The Wolfi runner has no wget, but health checks outside this repository
call it: compose files copied from here up to v1.46.6 run
'wget --no-verbose --tries=1 --spider .../api/health', and the TrueNAS
catalog app renders 'wget --quiet --spider <url>'. Either replaces the
image's HEALTHCHECK, so such a container never turned healthy and a proxy
that routes on health dropped its traffic.
/usr/local/bin/wget now runs scripts/wget-shim.mjs: the URL, --spider,
-q, -nv, --tries, --timeout/-T, -O - and -O /dev/null, -S; other flags are
ignored. Exit 0 on 2xx/3xx, 1 on any other status, a refused connection
or the timeout. It follows no redirect and refuses any other output file
before sending a request, so it is no download tool. The image's own
HEALTHCHECK and the bundled compose file keep the Node probe.
