# WARNING: This script should be kept in sync with the file used by Chef:
# vespa-cookbooks/hosted/files/default/prepost-instance.sh
# TODO: Remove the above cookbook file (with the down-side that a new script
# requires a new vespa release, instead of just a hosted release).
#
# Usage: nodectl-instance.sh [resume|start|stop|suspend]
#
# resume: Set the node "in service" by e.g. undraining container traffic
#
# start: Start services on the node. Can be seen as a boot of a non-Docker node.
# start can be assumed to have completed successfully.
#
# stop: Stop services on the node. Can be seen as a shutdown of a non-Docker node.
#
# suspend: Prepare for a short suspension, e.g. there's a pending upgrade. Set the
# node "out of service" by draining container traffic, and flush index for a
# quick start after the suspension. There's no need to stop.
