Reloading configuration
Reloading the configuration
======
It is possible to reload the configuration file without restarting the whole process by sending a SIGHUP signal to the node process.
When running the tileserver-gl docker container, the signal must be sent from within the container:
::
docker exec tileserver-gl bash -c 'kill -HUP $(ls -l /proc/*/exe | sed -n "/\/node$/s/.*proc\/\([0-9]\+\)\/exe .*/\1/p")'
- The `docker kill -s HUP tileserver-gl` command can be used when running the tileserver-gl docker container.
- The `docker-compose -s HUP tileserver-gl-service-name` can be used when tileserver-gl is run as a docker-compose service.
