# Nginx Proxy Manager upstream config for the pawfeed-1/2/3 replicas.
# See docker/SCALING-ROADMAP.md (Schritt 3).
#
# Paste into either:
#   - the pawfeed.org Proxy Host's "Advanced" tab (custom Nginx config,
#     applies only to that host), or
#   - a global snippet under /data/nginx/custom/*.conf on the NPM
#     container (applies to all proxy hosts — use only if the upstream
#     block needs to be shared).
#
# If using the Advanced tab, the upstream block itself typically needs to
# go in a global snippet (http-context), while the proxy_pass line below
# goes in that Proxy Host's Advanced tab. Verify against the NPM version in
# use — the split differs slightly between NPM releases.
