Anything terribly wrong with it?
Or something to change or add because of better practice?
Zammads docker compose is actually amazingly well done.
Literally just git clone, up -d, and go to correct port.
But restoring backups was bit unexpected hurdle, though relatively easy to google up and piece together process from few answers.
Then there was just few env variables when it comes to reverse proxy
We are still not running it in production, still testing features and whats what, but deploy, backups and restore are the first steps to get some confidence.
So far I absolutely love how it looks and how it feels and what it offers.
