# terriajs-server registers no SIGTERM/SIGINT handlers, and node:24-slim has no init
# system, so without tini as PID 1, `docker stop` (and Kubernetes' pod termination,
# which works the same way) has nothing to catch the signal - the container just sits
# until the grace period expires and it gets SIGKILLed. tini forwards the signal to
# node and reaps zombies, so shutdown is immediate. Installed as root, before USER
# node, since apt-get needs root.
RUN apt-get update && apt-get install -y --no-install-recommends tini \
