Also, when you start hosting more than 2-3 services, keeping them up-to-date might become a hassle which you can forget. For docker-based hosting I’d recommend you setup watchtower, which can keep your servives up-to-date for you.
I would caution against automatic updates! Notifications, yes absolutely. But automatically updating things is a great way to have things break suddenly when you’re not in a good place to troubleshoot.
