:/home/claude/.claude.json \
  -v $(pwd):/workspace \
  claude-code:latest --dangerously-skip-permissions

Thats it! I recommend setting up some kind of alias for this, eg xclaude - that is more convenient.
