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>

RUN apk --no-cache --no-progress add \
bash \
ca-certificates \
