Piping curl output directly to bash is a security anti-pattern. Consider downloading the script first, verifying it, then executing it:

RUN curl -fsSL https://deb.nodesource.com/setup_20.x -o setup_node.sh && \
    bash setup_node.sh && \
    rm setup_node.sh && \
    apt-get install -y nodejs && \

Alternatively, if the @anthropic-ai/claude-code CLI doesn't have a hard runtime dependency on Node.js, consider whether you can use bun alone without installing Node.js, which would simplify the image.

Suggested change

	curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && \
	curl -fsSL https://deb.nodesource.com/setup_20.x -o setup_node.sh && \
	bash setup_node.sh && \
	rm setup_node.sh && \

[nitpick] Using the latest tag for the base image can lead to non-reproducible builds. Consider pinning to a specific version:

COPY --from=oven/bun:1.1.38 /usr/local/bin/bun /usr/local/bin/bun

Check the official bun releases for the most recent stable version.

Suggested change

	COPY --from=oven/bun:latest /usr/local/bin/bun /usr/local/bin/bun
	COPY --from=oven/bun:1.1.38 /usr/local/bin/bun /usr/local/bin/bun

[nitpick] Consider pinning the @anthropic-ai/claude-code package to a specific version for reproducible builds:

RUN bun install -g @anthropic-ai/claude-code@2.0.43

This ensures consistent behavior across deployments and makes it easier to track which version is being used.

Suggested change

	RUN bun install -g @anthropic-ai/claude-code
	RUN bun install -g @anthropic-ai/claude-code@2.0.43
