I’m having a situation that after restart my AWS instance, DNS name has changed. So I want to change DISCOURSE_HOSTNAME configuration under my host’s /var/discourse/containers/standalone.yml.
I didn’t dig deep enough how unicorn manages env vars in this case. But reload the docker instance doesn’t seem to work. Because we may need to change yml config file in the future from time to time, I’m wondering how to update the variable without destroy the current docker instance.
