My team builds a couple of Alpine images based on the N and N-1 releases based on a command like the following:

curl -L -s 'https://registry.hub.docker.com/v2/repositories/library/alpine/tags?page_size=1024' | jq '."results"[]["name"]' | tr -d \" | sort -V | grep -E "^[0-9]+[.][0-9]+$"

So right now, the latest release is 3.17 and the previous release is 3.16.  However the alpine:latest tag is 3.16:

$ docker run -it --rm alpine:latest grep PRETTY_NAME /etc/os-release
Unable to find image 'alpine:latest' locally

Status: Downloaded newer image for alpine:latest

$

Why isn't alpine:latest 3.17?
