+# Minimal chrony NTP server for the lab boot LAN. Diskless workstations get this
+# host as their time source via DHCP option 42 (dnsmasq), so they never reach the
+# public NTP pool (no workstation egress). Config is bind-mounted from
+# chrony.conf in docker-compose.yml. Build our own so the version is pinned.
+FROM alpine:3.20
+RUN apk add --no-cache chrony
+# -d: run in the foreground (don't daemonise) so the container stays up and logs
+# to stdout for `docker compose logs`.
+ENTRYPOINT ["chronyd", "-d", "-f", "/etc/chrony/chrony.conf"]
