Code Review

This pull request, automatically generated by Snyk, upgrades the nginx base image from 1.29.3-alpine to 1.29.5-alpine to resolve several security vulnerabilities. The change is correct and addresses the security issues. I've added one suggestion to further improve security and build reproducibility by pinning the Docker image to its content digest.

For enhanced security and to ensure reproducible builds, it's recommended to pin the base image version using its content digest (SHA256 hash). This practice mitigates risks from tag mutability, where the 1.29.5-alpine tag could be updated to point to a different, potentially malicious, image. Pinning ensures you are always pulling the exact same image bits.

You can find the digest for the image on Docker Hub or by pulling the image and inspecting it (docker inspect nginx:1.29.5-alpine).

Example format:

FROM nginx:1.29.5-alpine@sha256:<image_digest>
