This COPY . . will send the entire build context into the image. Since the repo has no .dockerignore, it will also include directories like .git/ (and potentially target/ after local builds), which slows builds and can invalidate cache unexpectedly. Consider adding a .dockerignore (or narrowing what gets copied) to keep the build context small and caching effective.

RUN touch src/main.rs updates the file timestamp on every build, which makes this layer (and everything after it) effectively uncacheable and reduces build reproducibility. Removing this line (or replacing it with a deterministic cache-busting strategy only when needed) will preserve Docker layer caching and speed up builds.

Suggested change
RUN touch src/main.rs

The runtime stage uses FROM alpine:latest, which pins your base image to a mutable latest tag on Docker Hub; if that tag is ever compromised or updated with a malicious or vulnerable image, every build using this Dockerfile can silently inherit the compromise. To make builds deterministic and reduce supply-chain risk, pin the base image to an immutable reference such as a specific version tag or image digest under your control.
