modelrelay-worker@.service

# ModelRelay — modelrelay-worker systemd template unit
#
# This is an instantiated (template) unit. The instance name (%i) is used as
# the worker name, so you can run multiple workers on the same host:
#
#   sudo systemctl enable --now modelrelay-worker@gpu0
#   sudo systemctl enable --now modelrelay-worker@gpu1
#
# Each instance loads its own env file at /etc/modelrelay/worker-%i.env
# (e.g. worker-gpu0.env, worker-gpu1.env), falling back to the shared
# worker.env if the per-instance file doesn't exist.
#
# Install:
#   sudo cp modelrelay-worker@.service /etc/systemd/system/
#   sudo cp worker.env.example /etc/modelrelay/worker-gpu0.env  # edit values
#   sudo systemctl daemon-reload
#   sudo systemctl enable --now modelrelay-worker@gpu0
