Reload 1 container from another?

How do you restart 1 container, from another?

I've read to use watch scripts, cron jobs, etc... but isn't there a more direct way?

The problem is I'm running a container ("mailu/mailu") and it just won't read the symlinks that my certbot container makes ("linuxserver/letsencrypt"), mailu wants hard/deep copies and its own nginx has to reload upon them (I have a similar niche/edge-case problem with my "gitea/gitea" container as well).

I *thought* I could use a post-hook script with certbot, and while that will perform the deep copies, I'm puzzled on how to run the certbot hooks to trigger a restart of the mailu container. Whatever I do, I want to make sure as soon as there is new certs, mailu is immediately restarted/reloaded, but I'm curious how to do this as I'll undoubtedly run into this again.

Why don't you put your certs on a volume and expose it to the container, then just restart the container nightly?

I'm using Traefik for my certs and have a script to export them and put them in a shared location which is exposed to my containers that want copies locally (like OpenVPNAS)

I just don't want to restart. I do see a crude proc.sock method which forcefully works, but I'll just leave it with cron for now. I'm sure there has to be a way to trap a signal with the host docker, use some namespace or something right, but later to that :-).
