+# Traefik access/error log rotation
+#
+# CONTEXT: traefik_reverse-proxy runs in Swarm `mode: global` (traefik.yaml),
+# meaning one instance runs on EACH of docker-1/docker-2/docker-3. All three
+# write to the SAME physical file via the shared CephFS bind mount
+# /volume1/docker/traefik/logs -> /traefik (identical path from any node --
+# see infra context: /volume1/docker is a shared CephFS mount).
+#
+# `copytruncate` is REQUIRED here (not the default create+signal approach):
+# Traefik has no SIGUSR1/SIGHUP "reopen log file" handling, and even if it
+# did, coordinating a reopen signal across 3 independent per-node containers
+# writing to one shared inode is unnecessary complexity. copytruncate keeps
+# every writer's existing file descriptor valid (truncates in place) so all
+# three Traefik processes keep appending to the same inode with zero
+# signaling. Tradeoff: a handful of log lines written in the exact
+# copy/truncate instant can be lost -- acceptable for diagnostic access/error
+# logs, not used for anything transactional.
+#
+# Size-triggered (not calendar-triggered) on purpose: this file can grow fast
+# under bursts (see incident that prompted this -- 15.5GB accumulated with
+# --log.level=DEBUG set). `size` is checked every time the wrapper script runs
+# (cron, every 15 minutes -- see install.sh), so it cannot balloon unbounded
+# between checks the way a plain `daily` interval would.
+#
+# Installed via install.sh on ALL THREE docker LXCs (docker-1, docker-2,
+# docker-3) -- see README.md. This is a HOST-level cron/logrotate config,
+# outside the Woodpecker/stack-deploy.sh pipeline (docker stack deploy has no
+# mechanism to touch host cron), so it must be applied manually once per node,
+# not via a stack redeploy.
