- deploy/docker-compose.yml: pinned-tag ghcr image, hardened (cap_drop ALL + minimal cap_add, no-new-privileges, panel bound to 127.0.0.1 only). Apache itself runs on the host (spec 10.5), fragment at deploy/apache/. - Alternative reverse-proxy fragments: nginx (+certbot sidecar), Caddy (automatic ACME), Traefik (+acme.json PEM extraction script). - .github/workflows/release.yml: tag-triggered ghcr.io publish, version piped from the git tag into both the binary ldflags and the image tag (spec 10.1). - Closed a gap from Phase 1: logrotate was installed but never invoked; wired up build/logrotate-mail.conf + logrotate-loop.sh + a supervisor program (copytruncate, since postlogd holds mail.log open with nothing to signal on rotation). - README rewritten: site requirements checklist, reverse-proxy comparison, DNS setup (server- vs domain-level), IP warmup, backup/restore vs domain export/import, fixed-tag rationale, machine requirements.

# Alternative reverse-proxy: nginx (spec 10.3). PEM files land on the host
|
|
# exactly like the Apache+certbot scenario — nginx and certbot are close
|
|
# cousins here, both writing/reading plain PEM under /etc/letsencrypt.
|
|
#
|
|
# This is a FRAGMENT, not a full replacement for ../docker-compose.yml: it
|
|
# adds an nginx + certbot pair and removes the panel's host port publish (nginx
|
|
# takes over 80/443 and proxies to the panel over the compose network
|
|
# instead). Merge it with the base file — run this from the deploy/ directory
|
|
# (Compose resolves every relative path in both files against the directory of
|
|
# the FIRST -f file, i.e. deploy/, which is why paths below are ./nginx/...):
|
|
#
|
|
# docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml up -d
|
|
#
|
|
# First-run certificate issuance (webroot method, before nginx has a cert to
|
|
# serve — run once):
|
|
# docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml \
|
|
# run --rm certbot certonly --webroot -w /var/www/certbot \
|
|
# -d mail.example.com --email you@example.com --agree-tos --no-eff-email
