I'm runnign NGINX in a Docker container, and I'm trying to find a way to start it up using docker run in a way that would order my NGINX to reload its configuration every 6h. I need this to be done, because I also use Certbot in another container, and I'd like the SSL certificate renewal process to be automated and applied, and for that I neen NGINX to reload its configuration on schedule.
At this point I use the folowing docker run sequence (more or less):
docker run --restart=always -d -p 80:80 -p 443:443
--name=nginx_RevPr nginx:latest
/bin/bash -c 'while :; do sleep 6h & wait $!; nginx -s reload; done & nginx -g "daemon off;"'
The container created this way is running and working fine. The only problem I have is that I actually don't know if NGINX is really realoading its configuration. docker logs doesn't show anything.
I'd like to approach this problem in a twofold way:
- How can I output to terminal / docker logs (
echo?) the succcessfulnginx -s reloadmodifying my/bin/bash -c 'while :; do sleep 6h & wait $!; nginx -s reload; done & nginx -g "daemon off;"'? - In case I miss something (I'm a beginner for both Docker and NGINX): do you see a way to achieve the results I'd like to get in a more reasonable way?
Please don't suggest Docker Compose.
Thank you for your attention.

Sorry, but why you want to do this with bash? I think the best solution is to use a time-based job scheduler software likecronorat.

There are some problems with cron jobs in a dockerized environment. If the cron job runs on the host OS, the system isn't platform agnostic. If the cron runs within the container, it's considered an anti-pattern (containers will be harder to update). But it definitely can be done. I know that some folks run their dockerized NGINX and they pass args for a scheduled reload either in Docker Compose ordocker run. I'd like to know how (and a lot of resources over the Internet is misguiding).

OK, I got it working.
I changed the CMD args line to:
/bin/sh -c 'while :; do sleep 6h & wait $!; nginx -s reload && echo NGINX config reload for Certbot - OK; done & nginx -g "daemon off;"'
My main mistake was to enter the CMD using /bin/bash, where I should do /bin/sh. And the following nginx -s reload && echo NGINX config reload for Certbot - OK solved the problem with notyfying docker logs about config reload.
