# --- img.dieschoenewolke.de: public read-only OCI mirror ---------------------
# Merge this block into /root/Compose/Webserver/NginxEdge/nginx/default.conf
# (write in place: `cat new > default.conf`) and force-recreate edge-nginx.
#
# docker/containerd/skopeo/crane all speak plain GET+HEAD with a Go or Docker
# user agent. CRS treats those as scanners, so AppSec is off for this host - the
# CrowdSec IP bouncer still applies and the registry itself is read-only.
# `limit_except GET` is the second lock: even if zot were reconfigured, the edge
# refuses every write verb.
#
# A path-based /v2/ on git.dieschoenewolke.de is NOT an option: OCI clients
# build the repository name from <host>/<path>, so a shared host would force
# names like git.dieschoenewolke.de/distroless/static and the /v2/ base path
# would have to be stripped by the edge. docker's ping is
# GET /v2/ (not /git/v2/), so the mirror gets its own name. The wildcard
# *.dieschoenewolke.de certificate already covers it - no cert change.
