- gunicorn: 3 workers -> 2 (this workload isn't CPU-bound per DEPLOYMENT.md's own sizing), add --preload so workers share immutable memory via copy-on-write instead of each independently importing Django, add --max-requests so a worker that renders a WeasyPrint invoice doesn't carry that memory forever. - Postgres: trim shared_buffers/max_connections from the image defaults (128MB/100), sized for a ~0.2GB dataset instead. - Redis: cap with --maxmemory as a ceiling, not a saving.

# A dev/test deployment on a server that ALREADY runs Caddy on :80/:443.

#
|
|
# docker compose -f compose.behind-proxy.yaml up -d
|
|
#
|
|
# The difference from compose.yaml is only what listens on the network: no caddy service, and
|
|
# web publishes on the loopback instead of the public interface. The host's Caddy reverse
|
|
# proxies to it (see DEPLOYMENT.md, "Behind an existing Caddy").
|
|
#
|
|
# Publishing on 127.0.0.1 and not 0.0.0.0 is the point: bound to all interfaces, a test
|
|
# instance is reachable on http://<server-ip>:8001 with no TLS, bypassing the proxy and every
|
|
# security header with it.
