Code Review

This pull request from Snyk upgrades the alpine base image to 3.22.2 to address security vulnerabilities. This is a welcome and necessary update. My review includes one suggestion on the Dockerfile to further enhance security and ensure build reproducibility by pinning the base image version to its content digest (SHA hash) instead of the mutable tag. This is a common best practice that prevents potential issues if the tag is ever updated to point to a different image.

[gemini-code-assist]

While upgrading to 3.22.2 is a great step for security, we can further improve the determinism and security of this build by pinning the base image to its digest. Tags are mutable and can be updated, which could lead to pulling an unexpected or compromised image. Using the digest ensures you always build from the exact same base image.

I recommend finding the SHA256 digest for alpine:3.22.2 and updating this line to use it, for example:

FROM alpine@sha256:<digest-for-alpine-3.22.2>
