nwaf_update service and nginx

Hi all,
Recent user of Nemesida, I integrated the free WAF into our existing reverse proxy, which is executed in a Docker container (nginx + jwilder/docker-gen + letsencrypt companion), by modifying the proxy docker image to add Nemesida WAF module.
I encounter a problem when executing the "nwaf_update" service: after downloading the rules, it stops the nginx service and restarts it to make it take the downloaded rules into account. But this behavior stops the container.
Is there a way to change the "nwaf_update" service to send a SIGHUP signal to nginx, rather than restarting the nginx service?
Thank you,
Pascal

Hello, we don't have such problem at our docker images. You can look for an example. Your main process or last command in main process of docker image shouldn't be nginx.
 
Hi,
Sorry for the late reply. I finally succeeded in getting the expected behaviour by changing the Dockerfile entrypoint with a custom script that calls /docker-entrypoint.sh with nginx -g 'daemon off;' in parameter, and then enter an infinite loop.
Regards
Pascal
