Hi, I'm running HAproxy (1.7 or 1.8) inside Docker containers, through by SystemD unit files on the host. I would like to force HAproxy to reload certificates (bind ssl crt) with minimal downtime whenever they are renewed on disk (another process inside the container).
I tried to send HUP signals to HAproxy through Docker, but this doesn't seem to work. Of course, any other signal just kills the containers, so there is a downtime of about 30s to 1min. Any idea?
